Subject: P2P/ v1.0 to P2P v1.0.x Interconnectivity over TCP/IP TCP/IP address within the same workstation, in P2P/2 v1.0.1, is 1376 and 5001 for P2P/2 v1.0. For example to convert address books from v1.0 to v1.0.1, use 'Export' from the P2P v1.0.1 Address Book utility and then edit the exported file (now in ASCII), and change 5001 to 1376. Next this should be imported.

Subject:WfWGs v3.1 and NETBIOS Netware Requestor bundled with WfWGs has not got netbios.exe and needs to be obtained and installed separately, if Novell netbios is required.

Subject:ISDN - Called Party sub-addressing If using CdPSA with IBM ISDN card, make sure it is properly configured at the called station.

Subject:ISDN - SCII Card For SCii software and Hardware installation consult SCii pubs. Also refer to P2P/Windows README file on diskette one for further practical tips.

Subject:Installation "Serious Disk Error" if Serious Disk Error msg is popped out during installation of P2P/W, then decrease the size of virtual memory(swapper file).

Subject:Async Reliability Problem If P2P/2 v1.0 over Async used for a long time it may crash the system. To get over this, specify a large swapper file (20MB). P2P v1.0.1 handles this thru better memory management.

================================================================== Subject:ActionMedia without the Capture card The effect of using AMII card without Capture card (the card that plugs on to AMII), is that the Dual View will be greyed out. In addition only local software emulation or remote software emulation/Video can be viewed at any one time.

================================================================== Subject: P2P Clip & Windows for Workgroups clip/DDE Interoperability - P2P's Clip provides for sharing of clipboard/DDE between communicating workstations; Microsoft's Windows For Workgroups offers the same via a different user model. - This note confirms that P2P's Clip will happily co-exist with W4W, and, furthermore, will interoperate as follows - - Suppose we have 3 PCs, A, B & C; A & B are running W4W and have shared a page in the Clipbook such that clipboard and DDE operations are shared between them; B nows calls C using P2P and shares Clip onto the call. If A and C each run an application such as Excel, Lotus, or whatever, then if A copies cells to the clipboard, C can Paste (clipboard) and/or Paste Link (DDE) and it will work. (The reverse direction and any other combinations of machines will     also work). - Note also that, in the scenario above, C can be running either OS/2 or Windows (the same restrictions would apply as in the general case     of two machines of differing operating systems for P2P Clip).

================================================================== Subject:P2P Clip & NEOS Peer LAN clip/DDE Interoperability - P2P's Clip provides for sharing of clipboard/DDE between communicating workstations; IBM's NEOS Peer LAN offers the same via a different user model. - This note confirms that P2P's Clip will happily co-exist with Peer LAN, and, furthermore, will interoperate as follows - - Suppose we have 3 PCs, A, B & C; A & B are running Peer LAN; B now calls C using P2P and shares Clip onto the call. If A and C     each run an application such as Excel, Lotus, or whatever, then if      A copies cells to the clipboard, B then uses Peer LAN "Network      Clip/DDE" to "Copy" the clipboard and "Get" the data from A; then C can Paste (clipboard) and/or Paste Link (DDE) and it will work. (The reverse direction and any other combinations of machines will     also work). - Note also that, in the scenario above, C can be running either OS/2 or Windows (the same restrictions would apply as in the general case     of two machines of differing operating systems for P2P Clip).

