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

Universal IP AT Commands Reference Guide 85

#ISPUN – Set ISP User Name

Description: 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.

Syntax: AT#ISPUN="<value>"

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

Values: Alpha-numeric ASCII text string up to 64 characters.

Default: No default.

Incoming Call Management Commands

#ACCEPT – Answer Incoming Call

Description: This command directs the TCP/IP stack to answer an incoming call. When the TCP/IP stack

receives an incoming call, it sends over the serial port the “RING” messages. Depending on the

value of the ANSWERMODE parameter, the TCP/IP stack may answer automatically or not.

If ANSWERMODE is set to 0, it is the host that is responsible for answering the incoming call.

Once the physical layer is up, the TCP/IP stack runs.

The AT#CONNECTIONSTOP command ends the connection by going on hook.
