Now I know I am being dumb here...

How can I find out that $x is a single character of ord 00-ff vs a 
number:

	That is - "1" does not eq chr(1);

The reason is that I get a log of people doing this

	$pp->set_byte(0, 1);

And of course I set the value on the parallel port to ord("1").
What I want to do is, if someone has given me a number - rather than a 
string, that I convert it to a character.
	chr(1);

What is the safest way to do this ?

Scott
