Does anyone know the details of the X11 protocol requests and replies
implemented by the "HPExtension" server extension?  It seems to be
present in the server supplied with HP-UX 6.5.  How stable is this
protocol, and is it the same in 7.0?

The operation I need most is one that tells what display mode the server
is in (as in XHPGetServerMode).  By monitoring a connection with XScope,
I've deduced that a request with the minor opcode 26 seems to return at
least that information.  I'd feel more comfortable knowing exactly what
my request is doing, though!

I need the protocol bits because I'm working in Franz Allegro Common
Lisp, with CLX.  For portability to other Lisp platforms (which would
still access the HP server as clients), I'd like to keep all the code in
CLX.  It's quite simple to implement new "Xlib" calls in CLX, once you
know what bits to send and receive.

	thanks,
