Yes it is.  However, 115.2Kbaud is the highest speed you can pretty much
rely on the other end being able to do.  Also note that the common Maxxim
RS-232 converter chips and their knockoffs are only rated for 120Kbaud.

I was considering the "standard" baud rates to be 115.2Kbaud and under,
although there is no such official standard.  I guess "nearly universally
supported" would have been a better term than "standard".
