I have a program that uses a piece of external hardware that connects to my comp via a serial cable and COM port but I do not have a COM port on my laptop but instead several USB ports. I bought a USB to Serial cable and connected the serial end to the hardware and the USB end to my laptop but when I run the program it does not recognize that the hardware is attatched despite the fact the use of a USB to serial cable is listed as an option for connecting the hardware by the manufacturer.
The thing is that when I prompt the software at look for available COM ports on my laptop it shows that there is in fact a port listed as "COM3" and that it is working but does not find the hardware on that port. Ive tried connecting the hardware via each of the 4 USB ports I have hoping that one of them is "COM3" but to no avail.
I have another desktop in another room in my house which has a COM port on which the hardware works great. Is there any way I could install a COM port on my laptop and get this thing to work!?!
