:E
n
Compromise Equalizer
:E0
Disables the compromise equalizer only when the modem is in
V.32bis or V.32 mode; may be useful for direct line connections
or PBX-to-PBX connections.
:E1
Enables the compromise equalizer; may be useful for
outside-line-to-outside-line or PBX-to-outside-line connections.
Controls equalization operation in V.32bis or V.32.
\E
n
Data Echo
\E0
Does not echo data sent by the local computer.
\E1
Echoes data sent by the local computer.
When operating in connect state, determines whether the modem
echoes characters sent from the local computer. \E1 functions
only during normal mode connections.
%F
n
V.23 Mode
%F0
Allows multi-protocol answering; disables V.23 mode on
originate modem.
%F3
1,200 bps transmit, 1,200 bps receive (half-duplex) V.23 mode.
Detemines the V.23 mode used at 1,200 bps.
When %F0 is set and the modem is at 1,200 bps or higher, it can
answer as a V.23 1,200/1,200 bps half-duplex modem.
When %F3 is set, the modem can only establish normal or direct
1,200 bps half-duplex connections.
The \S command shows MODEM BPS V.23 AT when the
modem establishes V.23 connections.
NOTE
The modems will not be able to pass data when a reliable
connection (\N3 or \N5 is set) falls back to a normal connection
with 11-bit data characters enabled on both modems.
NOTE
Entering AT%Fn (n=1, 2, or 3) disables all protocols except
V.23. Entering AT%Bn forces the %F0 setting.
