How can I develop a driver communicating with EPP port?

[?]

How can I develop a driver communicating with EPP port, while I don't want to use In port and Out port.because they are slow.

Hi Mr. ?

I don't have a final solution for you but would like to know, how fast do you want to be. Maybe you can solve your timing problem with given possibilities.
I realised enormous differences in performance at LPT-port; if your PC is fast enough, use of operation system with best performance, the vi-execution settings are at "highest priority" and in addition a PCI-board with additional Printerport is much faster then the LPT from motherboard. I have tested different combinations with my own "benchmark program". For a project I had to read 128 bit via SPI-Interface by use of LPT. Find attached the picture of frontpanel with results. This gives already an impression how different execution time on different Pc's might be...........
If you want to tes
t this vi on your machine - let me know.

Get the book "Parallel Port Complete" by Jan Axelson. She discusses
all the ins and outs of programming EPP, ECP, SPP, etc.
