I've ordered Minix for the ST, but haven't recieved it yet, so pardon me
if this is an ignorant question.  At what point does the cursor wrap when
you have line-wrap enabled?  If I were writing the driver, I would have
it wrap when you attempted to write one past the end of the line, *NOT*
when you write into the last column.  This should prevent any problems
with "well behaved" programs which only use 80 columns, even if they use
EXACTLY 80 columns.

On a related topic... Does the exisiting tty driver (for PC or ST) allow
for a variable number of lines on the screen, or better yet a variable
number of characters per line?  I regularly use fonts on the ST which
give me various screen heights between 25 and 50 lines, and don't want to
lose that convenience.  I understand that in certain video modes on the PC
it is also possible to get more than 25 lines.  Which, of course, brings
up the issue of allowing full-screen programs (like editors) to adjust to
the varying screen dimensions... Some food for thought.

I'm looking forward to running Minix on the ST!
