 The Synchronet Terminal Server will negotiate Telnet options with the client (enforcing echo and non-line-at-a-time modes), perform ''IAC'' (character 255) escaping, and CR/LF->CR and CR/NUL->CR translation (when not in //binary mode//). The Synchronet Terminal Server will negotiate Telnet options with the client (enforcing echo and non-line-at-a-time modes), perform ''IAC'' (character 255) escaping, and CR/LF->CR and CR/NUL->CR translation (when not in //binary mode//).

 +==== Options ====
 +
 +Telnet options are negotiated between the client and server, normally without any indication to the user.
 +
 +Telnet options can be re-negotiated at any time during a Telnet session, but most options are only negotiated during the initial connection.
 +
 +^ Options       ^ Request ^ Description ^
 +| ECHO          | WILL    | Server will provide the echo of input keys, so request the the terminal does not echo (RFC-[[rfc>857]])|
 +| SUP_GA        | WILL    | Server does not send or expect to receive any Telnet Go-Ahead (GA) commands (RFC-[[rfc>858]]) |
 +| TERM_TYPE     | DO      | Server would like the client to provide the terminal-type, if available (RFC-[[rfc>930]]) |
 +| TERM_SPEED    | DO      | Server would like the client to provide the terminal-speed, if available (RFC-[[rfc>1079]]) |
 +| SEND_LOCATION | DO      | Server would like the client to provide the user's location, if available (RFC-[[rfc>779]]) |
 +| NEGOTIATE_WINDOW_SIZE | DO | Server would like the client to provide the terminal dimensions (cols x rows), if available (RFC-[[rfc>1073]]) |
 +| NEW_ENVIRON   | DO      | Server would like the client to provide environment variables (RFC-[[rfc>1572]]) - unused |
 +
 +The BINARY_TX option (disabling special treatment of CR/LF and CR/NUL) is dynamically negotiated as needed, for file transfers.
 +
 +=== Debugging ===

 +The Terminal server logs all Telnet option negotiations using a //Debugging// log-level:
