TCP
CTSE Clear To Send Enable: This feature asserts CTS when there is a network
connection.
• n=0 : Disabled (Default).
• n=1 : Enable assertion of CTS when there is network coverage.
RS232 voltage levels:
• Positive = Network coverage.
• Negative = No coverage.
Flow control (AT\Q) will override this indication, so if you want to use CTS to
indicate network coverage, flow control has to be off (AT\Q0).
X
Extended Call Progress Result mode.
•n=0 : Turn off extended result codes (Default).
•n=1 : Turn on result codes. This adds the text 19200 to the
CONNECT response.
*NUMTIOP
Convert 12 digit number to IP.
•n=0 : Use as name.
•n=1 : Use as IP address.

Command Description
General
S0 This register determines how the device responds to an incoming TCP
connection request. The device remains in AT Command mode until a
connection request is received. DTR must be asserted (S211=1 or &D0) and
the device must be set for a successful TCP connection. The device will send
a “RING” string to the host. A “CONNECT” sent to the host indicates
acknowledgement of the connection request and the TCP session is
established.
• n=0 : Off (Default).
• n=1 : On.
• n=2 : Use Telnet server mode on TCP connections.
• n=3 : 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 Specifies the number of seconds to wait for a TCP connection to be
established when dialing out.
TCPT Interval to terminate a TCP connection when no in or outbound traffic. This
value affects only the TCP connection in TCP PAD mode.
• n=interval
