- Yep. From the faq: [pasted in directly from it]
-
- (21) Can I use COM3 and COM4 in OS/2?
-
- COM3 and COM4 are supported on most PS/2s without any additional effort.
- On (E)ISA machines, some additions are required to CONFIG.SYS. Using a
- text editor, include "(port number, base address, interrupt number)"
- parameters next to the COM.SYS and VCOM.SYS filenames. One example:
- DEVICE=C:\OS2\COM.SYS (3,3E8,5) (4,2E8,2)
- DEVICE=C:\OS2\MDOS\VCOM.SYS (3,3E8,5) (4,2E8,2)
- Parameters for COM1 and COM2 need not be included (unless they are
- somehow nonstandard). OS/2 must end up with sequentially numbered
- logical COM ports. For example, if (physical) port two is not installed
- but port three or port four is installed start numbering using (2,...)
- in the DEVICE lines. If these efforts fail, try IBM's patched COM
- drivers (available from sources listed in Question 8).
-
- Note that AT bus COM ports cannot be used at the same time if they share
- interrupts because of bus design limitations (cf. "Under the Hood: How
- Interrupts Work," Byte, February, 1992). PolyCom, a replacement driver
- available from sources listed in Question 8, supports up to eight ports
- with the right hardware.
