+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.
Syntax
+FIT=<time>,<action>
Defined Values
<time> The <time> 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.
<action> The <action> parameter has two meanings.
0 Upon timeout, the modem will go on-hook, executing an implied
ATH command; then reset to +FCLASS=0.
1 Upon timeout, the DCE will only go on-hook.