=
================================================================== Subject: P2P Clip & Windows for Workgroups clip/DDE Interoperability - A minor snag has been uncovered with the way we got Clip to happily coexist with W4W. These notes explain how W4W works, what we did to cope with it, and why there's a small snagette. In the following remember that "clipbook" is W4W's clipboard sharing utility. - Suppose machines B and C are running W4W, and C and D are running P2P with Clip. - D copies something to the clipboard; Clip sends the list of clipboard formats to C, where Clip copies them to the clipboard; W4W clipbook notices this, and copies all the formats and the data (so Clip fetches    all the data across which was delayed up to that point and renders it) onto its shared page for B; THEN (rot its socks) it ADDS a private format called "Clipbook Preview" to the clipboard on C WITHOUT emptying it    first; Clip gets a message saying the clipboard has been updated, reads the contents and sends it all back to D (whence it originally came). - That was considered undesirable, so what we did was: when the message arrives to say "clipboard updated" we check to see if the format Clipbook Preview exists on the clipboard and if it does we ignore the update (so it's not "bounced back" to D). - Then, however, suppose B updates it clipboard, W4W copies it to     C which gets its clipboard emptied and filled with new formats and data, *including* "Clipbook Preview"; now Clip gets the update message but ignores it because of the Clipbook Preview format. - To fix that, we used the fact that whenever Clip fills a clipboard it adds its own format (for Windows "P2P/W-CLIP") to the others. So, now when Clip gets a "clipboard update" message, it checks to    see if the formats include Clipbook Preview *AND* P2P/W-CLIP, in     which case the message is ignored (because W4W must have added its     format without emptying, which it only does when it is *reading*     the clipboard to copy to its shared page). When B's page gets copied to C, W4W empties the clipboard first, hence P2P/s format is    missing, so we then correctly pick up the message and send off the contents. - Snagette: Suppose we now add machine A which is connected by P2P and Clip to B. (Remember B is sharing clipbook via W4W with C, C    is connected by P2P and Clip to D). Still following? Now A copies some stuff to the clipboard; Clip sends it to B, adding its own format of P2P/W-CLIP to the others (hear it coming..?..); B copies it to C via W4W which adds its own format of Clipbook Preview; Clip on C gets the "clipboard updated" message, but IGNORES it    because both formats are present. - We have decided to live with the snagette. Why? Because - 1 it's a pretty unlikely scenario for anyone to hit. 2 since B and C are both running P2P, they could P2P call each other over the LAN (they must have a LAN because they are connected       by W4W) making a 4 way P2P & Clip call, and do their clipboard sharing that way; any shared page on the clipbook between B and C should be unshared before doing it; then everything will be       fine. i.e. there is a work-around.

================================================================== Subject: Run-time DLLs for IBMC, and CommonView Products which are sold, and include run-time DLLs from other products, may encounter problems. For example, suppose P2P includes DLLs which are part of the Glockenspiel CommonView product; those DLLs are installed on   the user's machine in his libpath and are used by P2P. Now suppose that the user buys another product which includes the same Glockenspiel DLLs, these new ones are installed on the libpath, maybe overwriting the P2P ones, or maybe being put on the libpath before P2P's. Now when P2P runs it will use the new ones. This may cause problems. Further, suppose that the P2P ones were advanced ones with new features, and the second product the user installed had older versions lacking the new features. Now P2P will not run because the features are missing; worse, the P2P ones may have been overwritten and P2P has to be re-installed; then the P2P ones may not work with the user's second product (worst case!) in which case the user cannot use both products on his machine at the same time. P2P ---    There are two potential areas where we could hit this problem - IBMC Ibm C has a runtime DLL called CRTLIB.DLL. P2P does NOT use this, instead we have a system (designed by Andy Key together with DCL) in which all the ibmc run-time routines are kept in our own-named DLPCRT.DLL which thus uniquely named will not clash with any of the user's CRTLIB.DLLs. This was done because many applications are written in C (and the   particularly name CRTLIB is common to many C compilers other than IBM's)    and a clash was considered quite likely. CommonView --    Glockenspiel's CommonView, as used by P2P, needs 4 DLLs, called - GLFS31DP.DLL GLCV31DP.DLL GLSH31DP.DLL GLTD31DP.DLL P2P DOES use these, they are installed by the Install program and exist in the C:\P2P directory along with all the other EXEs and DLLs. If the user installs another product which uses the same DLLs, the problems described above could occur. It was considered unlikely that a user would install another product written using CommonView and hit a clash problem. P2P uses CommonView 3.0 Beta 3 DLLs which are very recent.

================================================================== Subject:Address Book Format P2P Address Book format (and content) are not consistent with any other product like: Time and Place/2, Lotus Notes, (using Vendor Independent Messaging interface) WPSHARE93 style (as on OS2TOOLS), VM Names file style. Address Book Synchronization/2 Lotus cc:Mail (VIM) In P2P defence, the address book interface was coded to allow for using various formats. P2P can accept interface DLLs (called Database Support Modules) which allow it to access other address book formats. The problem is not design but the fact that no other DSMs have been written.

