Dont Event

Fired when a Telnet DONT OPTION command comes from the Telnet server.


public event OnDontHandler OnDont;

public delegate void OnDontHandler(object sender, TelnetDontEventArgs e);

public class TelnetDontEventArgs : EventArgs {
  public int OptionCode { get; }
Public Event OnDont As OnDontHandler

Public Delegate Sub OnDontHandler(sender As Object, e As TelnetDontEventArgs)

Public Class TelnetDontEventArgs Inherits EventArgs
  Public ReadOnly Property OptionCode As Integer
End Class


The OptionCode parameter identifies the option code. For a list of option codes and their descriptions, please look at the Telnet RFCs. The following are a few examples:

0 (TRANSMIT-BINARY)Enables or disables binary (8 bit) transmission.
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.
