Cabletron Systems CSMIM-T1 manual En Compromise Equalizer, En Data Echo, E0, Mode

Chapter 7: AT Commands and Registers

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.

:En 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.

\En	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.

%Fn	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.

NOTE

Entering AT%Fn (n=1, 2, or 3) disables all protocols except V.23. Entering AT%Bn forces the %F0 setting.

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.
