Thank you. I did not quite understand how the EchoServer worked. I made
some incorrect assumptions and sent off an email to the list before
investigating how the program worked.

Hi Mark,
The echo server example writes back what it received immediately. I
tested
it with MINA 1.1 and telnet-bsd, and it seems to work perfectly.
The read() call in your code will block until the connection is closed or
data is received. If you want to close a connection, please let the
server
close the connection, or let the client throw a timeout exception by
setting
SO_TIMEOUT.
HTH,
Trustin
