by register S12 (see S12°Escape Guard Time), the escape guard time.
Register S2 (see S2°AT Escape Character) identifies the escape sequence
character.
A/±Repeat Last Command
Use this command to repeat the last AT command. The modem repeats the
command currently in the command buffer. Do not use the AT prefix with
this command. Do not conclude the command with a terminating character
such as enter.
A±Answer
This command instructs the soft modem to go off-hook and answer an
incoming call.
B<value>±Communication Standard Setting
Use this command to select the communication standard used by the soft
modem.
B0
Selects CCITT V.22 mode when the modem is at 1200 bits/s.
B1
Selects Bell 212A when the modem is at 1200 bits/s (default).
B2
Deselects V.23 reverse channel (same as
B
3).
B3
Deselects V.23 reverse channel (same as
B
2).
B15
Selects V.21 when the modem is at 300 bits/s.
B16
Selects Bell 103J when the modem is at 300 bits/s (default).
C<value>±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).
C1
Normal transmit carrier switching (default).
D<dial string>±Dial
This command instructs the soft modem to go off-hook and begin the dialing
sequence. The dial string (<dial string>, including modifiers and the
