P—Select Pulse Dialing
Use this command to configure the modem for pulse dialing. All subsequent D<dial_string> commands
use pulse dialing until either the T command or a tone dial modifier is received by the modem. Tone dialing
is the default setting. This command does not use parameters and generates an ERROR result code when
parameters are attached to the command.
Q<value>—Result Code Control
Result codes are informational messages sent from the modem and displayed on the monitor. Basic result
codes include OK, CONNECT, RING, NO CARRIER, and ERROR. Use the Q<value> command to enable
or disable result code generation by the modem. If result codes are disabled and an invalid parameter
value is entered, the modem does not generate an ERROR result code because result codes are turn off.
Result codes:
• OK if <value> = 0—1.
ERROR if <value> ≠ 0—1.
