Well, not quite that simple, but it _is_ simple.  There are also
some characters that you need to hide in your payload (there's a
simple method to do this) and a byte you need to add to the
beginning of the frame.  There are also several variants of KISS
that mostly do different things with the control byte at the
beginning of the frame and/or add CRC bytes.  Standard KISS protocol
has no CRC or checksum.

Same here, C-code examples under BSD or GPL open-source licensing
that people are welcome to look at.
