Configuring the Communication Software
While some expansion slot adapters and built-in COM ports can
share IRQs, PC Cards cannot share IRQs. To avoid sharing IRQs,
the IRQ assigned to your modem by Card and Socket Services may
be set differently than Windows and the communication software
expects. You may have to re-configure the software as follows:
1.
Refer to the documentation that came with Card and
Socket Services, and determine the COM port and IRQ
that Card and Socket Services assigns to your modem.
2.
You may have to edit the SYSTEM.INI file of Win-
dows. Before editing SYSTEM.INI, make a backup of
SYSTEM.INI.
Open SYSTEM.INI with your favorite editor. Find the
same COM port that your modem uses as determined in
Step 1. Then change the IRQ associated with that COM
port so that it is the same as that determined in Step 1.
Save the new SYSTEM.INI, then restart Windows.
3.
Next, refer to the guide included with the communication
software and make sure your the communication software
is set to the same COM port and IRQ as determined in
Step 1.
Installation is complete. Proceed to Chapter 4.
