Part 1 – AT Commands for All Universal IP Devices

Chapter 5 – TCP AT Commands

#TCPPORT – Set TCP Port for Remote Peer

Description:

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

 

used for the TCP session.

Syntax:

AT#TCPPORT=id,<TCP Port number for remote peer value>

 

AT#TCPPORT=id Read or display the current setting (or AT#VTCP=id, AT#VALL).

id:

Enter a Profile Setting: 1 or 2 {1,2}

Values:

Set the value that the Profile will use:

 

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:

1

#TCPSERV – Set Address of Remote TCP Server

Description:

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.

Syntax:

AT#TCPSERV=id,"<Address of remote TCP server value>"

 

AT#TCPSERV=id Read or display the current setting (or AT#VTCP=id, or AT#VALL).

id:

Enter a Profile Setting: 1 or 2 {1,2}

Values:

Set the value that the Profile will use:

 

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.

#TCPTXDELAY – Time Delay

Description: This command determines the time delay introduced before sending a TCP frame that has not been entirely filled with user data. The time is entered in milliseconds, and it should be noted that a value of 0 initiates the sending of a TCP frame as soon as possible after the reception of a single character value from the host.

Syntax:

AT#TCPTXDELAY=id,<Time Delay value>

 

AT#TCPTXDELAY=id Read or display the current setting (or AT#VTCP=id or AT#VALL).

id:

Enter a Profile Setting: 1 or 2 {1,2}

Values:

Set the value that the Profile will use:

 

Integer multiple of 20 between 0 and 32760 inclusive.

Default:

0
