+PMHR - Initiate Modem-on-Hold
This command 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.
