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.
	Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP).
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

1All 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).

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

Values: Set the value that the Profile will use:

0When 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.

1When 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: 1
