RealPort Ethernet 10/100+Modem 56 User’s Guide
Symptoms and Possible Causes
Windows NT or the Xircom CountrySelect software fails to detect a
Xircom modem. These conditions can be caused by the lack of an
available COM Port, by a resource conflict with another device, or
by use of the wrong modem INF file during the installation.
Possible Solutions
1
Use the steps under Troubleshooting Network Installation to
modify the interrupt and/or memory address for the Xircom
card until no conflicts are reported.
2
If your computer has an infrared communications port, disable
it. These ports often use COM port resources required for other
devices. Most infrared ports may be disabled from within the
computer’s CMOS or BIOS setup program, or with a hardware
setup utility is used. See your computer documentation.
3
It is possible, though unlikely, that the computer may not have
an available COM port for the modem. You may need to
disable a COM port device to free a port for the modem. Before
you attempt this, consult the computer hardware manufacturer
for information on the possible consequences.
4
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.
