Hello - I hope I describe this correctly so please forgive me in advance.... I want to create a 9 button front panel VI that will send a predescribed hex string/number to the computer to act as a command in a third party software package. The key is that it needs to be sent through a USB port so the 3rd party software will react correctly. I believe the correct terminology would be a virtual keypad input device that would be interfaced through a virtual USB port. Does that make sense? The third party software needs me to tell it the Com port to look at for the commands to be coming from. I would like to see it as a device on my Windows device and printers screen as a com port. I would also like to be able to watch that virtual port to see the string that was sent. I did quite a bit of searching here but don't see anything as I am asking for it. I am wondering if my terminology is leading me astray in my searching. I tried to add a port in MAX with no luck. It seems to add it but in the VI, it doesn't show up as an available port and my devises and printers screen doesn't show it either. I tried to add Com2 in the MAX screen shot attached and trying to see it in the Visa resource control in the other picture. Thanks in advance for any help you may be able to give me. Steve

Well sound a bit like a USB4ALL CDC together with a RS232 (or USB2RS232) could create (or should I write HACK 😉 ) a HARDWARE device to look like a RS232 for the LabVIEW device and a HID keyboard for the hole system.
