A single character Telnet option code to be sent to the server with the Telnet DONT command.
Syntax
telnet.setDontOption( dontOption, [callback])
Default Value

Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getDontOption([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setDontOption([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message

| 1 (ECHO) | Telnet ECHO option. Specifies whether bytes sent should be echoed or not. |
| 3 (SUPPRESS-GO-AHEAD) | Used to enable or disable transmission of the Telnet GO_AHEAD command. |
| 24 (TERMINAL-TYPE) | Allows or disallows terminal type negotiation. |
| 31 (NAWS) | Allows or disallows window size negotiation. |
