After a quick look though st.c and friends (README.st is worthwhile
reading), here's what I got. There are 4 'modes'.  The mode are
configured my the system admin for the use of the users.  Each mode is
identified by bits 5,6 of the minor number.  So 0 == 0, 96 == 3, 64 == 2,
32 == 1.  What I'd try is to compile the program/script I posted earlier
and use it to display the options for each mode (/dev/st0?).  If you do
try this, could you post the result?  They could be interesting.
