I want to write a vb.net program for serial communication which consists of Tx window Rx window connect and disconnect buttons. When I press connect if the COM port is unplugged then it must give a message in msgbox ? COM port is unplugged please plug it and try again. How to write code for this please any one give a sample code.

You will use the SerialPort class for a start. There are already lots of examples on the web but you should start by reading the MSDN documentation for the class. Do what you can and then post back and show us what you've done and where you're having issues. We can then help you with specific issues rather than building your app from scratch for you.
