I'm hoping someone out there can enlighten me on the true meaning of
this guru meditation number:  87000004 265F48F1

When I look this one up in alerts.h, it tells me the error was detected
by dos.library and means "Unexpected packet received".  Unfortunately,
this three-word explanation isn't helping me much.

My program is a dos handler for tape drives, written in C.  It also opens
a CON: window and Write()s messages to it.  Three Write()s successfully
execute, then the fourth one prints its message in the window but never
returns to my program; instead I get the "task held" requester, then guru.
To add a bizarre note to this story, it only fails on A2000's and 2500s;
it has never failed on my home A1000+Supra system.

I can't figure out what I'm doing wrong.  Perhaps if I knew more about
what dos thinks is an "unexpected packet" during Write(), and how I could
be creating that situation, I might know where to look.  Is there anything
special I have to do to Write() from a process which is not a CLI (the
handler process was created by Mount)?  What does 265F48F1 mean?

Your knowledgeable replies will be much appreciated!
