OK if <value> = 0 to 1
ERROR if <value> ≠ 0 to 1.
Return Online to Data Mode
Exits online command mode and enters online data mode. If the modem is not in
online command mode when this command is received, the modem generates an
ERROR result code.

CONNECT if <value> = 0, 1, 3 and result code and call progress monitor are set to 0
CONNECT <rate> if <value> = 0, 1, 3 and the result code and call progress monitor
NO CARRIER if the connection is not successfully resumed.
ERROR if <value> ≠ 0, 1, 3.
Set Pulse or Tone Dialing Default
Configures the modem for pulse (non-touch-tone) or Tone dialing. All subsequent
D<dial_string> commands use pulse dialing until either the T command or a tone

Modem performs handshake only at communication standard specified by S-
Register S37 and the B<value> command.
Modem begins handshake at communication standard specified by S-Register
S37 and command B. During handshake, fallback to a lower speed can occur.
Exits online command mode and returns to data mode.
