13.1 General Information on Troubleshooting
The cause of modem problems can often be found more easily by remembering
the two following points:
1. Activate the recording function for a log file for recording the data traffic
between the programming device/personal computer and the modem. The
entries in this file can provide valuable information for determining the cause of
errors.
2. Switch on the loudspeaker at your local modem. Select a volume which is loud
enough to be heard well.
You can then hear whether:
- There is a dial tone at the connection,
- The called modem is busy or
- The called modem accepts the call.
