A brief HOW-TO for various apps:
===============================================================================
The examples below were tested using a Nan Ya 128x64 KS0108 based garaphic LCD
===============================================================================

GLUTIL Program 
-------------------
The hex file required for this program to work is:
GLUTIL.HEX  - Requires that EEPMINI.HEX be run at least once to load the characters in the eeprom
GLUTI2.HEX  - same as above but this one loads the mini characters each time it runs
The Windows application for this is GLUTIL.EXE Ver 1.2 and higher

EETERM demo
----------
This requires that BOTH eepmini.hex and eeaplha.hex be run at least once
the baud rate must be set at 9600 8,N,1
EEALPHA.HEX loads standard character set in to the external eeprom
EEPMINI.HEX  loads the mini character set in the internal eeprom
EETERM.HEX is a terminal demo which uses the mini and standard characters

This app is mainly a demo to illustrate the use of standard as well as mini characters and also to show what can be done via a terminal, if one was using PICBasicPro one could add other functions to it like setting/unsetting a pin etc.

GLIPIC
---------
GLIPICW.HEX requires to be loaded in the PIC
Note: when this program first runs the LCD is blank

Use Windows GLIPIC2.EXE
