Hi,

Agree. The only reason not do to so was that I saw the existing code,
especially the else clause in console_baudrate_set().

I just made v2 of the patch. I'm testing it right now. If it's Ok, I'll
submit it.

I did almost exactly this. The difference is that I do not call setbrg()
again if the device is already active. I also removed setbrg() call for
inactive devices from console_baudrate_set() as this would be duplicate
call now.

Regards,
Alex
