I am writing a Summagraphics digitizer interface for digitizing and area
measurement, and I'm having a small interface problem.
I would like to reset the tablet and re-configure it at run-time, because
Undergraduate engineering students don't like things like TCTL.
If you send a Summagraphics bitpad the HEX 00 character to reset it, it sends
a whole lot of garbage back. Then, it doesn't allow you to talk sense to it.
I've tried time_$wait ing for the garbage to go away, and stream_$get_rec
until status becomes zero to flush the input buffer. I've also tried
closing the stream to the sio line and re-opening it, but this stuff won't
go away. Does anyone know how to simply flush the input buffer an/or
reset a data tablet without throwing it out a window?
Thanks, Scott Ferguson
