Update: 20X2 raw port successful 01-14-2012

I am getting attached to the AXE133Y OLED module having moved from using the module as designed for serial input, to hacking around with the internal display code, to adding line buffers and advanced spooling routines, and now to changing out the 18M2 for a 20X2.
I made only a few lines of changes to use the 20X2 on a homemade carrier board constructed from an old predrilled PC project board... (of course, you must change the PICAXE model declaration, too!)
Notes:
- On the 20X2, pin C.6 is an Input Only pin
- Compiler cannot handle SYMBOL definitions for 20X2 ADC
All the "old" code is as available here for the 18M2:
http://www.picaxeforum.co.uk/entry.php?39-IR-set-18M2-clock-implemented-into-AXE133Y-OLED-display
Disclaimer: The code initializes, displays the 'not set' message and provides the 2 display lines to inform the user that they need to set the clock and to use the TV remote control. I have not moved the clock circuit or the IR circuit over to the new 20X2 board, so some future modifications may be in order.
Why: Well, because I can and because I want to play around with scratch memory and possibly background receive. Plus, I wanted some more breathing room for code.
A full set of picture are here: http://flic.kr/s/aHsjxoyd98
As I move more hardware onto the new daughter board, I will upgrade the code and post resolution to issues.
