#ISPPW Set ISP Password

Definition: This parameter sets the password for the ISP account. When communication is initiated and once the

physical (modem) connection has been established with the ISP, the TCP/IP stack software must

provide the ISP with the password associated with the account to be used.

Values: Alpha-numeric ASCII text string up to 64 characters. No default.

Syntax: Set Value: AT#ISPPW=<value>

Get Value: AT#ISPPW? or AT#VPPP, AT#VALL

#ISPUN Set ISP User Name

Definition: This parameter sets the user name of the ISP account. When communication is initiated and the

physical (modem) connection has been established with the ISP, the TCP/IP stack software must

provide the ISP with the user name associated with the account to be used.

Values: Alpha-numeric ASCII text string up to 64 characters. No default.

Syntax: Set Value: AT#ISPUN=<value>

Get Value: AT#ISPUN? or AT#VPPP, AT#VALL

#PPPMODE Set TCP/IP Behavior

Definition: 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.

Values: Integer between 0 and 4 inclusive.

0 Modem. The TCP/IP stack behaves as a standard modem. The data is sent/received to/from a

remote standard modem in a point-to-point connection. No IP/PPP stack is running.

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

for incoming calls. Default 1.

2 Reverse PPP. The TCP/IP stack behaves as a PPP server for outgoing calls and as a PPP client

for incoming calls.

3 PPP client only. The TCP/IP stack always behaves as a PPP client for both outgoing and

incoming calls.

4 PPP server only. The TCP/IP stack always behaves as a PPP server for both outgoing and

incoming calls.

9 Specific. This case is reserved for specific behavior.

Syntax: Set Value: AT#PPPMODE=<value>

Get Value: AT#PPPMODE? or AT#VPPP, AT#VALL

#PPPMYIP Sets IP Address When Using PPP

Definition: 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.

Values: 32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx). Default 0.0.0.0

Syntax: Set Value: AT#PPPMYIP=<value>

Get Value: AT#PPPMYIP? or AT#VPPP, AT#VALL

#PPPPEERIP Sets IP Address for Remote PPP

Definition: 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.

Values: 32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx). Default 0.0.0.0

Syntax: Set Value: AT#PPPPEERIP=<value>

Get Value: AT#PPPPEERIP? or AT#VPPP, AT#VALL