================================================================== Subject: Information on VideoLabs FlexCam Camera From the FlexCam box... ---  FlexCam Desktop Color Video & Sound is a high resolution, integrated color camera and microphone. FlexCam's video output is  industry standard NTSC or PAL. And Flexcam's low noise, directional microphones deliver top-quality, line-level stereo audio. FlexCam's  60 degree swivel "head" and 18" flexible gooseneck offer precise   camera positioning. And the adjustable focus lens gives you razor sharp,   real-time color video from a quarter-inch to infinity.   Our experiences...   --   We used our Flexcam for the first time yesterday and we were amazed!   We've replaced our bulky camcord that we use with P2P with the FlexCam   and we were able to have 5 of us in the picture at all times. What was   really amazing is the level of detail you can get when you point the   Flexcam down onto a coin or at a large open room. We really were   amazed that for �500 we could get such a high quality camera. We haven't   used the mics yet, but if they're even half the quality of the video   image, they'll be better than anything we have to date. We'll be using   the FlexCam for video conferencing or for showing foils, etc. when we   can't get the images online. Contact VideoLabs. Inc at : 5270 West 84th Street, Minneapolis, MN 55437, USA.

================================================================== Subject:Poor Still Pictures If you have problem with the quality of still pictures then consider the followings: - Ensure that the 'Enhanced Still' option ticked. - When you are happy with the image you have captured, select Save as     and where you see the ComboBox, 'Save file as type:', select 8 bit per pixel OS/2 bitmap. This means the image will show up better on the display. If you select 24 bit per pixel OS/2 bitmap, the package/app. that you use to display the image, should have the option to Halftone / Error Diffuse the image.

================================================================== Subject: Cannot get the following applications to be mirrored to P2P Chalkboard App 1:Micrografix ABC Flowcharter This is a Windows app. and currently P2P cannot mirror full-screen WIN-OS2 applications. App 2:Lotus 123 for OS/2, Version 2.0 When trired to mirror a Lotus spreadsheet into P2P chalkboard, doing s        brings down Lotus with the following error message:  SYS3175 A         program in this session encountered a problem and cannot continue. A program generated an access violation at 15e1e1e3. The solution is to add the following line to the CONFIG.SYS and reboot SET P2P_MIRROR_BUTTON=OFF or                 SET P2P_MIRROR_BUTTON=FLOAT For some reason, Lotus OS/2 apps all behave this way. This will prevent the chalkboard from trying to subclass the application frame to add the extra mirror icon and will cure the problem for both 123 and Freelance.

================================================================== Subject:WACOM Tablet Installed P2P (selected WACOM TABLET) and as a result, could not use IBM MOUSE but the WACOM TABLET is OK. What can I do? The WACOM tablet driver *replaces* the existing mouse driver. To support multiple pointing devices, you need Pen PM. Other 'solutions' require undocumented/unsupported features in MOUSE.SYS. Try OS2TABLT FORUM...  Or request the PenPM package? This will give all the required support. Look at PENPM_B FORUM for more details. Not only does this gives full TABLET support for OS/2 and can also use seamless Windows Apps. Also try: DEVICE=C:\OS2\MOUSE.SYS TYPE=IBMMOU* STYPE=TABMOU* *=dollar sign

================================================================== Subject:Types of UARTs in Your PC Under OS/2 simply type: MODE COMn: BUFFER It is highly recommended to enable extended buffering by simply typing: MODE COMn: BUFFER=ON  ..... where n comport number. Under Windows use MSD (or the IBM equivalent, eg:QCONFIG) for UART determination.

=
================================================================== Subject:16650 UARTS When high quality fast modems and high speed UARTS (16550A) used then use of P2P over modems is quite acceptable. Delays depend upon data far less than on P2P. P2P compresses that data before it is sent to the modem, all that is "missing" from P2P code is error correction but good quality modems will provide adequate error detection and correction. We recommend use of Modems with V42/V42bis.

================================================================== Subject: Video Freeze If video freezes for sometime (eg:5 to 20 seconds) while drawing/pasting on the Chalkboard, this may be due to: - Slow 386 SX machines - Lack of memory - Bridges between PCs - Ethernet networks get heavily loaded when the usage gets above 30%. - Video data has lower priority within P2P wrt Talk, FT, Clip and Chalkbroad data. Therefore if for example chalkboard is used (eg:free hand drawing) then obviously this higher priority data is transferred wrt video data. - Set compression to None in the communication sub-system panel.

================================================================== Subject: P2P video size Q1) What is the size and color capability of the captured video image?   ===== I think that I read somewhere that the size is 128 x 120 x         256 colors.  Can someone clarify this??? A1)  Here goes for a confusing answer ! The video is captured from AM-II as 128x120 pixel frames in YUV9 format. At first glance, this appears to suggest 512 colours but the card does fancy processing on the images and gives you a resulting image that looks pretty much like a 16 or 24 bit per pixel image (IMHO). Video sent to other AM-II users is compressed using the RTV algorithm then decompressed for display by the AM-II hardware in the receiving machine. The situation here becomes rather complex, however, since the displayed image does not look like 128x120 on your PM or Windows screen due to the fact that the AM-II mixes its video plane with VGA or XGA and that these 2 planes have different pixel sizes. Imagine 2 similarly sized sheets of squared paper with different square sizes overlaying one another. The top sheet represents the PM desktop and the bottom one the AM-II frame buffer. A block of squares drawn on the bottom sheet shines through to the top sheet but occupies a different number of squares at different coordinates from the top sheet viewer's perspective. (Does this help any ? It's difficult to explain without drawing a diagram. Call me on P2P if you are still confused). For a 128x120 (AM-II pixel) image, the perceived video image sizes (in desktop pixels) are below. The 2 values for AM-II resolution give the size of the whole "bottom sheet" depending upon whether or not you have checked the "High resolution" box in the display controls dialog. Remember that this "bottom sheet" represents the same physical screen area as the PM desktop (the "top sheet"). PM desktop  AM-II res    AM-II res    Apparent image size (PM pixels) (high)       (low)           (high)      (low) 640 x 480  512x480      256x240          160x120     320x240 1024 x 768  410x384      256x192          320x240     512x480 For example, with a VGA display showing AM-II video in low resolution mode, the 128x120 AM-II pixel image looks to the user like 320x240 VGA pixels (ie quarter screen). If using software video, the captured images are all 128x120 and use either 256 grey levels (if you select mono images) or 256 colours. These images are displayed using PM (or Windows GDI) and appear either as 128x120 PM or Windows pixels on the screen or stretched to fit the supplied video window. Q2) Is it possible to zoom the chalkboard so that a complete image can   be viewed    ===== It has been my experience that the size of the image you see         is less that the real image and is dependent upon the         resolution of the display.  My 8514/VGA appears to show about         25% of the total chalkboard capacity.  I can find no zoom         feature.  What is the size of the chalkboard in pels? A2)  There is no way of zooming in or out in the Chalkboard. In all cases, the chalkboard contents are shown pixel for pixel on all connected machines so if different resolutions are used on different machines in the same call, people see different percentages of the chalkboard area. The chalkboard scales dynamically as you use it so if you draw off the edge of the currently defined area, the chalkboard size increases to accommodate the new drawing. I'm not sure what the maximum size is but, on version 1.0 at least, it was enormous ! (Tip - don't zero the scroll bars on 1.0 and draw in the top left. Your machine is likely to page forever trying to allocate memory for an enormous image. This is fixed on 1.0.1 as far as I can see). If you get lost on a large chalkboard, Ctrl-Home moves your viewing position back to the centre and, if you are really desperate, someone else using the "sync" control will retransmit the chalkboard contents to you and move your viewing position to have the same centre as theirs.

============================================================= Subject:NETBIOS - Lack of Resources When a couple of people try to run Person To Person/2 off a LAN server, they get a message telling them that resources have run out Because of the large number of DLLs in P2P, each person running off the LAN places a load of about 25 file opens on the server. As the standard LAN server configuration only permits 64 file opens, they soon run out. Try increasing the number of file opens; a figure of 256 will let up to ten people access P2P, a couple of thousand will make the server logon limit the first barrier rather than the file open limit. Alternatively, get each user to install P2P for local use on their own disk and just make the site directory shareable. Doing this makes P2P faster as well.

================================================================== Subject:Jummy Video over LANs When I make a call that crosses a LAN bridge etc the video seems very jumpy and uneven. The solution is to do with frame rates. If the user is using a network with a slow link in it, for instance; imagine you have two users on separate LANS communicating over a slow bridge, then although you can set the P2P framerate as high as 15 frames per second, you will not necessarily get this. In fact what you will get is uneven video delivery. You might get a few frames quickly, followed by a wait of say a second. What I recommend the user do, is to estimate how many frames a second he is ACTUALLY getting on average, this can be done by counting how many he sees over say a minute, and reducing the framerate on P2P to this amount. At least then the video delivery will be even. An example is for ISDN; the ISDN maximum selectable framerate is about 2 frames a second but when you first install P2P, the default is about 1 frame a second.

