At 57600, we're talking about 1400us to respond before characters are
lost. Whats blocking for that long? TTY is > then NET and BIO, right?
I know so little about low level x86 hardware its not even funny; but
recompiling the com driver with interrupt at 4 chars rather than 8,
would give us some ideas about how long things are being locked down in
the i386 port.
