- Many have this kind of problem. Some "solutions"
-
- 1. The commga (2210?) drivers were reportedly better at finding ports.
- Unfortunately, they had other problems which I've forgotten.
-
- 2. Some folks (like me) can "touch" their port, then ctrl-alt-del. Someone
- suggestd touching from dos (with procomm? echo > com3 ?), then re-boot and
- OS/2 recognizes the port.
-
- I used the com16[45]0.sys drivers (originally designed to bring com3 to OS/2
- 1.3). These work as my com driver in OS/2 (didn't test dos-boxes). I can
- also remove these lines from my config.sys, put the usual lines back in, and
- ctrl-alt-del. Everything works, until the next power off-on.
-
- 3. Some folks want to use IRQ4 with com3 and com1 (but not use both ports at
- the same time). It has been reported that the "IRQ not available" message
- can be avoided by giving OS/2 some other IRQ number for com1 (the post said
- to use the same IRQ as used by the mouse). NOTE: I am not saying that this
- gives use of both ports com1 and com3.
-
- com16[45]0.sys can be found at ftp-os2.nmsu.edu in pub/os2/1.x/sysutils/, if
- I recall correctly.
