11-08-1995 14:49:49.40 - Received DLE Raw=117, Translated=255.
DLE received from modem. The Raw value is the actual value received, and the Translated value is the value Unimodem has mapped it to. See the DLE translation table in Interpreting Modem Event Logs. In this example, the DLE is translated to 255, which means that Unimodem/V ignores this DLE.

Interpreting Modem Event Logs
Two sample modem event logs produced by LOGWIN.EXE are shown in the following, one for a data modem session and the other for a voice modem session. In order to interpret the event logs, you need to understand the following about how LOGWIN.EXE and Unimodem/V work together to produce the logs.
When Unimodem/V receives a DLE from the modem, the DLE is translated to a standard event. Following is the table that maps the translated value to the event. The modem log displays the actual DLE received and it's translated value.
