Not yet.  My SCC init routine is purposefully written to talk to the
SCC registers directly - bypassing the CtrlA-1-5-B business.  (I groked
the Darwin source code for insights into SCC programming...)

I can set up the timing constants up to 57,600, but I'm not sure the
firmware can keep up at anything past 19,200.  I have example code from
a BBS, and of course we have Apple's Technical Note #18 that goes into
detail about interrupt routines that play nice with AppleTalk, etc.  I
think the grail of 57,600 BPS lies down one of those paths.  I'll need
another vacation's worth of geek-time to get that sorted out.
