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

Chapter 14

#ATCMD – Customize Dial-Up Commands

Description: This command allows the user to customize AT commands on dial up.

Syntax: AT#ATCMD=id,"Valid AT command"

AT#ATCMD=id or AT#VALL

id:Enter a Profile Setting: 0, 1, 2, 3 {0,1,2,3}

Values: Set the valid AT command (Do not include AT or issue &F, as the command will error)

Defaults: For Analog Devices: 0, "-STE=1" 1, "+MS=V34" 2, ".."

3, ".."

For All Other Devices: 0, ".." 1, ".." 2, ".." 3, ".."

#REDIALCOUNT – Set Connection Attempts Allowed

Description: This parameter indicates how many unsuccessful connection attempts the TCP/IP stack software will make before terminating the connection attempt activity.

Syntax: AT#REDIALCOUNT=<value>

AT#REDIALCOUNT? Read or display the current setting (or AT#VPHY, AT#VALL).

Values: Integer between 0 and 14, inclusive.

If the value is set to 0, the TCP/IP stack software will not make any call retry.

Default: 5

#REDIALDELAY – Set Call Retry Delay

Description: This parameter controls the delay (in seconds), if any, that will exist between each call retry.

Syntax: AT#REDIALDELAY=<value>

AT#REDIALDELAY? Read or display the current setting (or AT#VPHY, AT#VALL).

Values: Integers 0 and 5–14 inclusive.

If this parameter is configured to zero, the TCP/IP stack software will attempt another connection immediately after terminating the previous unsuccessful attempt.

Default: 5

#PHYTIMEOUT – Set Inactivity Time

Description: This parameter is used by the TCP/IP stack software in order to terminate connections to the telephone line when a long period elapses without activity. “Without activity” is defined as a period when no data is transferred between the Internet and the TCP/IP stack software or between the TCP/IP stack software and the attached equipment. This timer prevents the telephone line from being connected indefinitely for any reason.

Note: When the inactivity timer expires, the modem ends the communication.

Syntax: AT#PHYTIMEOUT=<value>

AT#PHYTIMEOUT? Read or display the current setting (or AT#VPHY, AT#VALL).

Values: Integer between 1 and 255 inclusive. This timer is set in minutes.

Default: 15

Return Codes: TIMEOUT: The inactivity timer is reached; the modem ends the communication.
