U.S. Robotics I-modem Command Reference
Testing • Page 14-12
To use the test pattern during testing with S16, type the following command:
AT&M0S16=12
To use the test pattern with the &T test, insert the test pattern command, S16=4, before
issuing the test command:
ATS16=4&T6
The test pattern (ATS16=4) is used for testing equipment and the phone line. When S16 is
set to 4, the I-modem transmits the test pattern when it connects with a remote device.
Ending Testing That Uses the Test Pattern
Pressing any character key cancels all tests and hangs up the I-modem. If you used Regis-
ter S16, be sure to reset Register S16 and return to the error-control default. Send ATZ or
AT&M4S16=0.
