Register Default Function
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.
S41 0 Bit-mapped register setup. To set registers, see instructions for S13.
