- The only communication "protocol" distributed (in assembler, PASCAL,
- and C) is the ASCII <-> HEXADECIMAL transcoding. Its main interest is
- when you decide to use the Xon/Xoff hand-shaking (integrated in the
- serial ports driver), whereas you have to transmit some binary data...
- Otherwise, there could have confusion - to the driver level - between
- data bytes and Xon/Xoff control bytes !
- ATTENTION: To each hexa. bytes transcoded corresponds 2 ASCII bytes.
- The speed of a link based on this transcoding will therefore be
- divided by 2 ! THEREFORE: Use it WITH DISCERNMENT !...
- For the arguments meaning, please refer to the listing associated
- with the indicated procedures.

- ConvAsc et ConvAscii:
- Converts any hax. byte into 2 binaries associated to 2 ASCII characters
- (whose hexa. codes are greater than 29h).
- ConvHex et ConvHexa:
- Converts 2 ASCII BINARIES codes into THE corresponding hexa. code.
