Hello Shirish,
When was the last time you tried using the RS 232 port? And for what application?
Cheers,

Hello Jayanth,
Thanks for reply, I am checking every day. I am using this for our motion controller application. We connect PC to a Motion controller (Delta Tau make) using RS232. It was working very well earlier, but all of a sudden it stopped one day. However the controller is still working OK with other laptop.

Hello Shirish,
The port may not respond if there is an activity which is continuously consuming the resource.The resource in this case being your serial port. So first of all, try to see what tasks (that utilise the serial port) are active in your computer. Shutdown any unnecessary task and then try again. Your port should start responding.
If the port still does not respond, check the driver files for the serial port. If everything seems fine, I believe it is a hardware issue with your laptop and HP support team should be able to help you in this regard.
Cheers,
Jayanth
