[TUHS] Re: pseudo tty history

was there ever a telnet or other remote access program that predated ptys on Unix? Was telnet the driving force for ptys? Did the folks implementing Unix networking bring in ptys before, or as part of, or after networking, i.e. did folks building networking for Unix realize they needed ptys once they started working on telnet, or did they plan for ptys from the get go? I was an observer for some of this stuff, but as a 20-year-old at UDEL I was also quite out of the loop. I also realize there were multiple Unix networking efforts, so this question is somewhat simplistic. I'm assuming rsh came a bit later.
