Call Waiting Enable
Controls the operation of the modem in the presence of call waiting.
+PCW0 Request modem-on-hold if enabled by +PMH and collect caller ID
information if enabled by +VRID. Toggle V.24 circuit 125. (Default.)

+PCW2 Ignore call waiting.
OK
ERROR
+PCW? Reports Selected Value(s).
+PCW=? Reports Supported Range of Parameter Values
Modem-on-Hold Enable
Controls the selection of modem-on-hold in the modem. The action of the modem
in response to modem-on-hold events is determined by the state of this command
as well as the state of a negotiated handshake with a V.92-compliant server in V.92
Mode.
+PMH0 Modem-on-hold enabled in V.92 Mode. (Default.)
+PMH1 Disabled modem-on-hold.
OK 0 or 1 in V.92 Mode (see the +MS command)
ERROR
+PMH? Reports Current or Selected Value.
+PMH=? Reports Supported Range of Parameter Values.
Initiate Modem-on-Hold
Requests the modem to initiate or to confirm a modem-on-hold procedure. The
modem will return ERROR if modem-on-hold is not enabled or if the modem is in
an idle condition. The modem will return the string response +PMHR: <value>
where <value> is a decimal value corresponding to the status of the modem's hold
exchange procedure as defined below. This response may be delayed depending
upon the context under which the +PMHR command is made, i.e., if the +PMHR is
in response to an incoming modem-on-hold or if it is initiating a request.
Note: If modem-on-hold is enabled but the remote server does not support V.92
then the modem will always report 0 to show that the hold request is denied.
+PMHR:<value>
The value corresponds to the maximum hold time the server or hold-granting
modem will allow.
+PMHR0 V.92 MOH request denied or not available.
+PMHR1 MOH with 10-second timeout Granted.
+PMHR2 MOH with 20-second timeout Granted.
+PMHR3 MOH with 30-second timeout Granted.
+PMHR4 MOH with 40-second timeout Granted.
+PMHR5 MOH with 1-minute timeout Granted.
+PMHR6 MOH with 2-minute timeout Granted.
+PMHR7 MOH with 3-minute timeout Granted.
