Half-Size, Low-Cost Global Embedded Modem

XE5692H Boot Command

The XE5692H allows a default command string to be automatically loaded into the modem on power-up or

modem reset. A series of commands loads the default command string in Hex form into the modem’s

EEPROM. The EEPROM has 256 bytes available for command storage.

The sequence to load the default commands into EEPROM must begin with the Boot command and end

with a double carriage return. All commands are loaded into the EEPROM in Hex form beginning with

address M0000. Up to 8 addresses may be loaded with each command in the sequence.

The following example uses a typical configuration for an embedded application. ATE0 disables command

echo; ATQ1 disabled modem responses, and ATS0=1 sets the modem to automatically answer on the first

ring. This sequence is loaded into the modem EEPROM with the Boot command using the command

sequence below. This places the modem into the desired configuration each time power is applied or the

modem is reset
