Net.arc20: version for qnx 6.3

Why doesn’t exists a version of the Net.arc20 driver for qnx 6.3?. I have a PCI20U arcnet network interface, and I’m needing the driver, do you know where I can get one?

Arcnet is not support under any QNX 6.x.x version.

Do you know why?

No I don’t but if I were to make a guess I would say because it’s very very old technology and when QSSL created QNX6 they decided to not provide support for it, plain and simple.
