Hi again Erik

SDL (Specification & Description Language) is also FSM based, and has
both a graphic and a textual form. Probably the best would be for me
to quote a few references:

"SDL - CCITT Specification and Description Language", Rockstrom and
Saracco, IEEE Transactions on Communications, V30N6, June 1982

"A Meta-Implementation for SNA", Pozefsky and Smith, as above (this is
about IBM's FAPL)

I think the above issue may also have had something on LOTOS.

"Specifications of a Simplified Transport Protocol using different
Formal Description Techniques", Gregor Bochmann, Computer Networks
and ISDN Systems, #18, 1989/90, pp 335-377

The last is a comparison of Lotos, Estelle and SDL.

Hope these will be useful.
