Chapter 5 - TCP Socket Services

Parameter Definitions

#DLEMODE Set DLE Mode

Definition: When using socket TCP, the attached host has the choice whether or not to code the ETX character.

Values: 0 When DLEMODE is set to 0, no specific process is needed on [ETX] characters.

It means that it is not possible for a host to request an end of connection or to receive a clear

indication of the end of a connection from the TCP/IP stack.

1 When DLEMODE is set to 1, the [ETX] character means a request or an indication of end of

connection.

As a consequence, [ETX] characters that belong to the payload data must be sent by the host on

the serial port preceded by a DLE character. Similarly, ETX characters received by the TCP/IP

stack from the Internet are sent to the host through the serial port preceded by a DLE character.

Default.

id: {1,2}

Syntax: Set Value: AT#DLEMODE=id,<value>

Get Value: AT#DLEMODE=id or AT#VTCP=id, AT#VALL

#TCPPORT Set TCP Port for Remote Peer

Definition: To exchange data over TCP, the TCP/IP stack software must know the port of the remote peer used for

the TCP session.

Values: From 1 to 5 digits (each digit between 0 and 9 inclusive). Note that numbers above 65,535 are illegal as

the port identification fields are 16 bits long in the TCP header. Default 0.

id: {1,2}

Syntax: Set Value: AT#TCPPORT=id,<value>

Get Value: AT#TCPPORT=id or AT#VTCP, AT#VALL

#TCPSERV Set Address of Remote TCP Server

Definition: To exchange data over TCP, the TCP/IP stack software must know the address of the remote TCP

server (or host) that is to be used.

Values: 32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx) or

Alphanumeric ASCII text string up to 120 characters if DNS is integrated. No default.

id: {1,2}

Syntax: Set Value: AT#TCPSERV=id,value>

Get Value: AT#TCPSERV=id or AT#VTCP, AT#VALL

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 ... 77 78
