M-Bus - MODEM
GmbH, Stettiner Str. 38, D-33106 Paderborn
Normal mode for non M-Bus applications (for example V.42, fax, and
so on).
The factory profile is loaded and saved in the EEPROM profiles 0 and
1 (same affect as AT&F&W0&W1).
Configuration for the calling M-Bus modem on the PC.
This command does not save the selected M-Bus profile in the
EEPROM profiles (if required, enter AT&W0&W1 as well).
Configuration for the selected modem on the M-Bus installation side.
The M-Bus profile is saved in the EEPROM profiles 0 and 1. Important,
the modem does not answer when this command is entered. No echo
is output with all future entries (quiet mode).
Command for outputting the modem type and the software version.
The command can also be used to test the modem with a terminal
program; the modem answers even in "quiet mode" when functioning
correctly.
Commands may be prefixed with the U command in the same
command line, however no command should follow.
For example: AT&FU1<CR> is a correct entry whereas
ATU1&W0&W1 is executed up to "U1" only.
