        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
