Diagnosis:
You may have a COM port/IRQ conflict.
Possible Solutions:
If you are using an internal modem on a
Windows 95 system: Uninstall the modem
from your computer. In Device Manager,
determine what COM port and IRQ settings
are free on your system. Set the jumper
shunts on your modem’s jumper pins to these
free settings, using the diagrams on the right
as a guide. If no IRQ setting is available, you
may need to move a device off of an IRQ in
order to free it for use by your modem.

in the Windows Device Manager.
PROBLEM:
The modem displays double
characters on your monitor.
Diagnosis:
The software’s local echo setting is probably
turned on.
