Hello,

As I said my need is really to interface with dos programs, in a simple and basic way. I am not looking for a protocol, just a GPIO.
For me the real world is something inside the computer or next to it.

In other words i am looking for a improved parallel port, with one instruction I could do something like "outportl(0E300, toto)" and this would directly set a 32 bit gpio port. (the same with "inport").
Max frequency is 1 Mhz, but generally it is much less.
I don't even need interrupts on PCI port.
