Hi,

Interfacing with parallel port would be a bad idea in that you will have to allocate minimum 8 ports of the micro, which you could use for something else.

And I don't think that terminal packages for parallel port are just available out there ???

Using serial port would only need 2 ports and a ground.

And there are many terminal emulation packages to get and show your serial data. Rather Plug & Play kind.

Regards
