MODEM STATUS CODES IN V.34 PROTOCOL DUMP
6.2 MODEM STATUS CODES IN V.34 PROTOCOL DUMP
The following sections explain the meaning of modem status codes which appear
on the G3 protocol dump list after V.34 communications.
NOTE: 1) The machine sometimes cannot print all the status codes.
For example, even if code 0127 (INFOh reception) is not printed, the
modem may actually have received INFOh.
2) In polling, the signals go in the opposite direction after phase 2. Also,
INFO0c replaces INFO0a, and vice versa.
