> Project: Commons Net
> Issue Type: Bug
> Components: Telnet
> Affects Versions: 3.6
> Environment: all environment
> Reporter: Zhenliang Su
> Priority: Minor
> Attachments: Main.java, sendb.png, sendcr.png, telnetClient.pcap
>

> 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.
