Part 1 – AT Commands for All Universal IP Devices Chapter 1 – General AT Commands for All Universal IP Devices

Z – Default Configuration

Description: This command restores the configuration profile from NVM. Settings are recalled on power up.

Syntax: ATZ

Response: OK (Command valid)

&C – RLSD (DCD) Option Turn On or Off

Description:

The modem controls the RLSD output in accordance with the parameter supplied. This

 

command sets the DCD On or Off.

Syntax:

AT&C[<value>]

 

AT&C? Read or show the current value.

Values:

0

– Sets DCD to remain On at all times.

 

1

– Sets DCD to follow the physical connection.

 

2

– DCD follows the state of the TCP/UDP connection.

Default:

1

 

Response:

OK

 

Otherwise ERROR

&D – DTR Option

Description:

The modem reads the DTR to determine if the Data Terminal is Ready. This command allows the

 

modem to act on the DTR.

Syntax:

AT&D[<value>]

 

AT&D? Read or show the current value.

Values:

0

– DTR is ignored (AT&D with no parameter).

 

1

– An Active to Inactive transition disconnects an active TCP/UDP connection

 

2

– (For Non-MT100SEM) An active to inactive transition disconnects the physical connection

Default:

0

 

Response:

OK

 

Otherwise ERROR

&F – Reset Factory Defaults

Description: For MT100SEM: This command replaces all settings with the factory defaults but does not store them to memory. Use &W to store them to the memory.

For NON-MT100SEM:This command replaces the factory defaults of &D, &S, &C, E, and V only.

Note: The module must be RESET to put this command into effect.

Syntax: AT&F

Values: None/No parameters

&S – DSR ON or OFF

Description:

This command sets the DSR to ON of OFF.

Syntax:

AT&S[<value>]

 

AT&S? Read or show the current value.

Values:

0

– Sets DSR to remain ON at all times

 

1

– Sets DSR to follow DCD

 

2

– DSR follows the state of the TCP/UDP connection

Default:

1

 

Response:

OK

 

Otherwise ERROR
