Hi Clemens,

Not exactly.  The above says "Minicom continues to use the original 
value unless you save the setup, then quit and restart minicom."  My 
experience is that changing the baud rate on the fly works, but 
sometimes the port gets into a funky state and minicom "loses control" 
of it.

Unfortunately, it is not reliably reproducible.  :-(  Pure speculation 
is that incoming serial (from powering up the attached development 
board) sometimes confuses the port and minicom doesn't use a big enough 
hammer to reset it.
