Recovering Asynchronous Terminal Operation

If the DSU/CSU is misconfigured, leaving it in a state that does not support
asynchronous terminal operation, use the following recovery procedure.

Procedure

1. Power cycle the DSU/CSU, waiting for the completion of the power-on

self-test.

2. Press the asynchronous terminal’s Return key five times in succession.

(Begin pressing the Return key within two seconds after the completion of
power-on self-test, and do not wait longer than one second between each
successive key press.)

3. The System Paused screen appears. Use it to reset the COM port

configuration options or to reload all factory default configuration options.
