Just a footnote to the comment on sunos 4.0 limiting i/o speeds.  I
have just finished the official Sunos 4.0 course and this question was
asked.  The answer given at the time was slightly different that that
in the orginal articleand explained this apparent deficiency as being
two part. One, the hardware for the cpu ports has a single character
buffer which at high speeds generates too many interrupts for the
operating system to handle.  Two the new drivers allow higher speeds
but the documentation is a little foggy on the limitations.

So don't let this minor set back deter anyone from using his Trailblazers
at 9600.  This is a 1000 times improvement over 2400 especially for news.
