OK... now we're on a different subject.

What type of LCD are you using? If it is a serial LCD, you don't need the following line.
Code:
DEFINE LCD_LINES 2
If it is not a serial display and it has an HD44780 controller, you need some other LCD defines in there. But since I don't know, I'm going to assume it's a serial display. Next the serial part. Try...
Code:
serout PORTB.1,T9600,["A"]
Next, the blocks on the LCD... try adjusting the contrast.

edit: Looks like Skimask was quicker on the draw. Ignore redundant information from me.
