MINA 2 Serial COM port writing
Hello!
In my project I use MINA2 for interaction with device by serial COM port.
I'm interesting in next question: How session wich connectred with single
COM port will behave, in case several threads write in it simulatneously?
In other words, if writing in session is threadsafe, after two callings of
function 'write' two packets in turn, from one and another packet, will go
on wire. If the write() calling isn't threadsafe, whether bytes of packets
will be mixed?

Hi,
sorry for the late reply I was on holidays.
It's thread safe to call session.write. If not please fill a bug report
on JIRA and it will be fixed ASAP.
