number of sequential data frames that may be
outstanding (not acknowledged) at any given time.
Valid range is 1-127 frames. Default: 7.
AT!E4=n V.120 T200 (Retransmission Timer): Applicable to
the multiframe mode only. T200 (Retransmission
Timer) is the maximum time allowed to determine if a
transmitted frame was received by the remote device,
prior to its retransmission. The unit of measurement is
1/10 seconds. Valid range is 1-255. Default: 15 (equal
to 1.5 second).
The value specified for T200 (Retransmission Timer)
must be less than the value specified for T203 (Link

retransmissions is reached, the recovery process is
started which may cause call disconnection.
