Sets dialing mode to pulse.
Selects the result code transmission.
n = 0: Result code is transmitted.
n = 1: Result code is not transmitted.
Sets the pointer value for S resistor to “r”.
Echoes back the content of S resistor specified by “r”.
Sets the content of S resistor specified by “r” to “d’.
Sets dialing mode to DTMF.
Selects the type of result code.
n = 0: Number
n = 1: Characters
Selects the extended result code and call progress tone
detection.
Reset in the same way the PDN/RST pin is set to “0”.
Controls data carrier detection signals (DCD).
n = 0: Always sets DCD to ON.
n = 1: Controls DCD by detecting reception carriers.
Controls the modem in DTR signal state.
n = 0: Ignores DTR signals.
n = 1: Ignores DTR signals. In data mode, however, moves
to on-line command mode when DTR signals change from
ON to OFF
n = 2, 3: Goes to command mode after disconnecting lines
when the change of DTR from ON to OFF is detected during
communication.
Sets the guard tone transmission.
n = 0: No guard tone
n = 1: With guard tone of 550 Hz
n = 2: With guard tone of 1800 Hz
Selects the make rates of pulse dialing.
n = 0: 39% (10 pps)
n = 1: 33% (10 pps)
n = 2: 33% (20 pps)
