           DESCRIPTION

           USER PRODUCTIVITY

TCP/IP Version 1.2  has been designed  to improve the  productivity of
the end user.  There has been significant performance improvements  in
the entire product.  New  functions have been added to  TCP/IP Version
1.2 for OS/2, with the goal  of end user productivity in mind.   These
include the following:

  o Network File System (NFS) -- server

This allows users to  share files with each  other, much the same  way
that LAN Server/Requester works.  It also has the benefit of  allowing
a user with a UNIX machine to share files with an OS/2 machine.

           o   X Window System -- server

This is a distributed,  window-based graphics system developed  at the
Massachusetts Institute  of Technology.   TCP/IP  Version 1.2 supports
Version  11,  Release  4  (X11R4)  of  the  X  Window Server function.
Support for the X  Window System server for  OS/2 is an announced  IBM
Statement of Direction.

  o File Transfer Protocol -- Presentation Manager (TM) (FTPPM)

FTPPM uses standard presentation manager input and output  conventions
to  perform  the  functions  of  the  FTP  client.    It  also  allows
simultaneous connections to remote hosts within a single session.

  o Multi-Threaded Libraries

TCP/IP  Version  1.2  for  OS/2  supports the Multi-thread programming
feature of the OS/2 operating system in Socket libraries.

  o Dynamic Link Library Support

TCP/IP Version 1.2  for OS/2 supports  the dynamic linking  feature of
the OS/2 operating system.

(TM) Trademark of International Business Machines Corporation.

Many  functions  have  been  enhanced  to  provide  greater  end  user
productivity.  A list of these follows:

o Installation Configuration Automation  Tool (ICAT) has been  updated
to allow configuration of the new features of this program.  Also,  an
indicator displays how far along the installation has progressed.

o INETD is a  super server that allows  you to start multiple  servers
from a single OS/2 session, and use the applicable server when needed.

o TELNET Server has improved performance.

o TELNET LINEMODE Client Support is enhanced to take advantage of  the
Extended Networking package  that is new  to this program;  it reduces
the amount of network traffic for Extended Networking and SLIP.

o PMANT --  TN3270 has been  updated to allow  the user to  modify the
PMANT keyboard  definitions and  to select  from any  of the VIO fonts
that are available on the display adapter.

o File Transfer Protocol (FTP) will now support HPFS (High Performance
File System).   This  allows users  to transfer  files that  have file
names supported in HPFS.

o FTP API -- new procedures give programs the capability to query  the
working directory on a remote  host and query the operating  system of
the remote host.

o Simple Network Management Protocol  (SNMP) now supports MIB II  (RFC
1213).  The SNMP facility can now act as both a managing system and  a
managed system.

o LPR/LPD -- remote printer support

o Remote Procedure Call

o NFS Client.

           BUSINESS SOLUTIONS

TCP/IP Version 1.2 for OS/2  provides support for X.25 as  a transport
mechanism  thereby  providing  wide  area  networking  support  as  an
addition to the  overall business solutions  customers are seeking  in
their multivendor enterprises.

Support for the FTP/SMTP in Kanji is provided in passthru mode in this
release.

Support for the X Window System server Kanji fonts is provided in this
release.

The default  OS/2 Code  Page is  used to  support display  of National
Language Characters when  using VT200 TELNET  emulation.  The  default
OS/2 Code Page  for National Language  Support is also  available when
using FTP, TFTP, and SMTP.   INVESTMENT PROTECTION Many features  have
been added to TCP/IP Version  1.2 to protect the investment  customers
have  made  in  the  OS/2  workstations  they  are using in the TCP/IP
environment.  These include:

o Facilities for keyboard remapping in PMANT and TN3270

o Security enhancements to File Transfer Protocol (FTP)

o Security and Interoperability enhancements to NFS Client

o Remote Printer support in LPR/LPD

o Support of a TELNET LINEMODE client

o Support of Boot Protocol (BOOTP).

Also, the addition of such  functions as Dynamic Link Library  support
as  well  as  Multi-Threaded  Library  support  add  to  the   overall
investment  protection  provided  by  TCP/IP  Version  1.2 for OS/2 by
requiring less disk space and memory.

