Register Default Function
S38 0 Sets an optional delay, in seconds, before a forced hang-up and clearing of the
Transmit buffer when DTR drops during an ARQ call. This allows time for a
remote modem to acknowledge receipt of all transmitted data before it is
disconnected. The modem immediately hangs up when DTR drops. This option
only applies to connections terminated by dropping DTR. If the modem receives the
ATH command, it ignores S38 and immediately hangs up.
