Initialize Parameter: This command causes the modem to initialize all voice pa-
rameters to the factory default values. This command does not change relay or
speaker setup (that is, if the modem is off-hook, then the modem remains off
hook after processing this command).

DTE / DCE Inactivity Timer: This command sets the length of time the modem
can be inactive in voice mode before the modem resets its relays +VLS=0 and
changes to data mode (FCLASS=0) with autobauding. The purpose of this timer
is to ensure that the DTE does not leave the DCE in a mode that cannot be ac-
cessed by voice-unaware software. This timer is supported in playback, record
and voice command mode. Sending any data (such as a <DLE><NUL> string) to
the modem re-initializes this timer.
n =0–255 (units of 1.0 second)
n = 0* Disables inactivity timer
n ≠ 0 Inactivity timer active
