-
- In general, IRQ's are fixed in OS/2. The exception is COM.SYS. In your
- CONFIG.SYS, you can specify parameters to COM.SYS as follows:
-
- DEVICE=\OS2\COM.SYS (p,bbbb,i) (p,bbbb,i)
-
- where p = port number (1 for COM1, 2 for COM2, etc)
- bbbb = base port address (in hex). 03F8 for COM1, 02F8 for COM2, etc.
- i = irq for this port (4 for COM1, 3 for COM2, etc).
-
- The only time you have to specify these are if they deviate from standard.
- The replacement COM.SYS (available from friendly FTP sites everywhere) has
- additional parameters you can set to control buffering and timeouts. They're
- described in the COM package.
