I'm curious if this also applies to the 4801, as I have a daq system 
that I can't get my soekris board to talk to over serial using the same 
software as I've used under linux and Mac OS X.  It doesn't use any 
flow control, if that makes any difference.  Might I have a serial chip 
that's shutting down when I don't want it to?
