S29 Flash Dial Modifier Time Default : 25
Sets the length of time, in units of 10 ms, that the modem will go on-
hook when it encounters the flash (!) dial modifier in the dial string. The
time can be limited as it is a country dependent parameter.
S30 Disconnect Inactivity timer Default : 0
Determines the length of time, in tenth of a second intervals, that the
modem will wait before disconnecting when no data is sent or received.
In MNP or V.42 mode, any data transmitted or received will reset the
timer. In other modes, any data transmitted will reset the timer. The
inactivity timer is incorporative in synchronous mode.
