Description:

Implements the telnet client protocol.
Provides limited writeStream protocol, allowing
data to be sent to the partner via #nextPut: like protocol.
Input arriving from the telnet partner is forwarded to my
outputStream.
A concrete application is found in TelNetTool, which connects me
to a TerminalView.




[instance variables:]
    connection      <Socket>        the telnet connection

    outputStream    <Stream>        data arriving from the
                                    telnet connection is forwarded
                                    to that stream.

    state           <Symbol>        the telnet protocol state.

    sb, sbData                      internal buffer for
                                    SB..SE data
