Detailed Description

An implementation of the standard Telnet Suppress Go-Ahead option.

Overview

The Telnet specification suggests strongly that communications between client and server follow a "half-duplex" protocol, in which the client and server indicate that their "turn" is over by indicating that the other end of the connection should "go ahead". This option was designed to enable the communications to engage in a "full-duplex" protocol, where each party in the connection can transmit data at any time.

While all modern servers and clients now begin with the assumption of a full-duplex protocol, there is one extra feature in Suppress Go-Ahead that remains useful: if a server has both this and the Echo option active, then it is "commonly understood" that this should enable character-at-a-time mode instead of the normal line-at-a-time mode.
