Now, on my 386DX25, with 16450 UART, a "saturated" 38.4 connection dogs my
machine, I'm talking about virtual consoles not "snapping" instantaneously
when you hit Alt-Fx! I can't imagine what locking the port at 57.6 would
do ;). (There's no hope for replacing the UARTs, the multifunction I/O
card I got stuck with implements them "interally", there aren't any to rip
out and replace. :( )

As I learned before from someone else:
$ stty crtscts </dev/cuaN
does wonders, it cleaned up all the CRC errors.
