56K V.92 Data, Fax, and Voice Chipset

9. MANUFACTURING-ONLY COMMANDS

The following commands are provided for manufacturing and testing purposes only. These commands should not be included in end-user literature.

Caution: Serious damage to the controller may occur if these commands are implemented incorrectly.

The test commands AT+FTTn and AT+FRTn allow the modem manufacturer to test the fax transmit and receive modes during manufacturing testing.

The MD566X chipsets include three commands (#VGPO=n, AT#VGP1=n, and AT#VGP2=n) that may be used by modem manufacturers to provide additional or unique features. These commands should not be used by general-purpose software packages.

Description

Country Select: This command is for international use. It sets the country-specific parameters, including S-register settings. The command checks whether an entered country code matches one of the codes stored in EPROM. If so, the entered code is stored in NVRAM. This code is loaded from NVRAM upon power-up or soft reset. The default value is used if no NVRAM is installed or if the NVRAM failed the self- test during reset.

In the case of virgin NVRAM, the country code is not initialized, and the country code ‘0’ will be loaded as a default. This may cause an anomaly such as dial tone detec- tion. The AT*NCn;&W (n=0 to 9) command is required to avoid this anomaly from power-up. The commands AT&F and ATZ do not change the country code after the country is selected by the AT*NCn;&W command. The command ATI6 shows the specific country where that modem operates. The command AT*NCn followed by AT&W has the same effect as the AT*NCn;&W command.
