We need to connect some our device to the LPT port of a QNX v4.25G host.
When we boot the host on windows - everything works fast and reliable.
Does Dev32.par v4.25A support EPP, ECP or just legacy output-only hardware?
I’m looking into
version does not use hardware interrupts at all.
What is the proper way of achieving the maximun throughput on LPT without
burdening the CPU? Should I write the driver of my own?
