PCI Modem Card User's Manual +PMH=-Modem On Hold Enable Use this command to enable or disable modem on hold. Note, that the +PMH command does not effect the parameters of the +PMHT command. The +PMH command only enables or disables modem on hold. The +PMHT command configures the modem to deny a modem on hold request or grant a modem on hold request with the selected hold time. +PMH=0 Enables modem on hold (default). +PMH=1 Disables modem on hold. +PMHF-Modem On Hold Hook Flash Use this command to generate a hook flash during modem on hold operations. The command causes the modem to go on-hook for a period of time set by S29. Then the modem returns to the off-hook state for at least 1.5 s. +PMHR-Initiate Modem On Hold Use this command to initiate a modem on hold request. Once the local modem receives this request from the user or controlling application, the soft modem requests that the remote modem go on hold. The remote modem either denies the request or grants the request. If the request is granted, the remote modem initialized the modem on hold timer and informs the local modem what the length of the hold duration is. If the request is denied, the local modem generates an ERROR result code and hangs up the line. +PMHT=-Modem On Hold Timer Use this command to configure the soft modem to grant or reject a modem on hold request. This command configures the modem so it can respond to a modem on hold request. The command must be executed prior to reception of a modem on hold request. If a modem on hold request is made prior to execution of the +PMHT command, by default, the modem on hold request is denied. This command also sets the modem on hold timer. The modem on hold timer sets the amount of time the modem will remain on hold waiting for the requesting modem to return to the line. If the timer expires, the soft modem will hang up the call. +PMHT=0 +PMHT=1 +PMHT=2 +PMHT=3 +PMHT=4 +PMHT=5 Deny modem on hold request (default). Grant modem on hold request with a 10 s time-out. Grant modem on hold request with a 20 s time-out. Grant modem on hold request with a 30 s time-out. Grant modem on hold request with a 40 s time-out. Grant modem on hold request with a 1 min. time-out. 58
