Modem Installation
Use the following procedure to install your modem into an
IBM-compatible PC. Review the entire procedure before
beginning to install your modem, and do not remove the modem
from its protective anti-ESD (electrostatic discharge) bag until
you are ready to place it into your PC.

COM Port and IRQ Configuration

COM port configuration is often the cause of much confusion
when installing internal modems. Before attempting to install
your internal DataPort PCX modem, verify which COM ports are
available on your PC by running the COMTEST program
provided on the QuickLink II Fax diskette.
Select the diskette labeled QuickLink II Fax and insert it into
your floppy drive.
You can run the COMTEST program from DOS or Windows. To
run from DOS, type at the command prompt. To run from
Windows, select Run from the Program Manager File menu and
type in the Command Line window.
TYPE: a:\comtest (or b:\comtest if you
are using your b: drive)
PRESS: Enter (or Return)
The COMTEST program recommends COM port and IRQ
settings appropriate for your PC.
The DataPort PCX modem is shipped from the factory
configured for COM port 1 (COM1) and interrupt 4 (IRQ4). If
those settings are already in use in your computer, the
COMTEST program recommends different settings. Make a note
of the recommended settings so you can change the modem
switches before you install the modem.
