I apologize. I didn't think before I typed my original message.

I'm wanting to configure P1.0-7 and 4 pins on P3 so I can interface to the PC LPT port in order to communicate to a 8052 derivative chip such as Atmel 87C52 or similar at 2M+/sec instead of the slower serial port interface that all the documentation I have access to describes. If someone could point me in the direction of some real documentation on how to interface to the 8052 I would greatly appreciate it.

The interface that I already have software developed for is LPT to 82C55A PIA, and I don't want to have to reinvent the wheel (code reuse, and other excuses for laziness apply)

I'm probably going to end up using a TI TUSB3210 controller in the design (USB interface, etc).

Hope this de-confuses my prior message.
Thanks again,
Erik Larsen
