Thankfully, this belish is all by dead and buried. Whereas the idea might have been good, the implementation was horrible and very expensive (espeically on the Annex end!). And, whereas cooked mode operations may have been cheaper on the host, in cbreak/raw mode (i.e., editting, etc) the overhead was much greater. The protocol was actually RPC based (over UDP), btw. It never performed well and didn't provide "full UNIX tty semantics". It was an endless source of headaches. The only good thing was that the protocol was kept proprietary (it still is, to Encore) and thus never spread anywhere. This means it is enjoying a slow, easy death (too easy by my standards). John
