In <Low ECP speed> message I saw that all outb take 2uS (500 KB/s)
and all outsb take 128uS to read 16 bytes using a onboard port.
I haven't solved the problem but because 500 KB/s is too slow I will
go to use a PCI parallel port card. I need a throughtput of 1 MB/s.
I have any questions:
- I read that there isn't DMA support on PCI. It has bus master support
and there aren't PCI parallel port card bus master capable.
Is it true?. Do I must use PIO access code?
- In many EPP parports there are 32 bit transfers support.
Can I use 32 bit transfers in ECP parports?
