Allow me to interject for a moment. Apparently there's a ttylinkd program that "is a simple daemon that allows incoming ttylink calls to be routed through to Linux's normal talkd(8) system". It's TCP port 87 in RFC 1060 "Assigned Numbers", but seems to have been dropped since. Maybe someone can expand on this. Apparently this protocol was known at MIT, because there's a Chaosnet servic called TTYLINK. The client side is implemented by the MINITS Chaosnet router/terminal concentrator/etc.
