C,D
Min TX rate/Max TX rate are optional numeric values that specify the lowest value
at which the DCE may establish a connection. If unspecified (set to 0), they are
determined by the carrier and automode settings.
E,F
Min RX rate/Max RX rate are optional numeric values which specify the highest
value at which the DCE may establish a connection. If unspecified (set to 0), they
are determined by the carrier and automode settings.
+PCW = X
Controls the action to be taken upon detection of call waiting.
X
Mode
0
Toggle RI and collect type II Caller ID if enabled by +VCID.
1
Hang up.
2
Ignore call waiting.
+PIG=X
Controls the use of PCM upstream in a V.92 DCE.
X
Mode
0
Enable PCM upstream.
1
Disable PCM upstream.
+PMH=X
Controls the modem-on-hold procedures.
X
Mode
0
Enables V.92 MOH.
1
Disables V.92 MOH.
+PMHF=X
V.92 MOH hook flash. This command causes the DCE to go on-hook and then return off-
hook. If this command is initiated and the modem is not On Hold, Error is returned.
