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.
When set at the default (0), the modem immediately hangs up when
DTR drops.
This option applies only to connections terminated by dropping DTR.
If the modem receives the ATH command, it ignores S38 and
immediately hangs up.
