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.
