How do I interface the parallelport in Direct RT?
I've got some external hardware that sends TTL signals to the parallellport.
Using the TTL I/O test program at port 889 I get these codes:
Button code
1 8
2 16
3 32
4 64
When running the attached experiment it stops and it seems it doesn't get any input from the parallelport. Have you got any ideas?
Any feedback will be appreciated!
