Well, I'm now to the point where my driver appears to be called at 
tdattach() and tdopen() but it isn't working correctly.  The 
character device associated with /dev/td0 should return a test 
message but it doesn't.

root@hw-ss1# dd if=/dev/td0 of=/tmp/t bs=1 count=20
td:  tdopen() called.
dd: /dev/td0: Operation not permitted
0+0 records in
0+0 records out
0 bytes transferred in 1 secs (0 bytes/sec)


So how do I debug this?  I need the debugger to kick in when I enter 
the tdopen() routine.
