Troubleshooting Modem Setup
Modem difficulties can usually be traced to interrupt, I/O address
or communications port conflicts. A modification to the Windows
NT 4.0 default communication drivers or physical damage to card
or cables can also be the source of problems.
Symptoms and Possible Causes
Windows NT fails to detect a Xircom modem. These conditions
can be caused by the lack of an available COM Port, or by a
resource conflict with another device.
Possible Solutions
1 Modify the interrupt and/or I/O address for the Xircom card
until no conflicts remain.
2 If your computer has an infrared communications port, disable
it. These ports often use COM port resources required for other
communications devices. Most infrared ports may be disabled
from within the computer’s CMOS or BIOS setup program. On
some computers a hardware setup utility is used. See your
computer documentation.
3 For difficulties in connecting to specific sites such as your
Internet Service Provider, or company remote access locations,
verify with the support personnel at the respective locations
that your client software and dial-in communications software
are configured properly.
