Reserved.
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.
