Dear,

Two months ago I faced with commoncpp framework and decided to include 
it in my project. I was really enjoy working with commoncpp. Threads, 
unix sockets and serial port were used. It works fine. But I have one 
issue connecting with ost::SerialService class. Below there is a 
description of it.

I created AppSerialPort class derived from ost::SerialPort. The new 
class is self-deleting class like ChatterSession from tcpservice demo. 
It deletes itself when serial port has disconnected. But such 
implementation leads to segmentation fault. Because ost::SerialService 
attempts to get access to deleted object. To solve the issue I've made a 
few changes in the ost::SerialService class which are similar to 
ost::SocketService class.

I'm sending you the patch. Please try it and see the difference. For 
more information I have attached short demo. You can launch it before 
and after patch. Hope it helps to improve the code.

Andrey Mandychev.
