US Robotics Courier V.Everything - If You Are Using OS;2

6-4 Courier V.Everything Getting Started
Guide
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
package, visit the U.S. Robotics Totalservice web site at
http://totalservice.usr.com.
For Internal Couriers Only
These are the standard I/O address and IRQ settings for each COM port:
COM Port I/O Address IRQ
COM1 03F8 IRQ4
COM2 02F8 IRQ3
COM3 03E8 IRQ4
COM4 02E8 IRQ3
Nonstandard COM/IRQ settings are done by adding switches (command
line parameters) to the COM.SYS (or SIO.SYS) line in CONFIG.SYS.
For example, to select COM3 and IRQ5, enter the following command
line:
\OS2\BOOT\COM.SYS /i5/c3