================================================================== Subject: My ISDN calls seem to fail for no reason. This sort of thing can happen if you unplug the ISDN cable from the line. If a user running P2P is not in a call and for some reason tries unplugging then reinserting ISDN cables, it can cause problems if they then try to call someone. This is because the ISDN card may need reinitialising with the ISDN exchange. If they experience such problems, and calls are failing, they should restart P2P and try again. This problem occurs because we cannot detect when a cable has been removed, unless a call is in progress, in which case the call is dropped.

=
================================================================== Subject:Calculation of ActionMedia Frame Rate How can I calculate the ActionMedia II video frame rate that will be achieved given a particular link bandwidth or, conversely, how can I  calculate the bandwidth used by a given AM-II video rate ? In general, with low quality video selected in AM-II VSM config panel: 1 fps = approx 3.5KBps = 28Kbps This scales linearly with frame rate, so: bandwidth = approximately (28 * frame_rate) Kbps Note that this is for each video stream so the total bandwidth used will be twice this if, for example, 2 users are viewing each other. Using the above figures, the following values drop out: Max rate over ISDN (64Kbps full duplex channels)    = approx 2.3fps Async (9600 baud = 960 bytes per sec.) = approx 0.25fps Beware of bridged LANs or TCP/IP connections. In multi-hop communications situations, the maximum frame rate is governed by the minimum bandwidth link. Just because you are pumping out TCP/IP onto a 16Mbps Token Ring, there is no guarantee that one of the hops to the final destination is   not being carried at 110 baud over a piece of wet string ! Over a normal LAN, video rates on 486 machines are limited to 15fps (if   you have an NTSC camera) or 12.5 fps (PAL camera). Rates will drop back if running on a 386 machine (8fps is reasonable) or in a multiway call (where the frame rate depends upon many factors involving the machines   in the call and the network topology). If the high quality option is selected in AM-II configuration, then the frame size increases to around 5.5KB. The remaining calculations are left as an exercise to the reader !

================================================================== Subject: Problems with starting the chalkboard I just installed P2P/2 v1.02 on my mod 95. I'm a new user of P2P, and I'm noticing a problem when I try to start the chalkboard. Even though I have 24M of RAM and the hard drive where my SWAPPER file lives has 90M+ of free space, it seems like I still have to shut down practically every application that's open before starting the chalkboard in order for the chalkboard to start up successfully. In the cases where I don't, a couple of different things happen: after hearing a beep, I have to hit CNTRL-ESC repeatedly until I get a popup that says that Person to Person is not responding to system requests. After selecting ENTER to end it, I then see the popup that indicates that there were insufficient system resources (memory?) and to shut down some applications and try again. After clicking on OK, one of two things happen: either my desktop gets blown away and then comes back (the good case), or my desktop gets all hosed up (PM windows garbled, unable to access task list, etc.), and I have to reboot (obviously, the bad case). I'm using an Image Adapter/A with a 6091 monitor. Using an IA/A makes a huge difference ! In their wisdom, the writers of the original IA/A OS/2 drivers set a very low limit on the number of bitmap handles that the driver could cope with (I can be nasty since all these guys have now left IBM :-) ). In most cases, this limit doesn't pose a problem but the person who wrote the chalkboard decided to use up 49 (or was it 52 ?) bitmap handles, immediately blowing the IA/A driver out of the water. Although I can't be sure that this will work, you may like to try the latest version of 2.0 IA/A display driver. Well, I've got the 32-bit device driver installed, and P2P works *much* better. I kept all of my normal applications active, and had no problems at all starting up the chalkboard.

================================================================== Subject: What is H.320 and H.260 standard? H.320 is a hardware standard from the CCITT (now ITU or something ?) which defines audio/video/data (lip-synced) across ISDN lines and ensures interoperability between different suppliers video conferencing equipment (actually it doesn't since no-one thought to architect the protocols to be used on the data channel. Each manufacturer uses a different link layer packet protocol resulting in no-one talking data to anyone else - work is ongoing to sort this out, though - see T.12x proposals for more information). H.320 is a wrapper for several other standards - H.261 for video, H.221 for multiplexing onto ISDN channels, G.7xx for audio, etc... If you want to see H.320 in action with P2P for Windows v1.xx, take a look at the PictureTel Live-PCS100 system. This uses P2P software and their codec and gives an idea of the kind of thing to expect. Lakes (P2P v2.xx) will support H.320 audio/video with the BT VC8000 card (ScreenCall) though only in the UK under ISDN2.
