Actually I'm trying to do it any synch communications. SPI, I2C, and ICSP
will be some of the protocols I'll try and implement.

There is no point in developing anything for the parallel port now.
This is what you need:

Well, I wanted to hook directly up to some devices with minimum external
circuitry. Eventually I might add support for usb and some other devices but
at this point all I have is the parallel port.

I'm essentially just making something that is similar to WinPic. So if I
wanted to program so some pics or play with some controllers that use some
some communications method I could do it quite easily by just typing in the
commands and have the program do the rest(its more work than that but it
would only need to be done once).

Thanks,
Jon
