Toshiba M200 User Manual

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

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

Result Codes:

n=0,1

Otherwise

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

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

If the DTR signal is not detected while in on-line data mode,
the modem enters command mode, issues an 

result code,

and remains connected.

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

Reset on the on-to-off DTR transition.

Result Codes:

n=0,1,2,3

Otherwise

This command loads the configuration stored and programmed at the
factory. This operation replaces all of the command options and the S-
register settings in the active configuration with factory values.

Recall factory setting as active configuration.
