Part 4 – AT Commands for the SocketModem iCell, SocketModem IP, and MultiModem iCell

Chapter 14

#AUTOCONNECT – Automatically Connect the PPP Link

Description:

#AUTOCONNECT enables/disables the automatic link connection. The APN or ISP values need

 

to be set correctly.

Values:

0

- AUTOCONNECT disabled

 

1

- AUTOCONNECT enabled

Syntax:

AT#AUTOCONNECT=<value>

 

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

Default:

0

 

#PPPMODE – Set TCP/IP Behavior

Description:

The TCP/IP stack can manage the access layer in different ways. This parameter selects the way

 

the TCP/IP stack must run once the physical is layer successfully established.

Syntax:

AT#PPPMODE=<value>

 

AT#PPPMODE? Read or display the current setting (or AT#VPPP, AT#VALL).

Values:

3 - Standard PPP. The TCP/IP stack behaves as a PPP client for outgoing calls and as a PPP

 

client for incoming calls.

Default:

3

#PPPMYIP – Set IP Address When Using PPP

Description: When the TCP/IP stack behaves as a PPP server (according to the PPPMODE parameter setting), it is in charge of the IP address attribution mechanism.

Once the PPP authentication is successfully achieved, the remote PPP peer asks the TCP/IP stack for an IP address. Then the related PPP layer, called IPCP, suggests an IP address to the peer that has been previously stored in the TCP/IP stack parameters. If the remote accepts this address, the IP link is then established.

This parameter defines the IP address to be attributed to the TCP/IP stack when the PPP Server mode is running.

Syntax: AT#PPPMYIP=<value>

AT#PPPMYIP? Read or display the current setting (or AT#VPPP, AT#VALL).

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

Default: 0.0.0.0

#PPPPEERIP – Set IP Address for Remote PPP

Description: When the TCP/IP stack behaves as a PPP server (according to the PPPMODE parameter setting), it is in charge of the IP address attribution mechanism.

Once the PPP authentication is successfully achieved, the remote PPP peer asks the TCP/IP stack for an IP address. Then the related PPP layer, called IPCP, suggests an IP address to the peer that has been previously stored in the TCP/IP stack parameters. If the remote accepts this address, the IP link is then established.

This parameter defines the IP address to be attributed to the remote PPP peer when the PPP Server mode is running.

Syntax: AT#PPPPEERIP=<value>

AT#PPPPEERIP? Read or display the current setting (or AT#VPPP, AT#VALL).

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

Default: 0.0.0.0
