Well, I have used COM2 for communications with OS/2 1.1 before and
it worked.

I think your problem has to do with your Modem.  There are a lot of
"buggy" 8250 UART's in use, and OS/2 won't work correctly with these.
Try to buy a new UART (I suggest that you buy a 16550 FIFO UART if
you are going to change anyhow, you will get better performance) and
replace your 8250 UART.
