E-6 Modem Testing
&T6
1 Set the software to 2400 bps or lower. Set the modem to &M0.
If you wish, set the S18 timer.
Establish a connection with the remote modem. If you haven't
already done so, arrange with the remote user to cooperate
with your testing and, if necessary, set the remote modem to
acknowledge the RDL request. For example, older U.S.
Robotics high speed modems need to be set to S16=8.
2 Bring the Modem back to Command mode with the +++ escape
code. Send it the AT&T6 command. The modem enters RDL
mode and the Modem LED glows green.
3 Type a short message. It will be looped back to your modem
by the remote modem and to your screen for verification. (The
remote user will not see your data.)
4 End the test. If you set Register S18 the modem automatically
ends the test when the test timeout is reached. If you didn't set
S18, type AT&T0 to end the test. Or send either ATH or the
command that resets the modem, ATZ. The latter two
commands end the test and hang up the modem. The modem
responds OK.
Data errors indicate a problem with the remote modem or the
phone link. If you have not performed analog loopback testing
with your modem, the problem may also lie with your modem.
5
Reset D IP switch 9 OFF unless you normally set that switch
ON, and issue ATZ to the modem to initiate the new setting.
Reset the modem to &M4 unless you used the reset command,
ATZ.
&T7
This test option causes the modem to send an internal test pattern
through the Remote Digital Loopback. An internal error detector
counts any errors and, when the test is ended, sends the number of
errors or 000 (no errors) to the screen.
You don't need to type anything during this test. The modem
sends only its final error count to your screen.
1 Set the software to 2400 bps or lower. Set the modem to &M0.
If you wish, set the S18 timer.
