[net.micro.att] Need help with bitmap operations on the 7300

root@bu-cs.UUCP (Barry Shein) (08/18/85)

This one is taking too much time, does anyone have one working piece
of C code that just puts an array of bits up on the screen. Here's
where I stand now:

	ioctl(w,WIOCRASTOP,&urdata)

causes my machine to panic and re-boot (developers: sources on request!)

	wrastop()

seems to always return -1 with errno == 0

The only way I can see to approach it with tam is through wicon() but
I get a -1 and perror comes up with 'Bad address'.

Rather than trying to send all my attempts maybe someone could just post
a little example (preferably using either the ioctl or wrastop()).

Thanks in advance. This is getting frustrating, especially the panic-reboots,
kinda slows down the debug cycles.
