Do you mean that I set the parity or that it is automatically set to 0? The cross assembler character set that came with my documentation only goes up to 122 decimal. When I try to display any printable forms from the extended ascii chart, for example 165 decimal, it does not display the character that corresponds with that number. I can display any character from 122 decimal or lower but above this the displayed characters do not match the ascii values that I choose. Does this have anything to do with the fact that the microconverter is using the 7 bit space parity ascii chart?
