I have seen the same thing on windows when using telnet using the MINA
EchoServer example program. I think it is a windows, not MINA issue.
Yep. Windows telnet client flushes every keystroke, while *NIX telnet
clients flush on a carrage return.

You are using TextLineDecoder in a wrong way. I'd suggest the
following implementation:
1) Use TextLineDecoder as it is; do not extend it.
2) Once you inserted your protocol codec filter, your IoHandler's
messageReceived() will be provided with a line of string.
