one very strange thing i observed is that if i start up the application as auto session application (i.e /./home/user/serial) it will not work
but if i do a command i.e. (xterm -e "/./home/user/serial") the application will work. it seem that as long the application is seen on screen , the serial will work.,. this is very strange

please advice
