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.

subsequent D<dial string> commands use

the modem. Tone dialing is the

ERROR result code when parameters
are attached to the command.
