This choice makes it possible to change the baud rate. When the meter is updating you will
receive a message when it has been successfully updated. Some meters respond faster than the
M-Bus standard claims so sometimes you will not receive the message although it has been
successfully updated. If that is the case try to test at the new baud rate to see if the meter has
been updated. It is very important to do a test read on the new baud rate no matter what since
some meters change back to the original baud rate if no reading has been done.
