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.
