11.3.8 P779 Modem idle time
Sets the time in seconds that the BW500 and BW500/L will keep the modem connected even
though no activity is happening.
To use this parameter ensure that P778=1.
This parameter allows for reconnection to the BW500 and BW500/L unit after an unexpected
disconnect. Ensure that the value is low enough to avoid unnecessary delays when an
unexpected disconnect occurs but long enough to avoid timeout while you are still legitimately
connected.
Hanging Up
If the line is idle and the P779 Modem Inactivity Timeout expires then the modem is directed to
hang up the line. This is done with the Hayes commands:
● two second delay
● +++
● two second delay
● ATH
Ensure that P779 is set longer than the standard polling time of the connected master device.
0 disables the inactivity timer.
