Serial port in C#

Oct 16 2008 1:09 PM

Hi, i am using visual studio 2008 and developing a windows forms application in C# using .net 3.5.

I am doing serial communication and on loading the application getting a list of all the comm ports available.  I then scan for the device i am looking for by opening each port in trun looking for the reply.  It all works fine on my PC but when i run the program on a laptop the program thinks there is a COM 3 when there is not such a thing available.  I have tried this on to laptops and the same thing happens and i have tried it on another PC and it works fine.

Where is this COM3 comming from?
