Register Default Function
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.
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.
