* PETSCII/ASCII conversion functions.
* \author Adam Dunkels <adam@dunkels.com>
*
* The Commodore based Contiki targets all have a special character
* encoding called PETSCII which differs from the ASCII encoding that
* normally is used for representing characters.
*
* \note For targets that do not use PETSCII encoding the C compiler
* define WITH_ASCII should be used to avoid the PETSCII converting
* functions.