           GROWTH ENABLEMENT

Growth for  customers using  TCP/IP in  a multivendor  environment has
been  significantly  enhanced  by  the  following  additions to TCP/IP
Version 1.2 for OS/2:

o Support for OS/2 Standard Edition

o  Support  for  adapters  that  implement  a Network Device Interface
Specification (NDIS) Media Access Control (MAC) driver.

o Support of a Network File Server (NFS) Server

o Support of the X Window  System Server

o  Performance  File  System  as  part  of the FTP Client, FTP server,
FTPPM, and the FTP Application Programming Interface (FTPAPI).

           SYSTEMS MANAGEMENT

SystemView   (TM)   is   an   enterprise-wide  structure  for  systems
management.    The  term  systems  management  covers a broad range of
activities, from the daily operations that manage the resources of  an
information  system  to  the  long  range  planning that addresses the
future information processing needs of an enterprise.

The IBM  strategy for  systems management  consists of  the SystemView
structure and SystemView conforming products.

TCP/IP Version 1.2 for OS/2 provides support for systems management in
the  OS/2  environment.    The  network  management  protocol  support
provided  by  TCP/IP  for  OS/2  is Simple Network Management Protocol
(SNMP).

While TCP/IP Version 1.2 is not SystemView conformant, it provides key
features   that   apply   to   the  SystemView  application  dimension
discipline.  These features are as follows:

o Configuration Management

OS/2 TCP/IP provides  a Presentation Manager  based meters as  well as
its interface to the TCP/IP network.

o Performance Management

Key performance  related statistical  variables can  be obtained using
SNMP.

           o   Problem Management

The following problem management facilities are provided:

-  The  OS/2  TCP/IP  SNMP  Client  can  request the status of network
devices from SNMP agents on the network.

- The OS/2 TCP/IP  SNMP Agent TRAP support  will notify one (or  more)
SNMP Clients of significant network events.  These TRAPs include  cold
start and authentication failure.

- The TELNET Server capability  allows remote stations to logon  to an
OS/2 system,  providing remote  console capabilities  for full  screen
applications.  As  a problem determination  aid, this allows  a remote
support group to see what the remote end-user problem is.

- The Remote Execution capability  allows commands to be invoked  on a
remote system.   For  example, a  network manager  could start a trace
facility without involving the end user.

- The File Transfer Protocol allows remote support groups to  retrieve
a user's system  files, and after  inspection and correction,  replace
the original.

TCP/IP provides  the following  system management  enhancements in the
Version 1.2 for OS/2 product:

o Support of the new Management Information Base MIB II
o Ability to display SNMP TRAPs
o Ability to obtain the values of individual MIB variables
o Ability to verify the ability to reach a group of hosts.

o OS/2 Extended Edition Version 1.3
o OS/2 Standard Edition Version 1.3
o OS/2 Version 2.0.

Each of the optional function kits (such as NFS, Extended  Networking,
X Window System and the  Programmer's Toolkit) requires that the  base
kit be installed.

Additionally, the Source kit requires that the customer has  installed
the Programmer's Toolkit.

COMPATIBILITY:  TCP/IP Version 1.2  includes NDIS MAC drivers for  IBM
Token-Ring, IBM Ethernet and IBM PC Network adapters that do not  come
with NDIS MAC drivers.

NDIS  MAC  drivers  are  readily  obtainable  from  a  large number of
different vendors.

VT220 does not support downloadable fonts.

Special packaging is provided for upgrades from TCP/IP Version 1.0  or
Version 1.1 to TCP/IP Version  1.2 for OS/2.  This  packaging provides
all the function previously contained  in Version 1.0 or Version  1.1.
Refer to the ORDERING  INFORMATION section for specific  ordering part
numbers  and  feature  codes.    Proof  of  License for Version 1.0 or
Version 1.1 is required in order to upgrade to TCP/IP Version 1.2  for
OS/2.

           LIMITATIONS:

o Extended Networking (IP over  X.25) will execute on OS/2  EE Version
1.3.    However,  to  execute  on  OS/2  SE V1.3 or OS/2 2.0, the next
enhancement  to  OS/2   Communication  Manager  (when   available)  is
required.
