I am running into the same problem with QNX 6. I am setting up computers for a embedded systems class and the robot arms connected to the parallel port goes crazy. It doesn’t happen with the QNX4 machines.
Do I need devc-par to be running in order to access the parallel port? or if I don’t how do I remove it from the /etc/system/enum/devices/char file?
first try to slay devc-par as starless suggested. if you still have problems, as in the other thread, you could try to remove parallel part enumeration by remove the whole block
The sight of a robot arm suddening going insane and starting to fold into itself is not a pretty sight. Removing the whole block does solve the problem. I will check to see if I can access the parallel port just by I/O address without the presence of devc-par
Does anybody know what devc-par preiodically send/do to the parallel port?
