Serial port problems on the sparc I

["Mark_Weiser.PARC" at xerox.com]

I have seen this happen when when SLIP was running and I was using the raw
console.  Don't do that!  Use a window system, or use one of the new
console emulators recently mentioned in sun-spots.  The serial lines and
the raw console both use the forth interpreter in the sparcstation rom,
and it can't keep up with both.
