Hello Piclisters,
I'm interfacing LCD modules to the 16F84 in 4 bit
mode. 
Everything is ok with 16x2 'no-name' module
equipped 
with ks0066 but on the LM16255 (16x2) which has a
HD44780A00 
and 8302B07-2 (or is it M5259 ?) the busy flag
doesn't 
get 0 after writing the 8th char (in normal h'28'
mode). 
If I just  ignore the busy flag I can write the
9th one
which works as supposed.
Is this normal? 

I'm using the initialization described in Sharps
DISPLAY UNIT 
USERâS MANUAL Dot-Matrix LCD Units (with built-in
controllers)
p14 (3* 3, 2, 28, 8,  1, 6, C)
