On a higher level relative to protocols, cinema relies was too much (IMHO) on issuing open-ended commands. Doremi makes a network connection, fires out a command string, and closes the connection. Actually (relating to fader command discussions) we are not sure if the Doremi properly closes connections. That might potentially cause commands to be lost after a period of time (when handles are exhausted).
There is no ability for JNIOR or anything else to send back an error code or even acknowledge the command. So you might potentially not know of the problem until a patron walks out and asks if the show has sound? Or, if the house lights will go off eventually? Even though it is TCP that is not much better than UDP in this case. You know the joke? I'll tell it to you but you might not get it.
This is a lack of protocol.
And I kind of miss the KSR33 Teletype. Can you even buy paper tape anymore? Let alone roles of paper? I also really kick myself for contributing my modified Selectric typewriter to the dumpster. It had a parallel interface so I could use it as a printer (c1978).
