mina serial communication problem.

[Jun Dai <wi...@gmail.com>]

Dears,
I'm newbie to mina serail communication.
I wrote two java application hosted in two machines to communicate by serail
port using mina.
One application sent "hello world!" and another application's messagereceive
method worked very strange.
Some times, it can receive "hello world" but some times, the messagereceive
fired only "hello w" and "orld!" will fire by a following messagereceive
fired.
I want to get the "hello world" in one messagereceive so that I can easy
control it.
Can any friend help me?
Thank you!

There is _no_ guarantee that the message will be received in one single 
piece. You may perfectly receive each char in one single message, too. 
This is up to the server to concatenate the received messages to get the 
whole message, so you have to manage some kind of terminator to know 
that your message has been fully received.
