Rem Digital Loop

This test is not available when using TMp modulation or Remote mode.

Rem Digital Loop performs a remote digital loopback (ITU-T V.54 Loop 2), Figure 8-2. This test can verify the integrity of the local modem, the communication link, and the remote modem. Any data or pattern entered at the local DTE is sent to and returned from the remote modem. For this test to operate properly, the modems must be operating at the same rate and in Synchronous or Asynchronous Direct mode.
