Call Progress
Function and Description
The X command controls whether or not a busy signal or dial tone is detected when
dialing. The X command also limits the result codes the modem returns when dialing.
The operation of the X command is configurable for operation in different countries.
X0
X1
X2
X3
X4
The @ and W dial modifiers are not affected by the X command. The @ dial modifier
may return the result codes 8 (NO ANSWER) or 7 (BUSY) each time it appears in the
dial string. The W dial modifier may return the result codes 6 (NO DIALTONE) or 7
(BUSY) each time it appears in the dial string.
The #CID= command controls how the modem displays
North American caller identification information. The #CID=
command is valid only if the Modem Controller software has
been compiled to support Caller ID. If the software has not
been compiled to support Caller ID then the modem responds
with an ERROR result code to a #CID= command.
Caller Id information is displayed only when it is provided by
the telephone company, and only when the terminal data rate
is 2400 bps. Lower data rates are too slow to display the
Caller Id information.

#CID=1
#CID=2
