SERIES II INTELLIGENT DATA/FAX MODEMS
• If the power strip is on and the modem switch is on, try moving the
modem power supply to another outlet on the power strip.
• Test that the outlet is live by plugging a lamp into it.
• The modem or power supply may be defective. If you have another
Series II Modem, try swapping modems. If the problem goes away,
the first modem or power supply may be defective. Call Tech
Support for assistance.
CAUTION: Do not under any circumstances replace the power supply
module with one designed for another product, as it may damage the
modem and void your warranty.
The Modem Does Not Respond to Commands
• Make sure the modem is plugged in and turned on. (See “None of
the LEDs Light When the Modem Is On.”)
• Make sure you are issuing the modem commands from the data
communications software, either manually in terminal mode or au-
tomatically by configuring the software. (You cannot send com-
mands to the modem from the DOS prompt.)
• Make sure you are in terminal mode in your data communications
program, then type AT and press ENTER. If you get an OK re-
sponse, your connections are good and the problem likely is in
your phone book entry or session settings.
• Try resetting your modem by turning it off and on. Make sure there
is a reset command (&F) in your initialization string, or your
modem may not initialize correctly.
• If you don’t get an OK, the problem may still be in the communica-
tions software. Make sure you have done whatever is necessary in
your software to make a port connection. Not all communications
programs connect to the COM port automatically. Some connect
when the software loads and remain connected until the program
terminates. Others can disconnect without exiting the program
(make sure the Connect icon looks plugged in). If the terminal
reports that it cannot make a connection, yet the modem’s TR indi-
cator is on, click on the Window menu to see if more than one ter-
minal is open. The modem’s TR indicator shows that the software
has made a connection with the modem through the COM port.
