- I have been trying for the past month to get my COM3 port to work using
- IRQ5. I have configured my I/O board for COM3,IRQ5,port 3E8. I also
- have the following lines in my CONFIG.SYS file:
-
- DEVICE=C:\OS2\MOUSE.SYS SERIAL=COM1
- DEVICE=C:\OS2\COM.SYS (3,3E8,05,p)
- DEVICE=C:\OS2\MDOS\VCOM.SYS
-
- I'm using the latest kernel patch and COM2210 drivers..
-
- Before installing the COM2210 drivers, OS/2 never saw COM3, no matter
- what I did. The COM.SYS parameters (as per the FAQ) didn't help.
- "touching" the port didn't help. Telix would see the port, but would
- loose characters even during initialization.
-
- With the COM2210 drivers, OS/2 sees COM3, I think.. using MODE, I
- can do a "mode com3" at any prompt, and it tells me all kinds of
- neat info about it.. but accessing the port with Telix (DOS) or
- PMComm (OS/2) results in the session hanging while the application
- tries to initialize.. (the modem ready light is light, but I can't send
- characters to the port).
-
- The comm program that came with OS/2 2.0 (PM Terminal)responds by saying
- that the port (COM3) is not available..
-
- I have checked to make sure that nothing else is using the COM3 address
- or IRQ5.. My computer has COM1 and COM2 build into the motherboard, and
- COM3 is on a multi I/O card. COM4 and LPT2 (both on I/O card) are
- both disabled until I get COM3 working. LPT1 is also on the motherboard.
-
- I'd appreciate any input on this. I do know this can be done.. I just can't
- figure out why it isn't working.
-
- My System:
- 386DX/16, 8MB RAM, Paradise Professional (running standard VGA),
- 210MB IDE drive, Everex I/O card (2S, 1P) with COM3 at 3E8,IRQ5
