Good suggestion. Consider it added to the list. -Jeff Woolsey, Windows Server
What type of device are you trying to use? Have you used the RDP client to share a USB device into the VM? That works for many devices... -Jeff Woolsey, MS

Thanks for the comment folks. Acknowledged. -JW
COM ports have been around since the dawn of the PC (PC-AT anyone?) and were never designed to be virtualized. If we mapped a physical serial port to a VM, access to the device would fail when the virtual machine Live Migrated or failed over in the case of unplanned downtime. The solution is to use a Serial over IP solution. There are a number of options on the market which provide transparent access to serial devices over TCP/IP and can cost as little as $45 per device.
With these solutions you can achieve both COM port access within a VM without sacrificing VM Mobility.
This has been added to Windows Server 2016 and Hyper-V Server 2016. Enjoy, -Jeff Woolsey
