S35-S37 Reserved.

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.
