Anil,

As the error indicates you might be reading data when there is no data to read or the time specified in the timeout property is reached before any data was read.

Having a Timeout of 0.1 sounds too small. Is there a reason why you have that value to 0.2 instead of the default value of 10?

You should also check the BytesAvailable property of the object. That indicates the bytes you have available to read.

Hope this helps.
