PROBLEM DIAGNOSIS POSSIBLE SOLUTION
The computer or
software will not
recognize the
modem.
Your modem might not
be turned on.
You may not be entering
modem commands in
the proper manner while
in terminal mode.
You may have a COM
port/IRQ conflict.
Make sure the modem is turned on. The power switch is on top of external
modems. The CS light on the front panel should be lit. If you installed an
internal modem, it should power up when the computer is turned on.
When entering commands in a terminal program, type in all upper case (AT) or
all lower case (at).
WINDOWS 95 USERS: 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 below 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.
