8.1 AT*E2FAX Ericsson M2M Fax Comm. Baud Rate Modification
This command allows the modification of the factory default RS232
comm. setting between standard 9600 baud and 19200 baud. This is
needed as the addition of fax capabilities, within the module, require
communication between fax applications and the module to run at a
higher baud rate than the fax transmission baud rate (In this case the
fastest transmission rate is 9600 baud). Once this command has been
performed, the user must then execute the AT&F command to reset the
module with the new RS232 comm's baud rate.
The AT*E2FAX command allows the user to:
• “Configure” the RS232 Comm. speed default factory profile,
specifying whether the speed should be 9600 baud (standard) or
19200 baud for FAX application comm. This value will then be used
once the AT&F command is next used.
• “Read” what value this default factory profile has been set to.
