Is it possible to use either Serial Port at a non-standard Baud Rate - in particular 62.5 kHz? All my modem and telcom apps appear to only offer the standard baud rates, and they also stop at 57.6 kHz, probably because they are provided by the Mac hardware? Of course, if the computer is smart enough to allow this, I may lack the smarts to do it :>( Cheers, PeterC
