What ASCII format do we support?

 The serial reader sends the card and delimiter data in ASCII Hex format. The reader will send the card data using ASCII characters 0 – 9 when the reader is in decimal mode and
ASCII characters 0 – 9 and A – F when the reader is in hexadecimal mode. The delimiters
supported are ASCII characters 00 – 7F when entered using the virtual keyboard
in the rf IDEAS configuration utility.
