Part 1 – AT Commands for All Universal IP Devices

Universal IP AT Commands Reference Guide 35

Use these AT commands with any Universal IP device.

Set Commands

The id parameter is used for setting up profiles; Profile 1 and Profile 2. To view parameters including profile

settings, use AT#<cmd>=id or AT#VTCP=id or AT#VALL.

#PERSISTENTSOCKET - Persistent Socket

Description: If enabled and the physical connection is present, a socket will be created automatically.

Syntax: AT#PERSISTENTSOCKET=<Persistentsocket value>,<Result Codes>

AT#PERSISTENTSOCKET? Read or display the current setting (or AT#VALL).

Values: 0 – Persistent socket is disabled

1 – The TCP originate is started (#OTCP=1)

2 – The TCP listener is started (#LTCPSTART=1)

3 – The UDP originate is started (#OUDP=1)

4 – The UDP listener is started (#LUDPSTART=1)

5 – The TCP originate is started (#OTCP=2)

6 – The TCP originate is started (#LTCPSTART=2)

Result Codes: 0 – All result codes will be suppressed during socket connection/disconnection

1 – All result codes will be displayed during socket connection/disconnection

Defaults: 0,1

Example: AT#PERSISTENTSOCKET=1,0

#DLEMODE – Set DLE Mode

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

character.

Syntax: AT#DLEMODE=id,<DEL Mode value>

AT#DLEMODE=id Read or display the current setting (or AT#VTCP=id, AT#VALL). For id, enter a

Profile Setting: 1 or 2 {1,2}

Values: Set the value that the Profile will use:

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 – 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: 1
