Dos; Os/2 - US Robotics Courier V.Everything 3CP3453 Getting Started Manual

DOS

Because there is no communication capability built in to DOS,
you must install and run a third-party communications software
package to operate the Courier.
You must choose the COM port, IRQ, and the I/O address
within the communications application that you are using.
These are the standard I/O address and IRQ settings for each
COM port:
COM Port
COM1
COM2
COM3
COM4
The Quick Link II diskette, which is included in the package
with the Courier, contains a DOS version of the software as well
as a Windows version.
For instructions about how to set up your DOS communications
software package, call our fax-on-demand service (at 800-762-
6163 or 847-676-1598) or our BBS (at 847-982-5092). Request
document 10000 for a list of our technical support documents.

OS/2

Remember that you can use WinOS2 to run Windows
communications software packages.
To get the best performance, however, you should replace the
standard OS/2 serial port drivers COM.SYS and VCOM.SYS
with SIO.SYS and VSIO.SYS. You can get the enhanced drivers
from our BBS at 847-982-5092. Check file area 18, OS/2 Support,
Utilities, etc for SIO153.ZIP.
