1.1       deraadt     3:
                      4: The following TELNET options are supported:
                      5:
                      6:        LINEMODE:
                      7:                The LINEMODE option is supported as per RFC1116.  The
                      8:                FORWARDMASK option is not currently supported.
                      9:
                     10:        BINARY: The client has the ability to turn on/off the BINARY
                     11:                option in each direction.  Turning on BINARY from
                     12:                server to client causes the LITOUT bit to get set in
                     13:                the terminal driver on both ends,  turning on BINARY
                     14:                from the client to the server causes the PASS8 bit
                     15:                to get set in the terminal driver on both ends.
                     16:
                     17:        TERMINAL-TYPE:
                     18:                This is supported as per RFC1091.  On the server side,
                     19:                when a terminal type is received, termcap/terminfo
                     20:                is consulted to determine if it is a known terminal
                     21:                type.  It keeps requesting terminal types until it
                     22:                gets one that it recongnizes, or hits the end of the
                     23:                list.  The server side looks up the entry in the
                     24:                termcap/terminfo data base, and generates a list of
                     25:                names which it then passes one at a time to each
                     26:                request for a terminal type, duplicating the last
                     27:                entry in the list before cycling back to the beginning.
                     28:
                     29:        NAWS:   The Negotiate about Window Size, as per RFC 1073.
                     30:
                     31:        TERMINAL-SPEED:
                     32:                Implemented as per RFC 1079
                     33:
                     34:        TOGGLE-FLOW-CONTROL:
                     35:                Implemented as per RFC 1080
                     36:
                     37:        TIMING-MARK:
                     38:                As per RFC 860
                     39:
                     40:        SGA:    As per RFC 858
                     41:
                     42:        ECHO:   As per RFC 857
                     43:

                     45:
1.1       deraadt    46:        STATUS:
                     47:                The server will send its current status upon
                     48:                request.  It does not ask for the clients status.
                     49:                The client will request the servers current status
                     50:                from the "send getstatus" command.
                     51:
                     52:        ENVIRON:
                     53:                This option is currently being defined by the IETF
                     54:                Telnet Working Group, and an RFC has not yet been
                     55:                issued, but should be in the near future...
                     56:
                     57:        X-DISPLAY-LOCATION:
                     58:                This functionality can be done through the ENVIRON
                     59:                option, it is added here for completeness.
