This register determines how the Raven responds to an
incoming TCP connection request. The Raven remains
in AT Command mode until a connection request is
received. DTR must be asserted (S211=1 or &D0) and
the Raven must be set for a successful TCP connection.
The modem will send a "RING" string to the host. A
"CONNECT" sent to the host indicates acknowledge-
ment of the connection request and the TCP session is
established.
Off (Default)
On
Use Telnet server mode on TCP connections
With a Telnet connection, overrides the client's default
echo, allowing the server on the host port to perform the
echo. CRLF sequences from the telnet client will also be
edited to simply pass CRs to the server on the host port.
S7=n n = seconds Specifies the number of seconds to wait for a TCP con-
nection to be established when dialing out.

Ex. ATS23=19200,8N1 (sets modem to 19200, etc.)
The settings take affect after reset.
Note: MUST be 8 data bits for PPP mode.

S50=n n = tenths of
seconds Data forwarding idle time-out. If set to 0, a forwarding
time-out of 10ms is used.
