&Cn

LSD Control

&C0

Forced On. Forces LSD ON at all times.

&C1

Standard RS232. LSD is ON when the
remote modem’s carrier signal is
detected.  LSD is Off when carrier
signal is not detected.

&C2

Wink When Disc. LSD, normally forced
ON, turns Off for approximately 1 to 2
seconds upon disconnect.

&C3

Follows DTR. State of LSD follows state
of DTR.

&C4

Simulated Control Carrier.  State of LSD
follows state of remote modem’s RTS.

&C5

=DTR/DiscOff.  State of LSD follows
state of DTR except upon a disconnect
where DTR remains ON and LSD turns
Off.  DTR must then toggle Off and ON to
turn LSD ON. Required for AT&T
DATAKIT

 dial-out applications.

&C6

Bridge Retrain. LSD behaves as in
Standard RS232, except that it is turned
Off when retrain lasts longer than 10
seconds, and ON when no retrain is
detected for 10 seconds.

&Dn

DTR Action

&D0

Ignore. Modem ignores the DTR (Data
Terminal Ready) signal and treats it as
always ON.

&D1

Off=Command Mode. Modem enters
online Command mode when DTR is
lowered.

&D2

Standard RS232. DTR signal is

area when DTR is lowered.

&D4

Controls On-Hook. Modem does not
disconnect until DTR lowered by DTE.
