Hi Doug,
To try and get the GTCO CalComp DrawingBoard IV working as a mouse on eComStation start as follows:
You need to use the optional serial interface. You need to customize the tablet data format and communications parameters using the Menu Strip.
Mode: Run. Baud Rate: 38400. Data Bits: 8. Parity: None. Data Rate: 125 pps. Resolution: 2540 lpi. Output Format: 21. Emulation: Wacom Binary.
Using the above values I expect the tablet to interface the same way as the Lenovo ThinkPad (COM) models do.
Add DEVICE=O:\OS2\BOOT\PSCOM.SYS into your O:\CONFIG.SYS file assuming eComStation installed on drive O:
Reboot your system and run "COMRAW.CMD" to get raw input data. Run "DECODE.CMD" to display events.
Display from DECODE.CMD using the correct baudrate looks like:
sBtn=00,xPos=03799,yPos=02328,zPos=00026,Stylus:MoveOnly
sBtn=01,xPos=01789,yPos=03436,zPos=01418,Stylus:But1Down
sBtn=00,xPos=01794,yPos=03433,zPos=00016,Stylus:MoveOnly
sBtn=00,xPos=00010,yPos=00027,zPos=00024,Stylus:NoButMov
Regards, Wim.
