Abstract​

RFC 56 describes the logger protocol, a third level protocol that lets a user teletype communicate with a foreign monitor. Each host is assumed to run four programs: a send-logger and a receive-logger, which establish a full duplex link between the user teletype and the foreign machine, and a sender and a receiver, which carry the traffic afterwards. The receive-logger is user zero listening on socket zero; the send-logger connects to it, the receive-logger opens a second link back, and the two loggers then hand over to the sender and receiver. The memo gives a twelve-step outline of this exchange, recommends 128-character USASCII as the network standard code for teletype-to-foreign-monitor communication, discusses the two purposes of the break character (panic button and subsystem exit) and how it should be mapped, and covers command message formats and echoing.
