The controller returns with the RPL and CPL flags set.
On error the RPL, CPL and ERR flags are set and an error code is
passed in bits 15:00 of the reply word.
Notes:
The controller accepts all well known baud rates. Furthermore any baud
rate that can be programmed with a resulting error of less than 1% can
be chosen.
The baud rate chosen by this command is retained across openings and
closings.
