Recall stored profile

The modem performs a soft reset and restores (recalls) the
configuration profile according to the parameter supplied. If no
parameter is specified, zero is assumed. Either Z0 or Z1 restores
the profile.
Result Codes:
OK

n=0,1

ERROR Otherwise

&Cn Data Carrier Detect (DCD) control

Data Carrier Detect is a signal from the modem to the computer
indicating that a carrier signal is being received from a remote
modem. DCD normally turns off when the modem no longer
detects the carrier signal.
&C0

The state of the carrier from the remote modem is
ignored. DCD circuit is always on.

&C1

DCD turns on when the remote modem’s carrier signal
is detected, and off when the carrier signal is not
detected (default).

Result Codes:
OK

n=0,1

ERROR Otherwise

&Dn DTR control

This command interprets how the modem responds to the state
of the DTR signal and changes to the DTR signal.
&D0

Ignore. The modem ignores the true status of DTR and
treats it as always on. This should only be used if your
communication software does not provide DTR to the
modem

&D1

If the DTR signal is not detected while in on-line data
mode, the modem enters command mode, issues an
OK result code, and remains connected.

&D2

If the DTR signal is not detected while in on-line data
mode, the modem disconnects (default).

&D3

Reset on the on-to-off DTR transition.

Result Codes:
OK

n=0,1,2,3

ERROR Otherwise
