[jira] [Created] (NET-654) auto add a LF before a command

Zhenliang Su created NET-654:
--------------------------------

             Summary: auto add a LF before a command
                 Key: NET-654
                 URL: https://issues.apache.org/jira/browse/NET-654
             Project: Commons Net
          Issue Type: Bug
          Components: Telnet
    Affects Versions: 3.6
         Environment: all environment 
            Reporter: Zhenliang Su


I use TelnetClient to connect to my H3C router. When I type the first command, it's ok. When I type the second command, TelnetClient automatically add a LF character before my second command, i.e. send an empty command before my second command.

I review the source code of TelnetOutputStream.java, in function write(int ch). When I type the first character of my second command, variable __lastWasCR is true, variable __convertCRtoCRLF is true, and because I set nothing of TelnetOption.BINARY, __client._requestedWont(TelnetOption.BINARY) also returns true。 lead to cause my issue.
