&Cn (CXR Control)
Determines how the modem handles CXR on the DTE
interface. Most computers operate with CXR set to
follow true carrier from the remote modem. Most
terminals operate with CXR forced on; some answer-
side host computers operate with the CXR port
contender option.

D
ESCRIPTION
&C0
CXR always on.
&C1*
CXR follows true carrier.
&Dn (DTR Control)
Determines how DTR is interpreted by the modem. &D
operates differently in asynchronous and synchronous
communication and also works in conjunction with
register S25 in asynchronous communication.
C
OMMAND
D
ESCRIPTION
&D0
In async mode, modem ignores DTR.
&D1
Modem switches to command mode when
DTR switches from on-to-off.
&D2*
When DTR switches on-to-off, the modem
goes on-hook and disables auto-answer
mode; when DTR switches off-to-on, auto-
answer is enabled.
&D3
Turning off DTR hangs up the on-line
modem and resets (ATZ) the modem to the
default stored profile.
