Initializing a Modem
Once flags, parameters and configurations have been enabled, the modem can be initialized
to accept incoming calls. This can be done in the following manner:
•
Place the System Key to Normal.
•
Issue a ps –ef|grep mirrord command.
•
Obtain mirrord process ID.
•
Issue a kill –9 <mirrord pid>.
•
Issue /usr/sbin/mirrord modemfilename.
•
Place the System Key into the Service position.
This initiates the mirrord process. The disconnect and condin parameters are read from the
appropriate modem file, and the modem is initialized for dial-in activity. After the mirrord
daemon is activated, the System Key should be placed in the Normal position.
Testing Dial-Out
Dial-out or automatic problem reporting can be tested from the SystemGuard Maintenance
Menu using the Offline Test for Dial-out. Successful connection and transmission of data
results in an OK completion.
During the test, the modem configuration file is read, the modem initialized properly, and
data transmitted. Comparing the modem configuration file to line activity shows disconnect,
condout, connect, transmit of data, disconnect and condin. Thus the modem is initialized for
dial-out, data is transmitted, and the modem is initialized to allow dial-in.
