an &T0 or H command.
S24 — Sleep Inactivity Timer
Range
Default
Sets the length of time, in seconds, that the modem will wait before
entering power down sleep mode. The time is reset by any data activity or
telephone line activity. A value of zero will disable power down sleep
mode.
S25 — Delay to DTR
Range
Default
A change in /DTR (ON-to-OFF) that persists for a period shorter than the
value held in S25 is ignored by the modem while it is in data mode.

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
