Modem Test Procedures

This test checks the path between the local Modem and the PC. The test
is only functional when the Modem is in direct mode (&Q0) and the COM
port baud rate is set to 14400 bps (Trumpcard 14400) / 28800 bps
(Trumpcard 28800) or less.

To start this test, the Modem must be in command mode.

To run this test:

1. Enter 

AT&T1 [ENTER]

. Wait until the Modem returns a 

CONNECT

message.

2. Enter a test message. For example, 

“This message should be

echoed back.”

The message should immediately appear on the screen as you enter

it.

3. Enter 

+++

 (the escape sequence).

The Modem will respond with 

OK

. The Modem is now in command

mode.

4. Enter

 AT&T0 [ENTER]

 to end the test.
