The Xboard protocol definition I use is in the Xboard source tar ball,
but I expect Tim has a copy on his website somewhere

icsdrone uses xboard protocol, it doesn't work with early versions of
GNU Chess 5, because GNU Chess had a bug in the "white" and "black"
commands which aren't used by Xboard any longer (IIRC), but it is fixed
in recent version of GNU Chess 5.

Most of the free software engines support Xboard protocol, some support
other protocols, but there is a dearth of free software GUI's and other
interfaces using the alternative protocols.

I'd say Xboard protocol is good for simple interfaces - but for more
complex applications someone needs to either extend it, or use a
different protocol.
