These constants define what protocol is used when wodTelnetDLX connects to the server.

Raw protocol is the simplest - no special conversion is done by wodTelnetDLX.

When Telnet protocol is used, wodTelnetDLX will handle and negotiate Telnet specific options (such as terminal screen size, speed...).

For SSH1 and SSH2 (and SSHAuto), internally SSH protocol will be implemented.

When SSL/TLS is used, wodTelnetDLX will use secure layer below data communication, so everything that is sent/received by the client is encrypted, but result you get is in plaintext.

SSLTelnet protocol is used for Telnet based daemons that support automatic upgrade to SSL. If SSLTelnet is used, and automatic upgrade is not available, wodTelnetDLX will close the connection.
