AT Commands: TCP
TCP
This group includes commands specific to TCP communications.
FIGURE 1. Common : TCP
S0=n
This register determines how the Raven X responds to an incoming TCP connection request. The Raven X remains in AT Command mode until a connection request is received. DTR must be asserted (S211=1 or &D0) and the Raven X must be set for a successful TCP connection. The Raven X 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=n
Specifies the number of seconds to wait for a TCP connection to be established when dialing out.
n=seconds
S60=n
Telnet Client Echo Mode.
n=0 : No Echo
n=1 : Local Echo (Default)
n=2 : Remote Echo
