Ah - Ok, so If I sent binary 00000011 I would be ok, but If I sent 00110011 (51 - the ASCII code for 3 - in binary) then I would not be ok.

However, If I received a character and wanted to check what it was, would I have to check its value or could I check it directly. For instance, the ASCII code for '+' is 43. If I wanted to check if a received character was '+' or not, could I use:

IF variable = '+', or would I have to have IF variable =43 ...


Thanks, and sorry for all the posts,
