6bits are encoded per character. The argument, aString must be a multiple |
18633 | 197 |
of 4 in size (since 24 is the lcm of 6 and 8). |
198 |
Every 6 bit packet is encoded as a character in 32..95. |
|
199 |
Characters below 32 are ignored (so line breaks can be inserted at any place). |

An addition final byte defines how many bytes of the last triple are valid. |
18633 | 201 |
This is somewhat like the radix-encoding used in good old PDP11 times ;-) |

ST-80 uses this encoding for Images ... |
16798 | 203 |
This is a base64 encoding, very similar (but not equal) to the algorithm used in RFC1421. |

PS: It took a while to figure that one out ... |
