bits/s (default).

C—Carrier Control
This command is supported to ensure compatibility with communications software that issues the C1 command.
However, this modem does not support the C0 command. The C0 command instructs some modems not to send
carrier (i.e., it puts them in receive-only mode).
Result codes:
_
OK if = 1.
_
ERROR if ≠1.
Command Function
C1 Normal transmit carrier switching (default).
D—Dial
This command instructs the soft modem to go off-hook and begin the dialing sequence. The dial string (
string>, including modifiers and the telephone number) is entered after the D command.
A dial string can be up to sixty characters long. Any digit or symbol may be dialed as touchtone digits. Characters
such as spaces, hyphens, and parentheses are ignored by the modem and may be included in the dial string to
enhance readability.
