+Summary: UDP Packet contains false data
+Description of Problem:
+Sending UDP datagrams containing #FF (as my app should do) does not work
+with Linux (debian) and Windows (XP). My code is compiled with Microsoft
+vbc unter windows and then run with mono. The false behavior does not occur
+when running with .NET RTM but with mono.
+Steps to reproduce the problem:
+Here's my code (VB):
+Dim Sv As New clsRCon("", 12005)
+Sv.udpSend("rcon PWD say ""Text to appear in in-game console...""")
+Public Class clsRCon
+    Public Sck As UdpClient
+    Public rep As Net.EndPoint
+    Public Sub New(ByVal HostAddr As String, ByVal Port As Integer)
+        rep = New IPEndPoint(IPAddress.Parse(HostAddr), Port)
+        Sck = New UdpClient(HostAddr, Port)
+    End Sub
+    Public Sub udpSend(ByVal CommandText As String)
+        Dim Header As String = Chr(255) & Chr(255) & Chr(255) & ChrW(255) &
+        Dim TMP As String ' = New String(Chr(255), 4) & Chr(2) &
+CommandText & Chr(0)
+        TMP = Header & CommandText & Chr(0)
+        Dim Buf() As Byte = System.Text.Encoding.Default.GetBytes(TMP)
+        Try
+            Sck.Send(Buf, Buf.Length)
+        Catch e As Exception
+            Console.WriteLine(e.ToString())
+        End Try
+    End Sub
+End Class
+Actual Results:
+The data-part in the datagram starts with: 
+As you can see from the sample code the correct data would be:
+How often does this happen? 
+Always (spoken for me)
+Additional Information:
+I did not test this code with mcs-compiled binaries yet since I would have
+to rewrite the code (will try tomorrow)... But anyway: IL should be IL, right?
