Chapter 1 – AT Commands, S-Registers, and Result Codes

Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H) 17

&W Store Current Configuration

Description: Use this command to store the modem's command options and all S- registers

except S3, S4, and S5. The Z0 command or a power-up reset of the modem restores

these profiles.

Note: This command is not valid during a cellular call.

Syntax: AT&W<value>

Values: 0 Stores current configuration as profile 0.

Default: 0

Result Codes: OK if <value> = 0.

ERROR if <value> ≠ 0.

&Z Store Dialing Location and Number

Description: Use this command to store a dialing string. Controller-based modems can save three

dialing stings.

The format for the command is &Z<storage_location> = <dialing_string>.

The dial string may contain up to 40 characters.

The ATDS=<storage_location> command dials using the stored string.

Syntax: AT&Z<location>=<stored number>

Values: <storage_location> = 0 to 2 for serial; 0 to 1 for parallel.

<dialing_string> = Dialing number.

Default: None

Result Codes: OK if <value> = 0 to 2.

ERROR if <value> ≠ 0 to 2.

Example: AT&Z0=5550123

Note: The command to Store Dialing Location and Number for Callback Security

operates differently from the normal Store Dialing Location and Number.

To store a Callback Security number, type the following:

AT&Zy=[+][-]ATzDvx[,?]

where:

y is the memory location (0-29)

z stands for additional commands

v stands for the choice of T for Tone Dialing or P for Pulse Dialing

x is the phone number

? stands for the optional callback number

Example: AT&Z0=ATM0DT5551212

controlled by the parameter <block size>.
