FIT - DTE Inactivity Timeout
This command specifies a DTE inactivity timeout value that allows the modem to break away from an unsuccessful
connection attempt at any stage of a facsimile transfer. The DTE inactivity timer operates only while the modem is off-hook.

parameter indicates the DTE inactivity timeout in seconds. The value of 0 indicates that
timeout is disabled (default). The required timeout range is 1 to 255 seconds. The inactivity timer
starts when the modem has taken some action that requires DTE response. If the DTE does
respond, the modem resets the inactivity timer. Inactivity timer related events are listed in Table 4-3.
