Indeed. We were commonly using telnet in those days. Slightly amusing side story. Some of the guys had gotten those Motorola Timeport pagers with the screen and qwerty keyboard. One of them had rigged up some scripts so that he could send a text message with a Unix command, and his workstation would text him back the output of the command. Hilariously insecure, but a pretty cool demo at the time.
