Abstract​

RFC 15 describes how time-sharing hosts should be given access to the ARPANET. Building on the network primitives defined in NWG Note 11, it reviews the basic system calls for opening a primary or an auxiliary connection, transmitting over a connection and closing it, and then proposes a subsystem called Telnet: a shell program around those primitives that lets a teletype at a remote host work as a teletype at the serving host. The document gives the Telnet command set (escape character, connect, logout and file copy), illustrates a complete session from a PDP-10 at Utah to the 940 at SRI, and concludes that such a "level 0" network program, though quickly to be surpassed, would make the early network immediately useful.
