Pattern

Pattern can transmit and receive a 511 bit error rate test

pattern. It can also be used with a local analog loopback
or a remote digital loopback to simulate data passing
through the modem. For this test to operate properly, the
modems must be online and in Synchronous or
Asynchronous Direct mode. Otherwise, the message
Invalid:Bffr Mde appears when this test is started.
(See Figures 7-4 through 7-6.)
