Hi all,
I'm developing serial port program in VB.NET. [Just open,read,write and close.]
I referred the following article - "How to access serial and parallel ports by using Visual Basic .NET." I used the given code . Getting unhandled exception .It occurs while executing Getcommstate API call.
As well as downloaded a sample program (RS232-Visual Basic .NET Code Sample: Using the COM Port in VB.NET) from MSDN website and tried.

Problem is, couldn't get connected continuously. Most of the time it's giving an error "Unable to communicate with modem".
How to solve this problem? if u have working example, kindly share it. or give me a link.
Thanks!
