| 6 | * The Commodore based Contiki targets all have a special character |
| 7 | * encoding called PETSCII which differs from the ASCII encoding that |
| 8 | * normally is used for representing characters. |
| 9 | * |
| 10 | * \note For targets that do not use PETSCII encoding the C compiler |
| 11 | * define WITH_ASCII should be used to avoid the PETSCII converting |
| 12 | * functions. |
