Responses can be run-length encoded to save space. A '*' means that
- the next two characters are hex digits giving a repeat count which
+ the next character is an ASCII encoding giving a repeat count which
stands for that many repititions of the character preceding the '*'.
- Note that this means that responses cannot contain '*'. Example:
- "0*03" means the same as "0000". */
+ The encoding is n+29, yielding a printable character where n >=3
+ (which is where rle starts to win). Don't use an n > 126.
+
+ So
+ "0* " means the same as "0000". */
