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.
