2400 BPS External Modem (250-3026)  Testing The Modem  Faxback Doc. # 5036

Power Up and Installation Testing:

Flip the power switch on your modem to the On position. The MR (Modem Ready) 
light should come on. Depending on various modem settings and factors exter-
nal to the modem, other lights may also be on.

When you first turn on the modem, it automatically performs a self-test to 
verify that it is functioning properly. This test operates in the "analog 
loopback mode" using internally generated test patterns. If an error is 
found, it will send an error message to the monitor the first time it is 
used.

Running a Brief Modem Test:

To confirm that your modem is communicating with your computer, you can 
perform the following test:

Run your communications software in "terminal", "local", or "dumb" mode. In 
many programs this is the mode entered when the program starts. Type AT and 
press ENTER. You should see:  AT  OK
