If You Are Using OS/2

Replace the standard OS/2 serial port drivers COM.SYS and VCOM.SYS
with SIO.SYS and VSIO.SYS. You can get these enhanced drivers from the
U.S. Robotics web site.
For instructions about how to set up your OS/2 communications software

These are the standard I/O address and IRQ settings for each COM port:

For example, to select COM3 and IRQ5, enter the following command
line:
