DIAGNOSTICS
This programming section is used to initiate test processes and provide
valuable information for troubleshooting any problems. All tests are normally
run from the Local/Maintenance Port but some may be run remotely via the
Modem Port.
The most valuable test to use is the PORT LOOPBACK TEST. When an RS-
232 cable is connected from the Modem Port to a User Port, the DS-100 will
exercise that port to verify proper operation of the User Port (and cable).
The CONTROL LEAD CHECK will test the status of the Control Leads for a
particular port. Control Leads tested include:
DTR
