%C3
V.42 bis/ MNP 5 enabled. Data compression enabled (default).
%E<value>±Auto Fallback/Fallforward Control
This command provides the option for the modem to automatically monitor
line quality, to fall back when line quality is insufficient, and to fall forward
when line quality is sufficient.
%E0
Disables fallback/fallforward.
%E1
Enables fallback and disable fallfor-ward.

Enables fallback/fallforward (default).
-C<value>±Data Calling Tone
Use this command to enable or disable the data calling tone after a call is
originated. The data calling tone is a tone of a certain frequency and cadence
as specified in V.25 which allows remote data/FAX/voice discrimination.
The frequency is 1300 Hz with a cadence of 0.5 s on and 2.0 s off.
