Thanks for the reply , i will rely on the serial port. i use the old QT since i will later be working with an embedded system which uses embeded linux and QT 3.3.6 , its not been update yet since the process of porting all the QT code to QT 4 or later will be very expensive.


But when i tried installing Qetserialport on ubuntu it failed , i dont know how to proceed.
Any guidance on installing it
