Program Code for 4x20 character LCD Module

Dear all,

I'm using a 4x20 character LCD module and interface it with a 68hc11 MCU. I need to display the data inside the MCU by transferring it through parallel port c and b. I had tried writting the intialization program and the displaying program but the LCD does not seem to have any respond and i'm not sure what is the problem. So, anyone have experince dealing with LCD before and have such a program, please share it with me.
