Ryan; I had studied 3270 and 5250 terminal protocols in the past. These were the streams to update content as the user typed. Both those protocols only sent one changed char at a time. The only change on the terminal was that single char. There was enough information in the push to identify the position, new attributes and the char itself. The whole exchange was less than 10ms. I guess we could say this was a signal which as you mentioned was developed 40 or 50 years ago.
