My program reads text in from a serial port. This is the output from
a piece of test equipment. I need to convert each character of the
text to a binary format so that I can interpret it.
I do this in an ugly fashion by converting to ASCII, then converting
to Hex and then to binary.
So, if I receive the letter 'A' it becomes ASCII = 65, hex = 41,
Binary = 01000001.
The problem is that this equipment sends characters which range from
0-255 not just 0-127, so I guess it uses an undefined or unofficial
ASCII table.
I have other serial drivers which can return these values correctly,
so I know it is possible. But, those drivers won't work for this
application.
If there is a better way to get the binary of the characters I'd love
to know it.
Meanwhile, what I after is a way to figure out the value of the
character (whether it's ASCII or not) .

This works fine until I hit a character with an ASCII value greater
than 127. After that I get unpredictable results.
ASCII is a 7 bit code:

You'll have to explain more of what you're trying to do....
