Dear All!

I want to interface Parallax GPS with MC9s12DG256 Microcontroller(Dragon 12 Plus Board),  but the problem is that this GPS module send and receive data on a single pin SIO (when using smart mode), while MC9s12 controller have two sci ports but both are available on 2 different pins (data sending on one pin and data receiving on another), how I should interface it, if any one can guide me in writing code (in C language codewarrier) for it, (software uart) like available in picbasic serin and serout. thanks in advanc....
