I need to do a program that uses the parallel port to send and recive information. But i need the time between i active some bit in the port (for example) and then check the status of another bit in the port to be less than 1.5 mS. I'm using Visual Basic.

Do you know if it's posible? It's the parallel port fast enough?

Hi iodem_asakura,

If using the parallel port in its original DOS mode is too slow for your application then you can check into ECP or EPP mode as a way of getting higher speed performance.

Take a look at this website.

Good Luck,

Thanks. But i feel it very messy.
