Hyper V Serial Port Redirector Pro
Windows Server 2012r2 running Hyper-V with a WinXP 32-bit VM. There is a particular application that will only run on WinXP that uses a serial connector to interface with an old diesel governor.
The Serial/IP Virtual COM port redirector creates virtual serial ports for your application to use networked serial devices with the performance and reliability of a 100% kernel driver data path. Download now and try it free for 30 days with our outstanding tech support! Com Port Redirector (CPR) is software that maps ‘virtual COM’ ports on a PC platform. It redirects application data destined to an attached device via the PC’s local serial (COM) port. Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. A device server attached to the network receives.
I have researched on how to pipe COM ports between guest and host but I am either doing it wrong or I am not understanding the capabilities.
Among other resources:
Integration tools are installedEnhanced Mode is enabled for machine and users
On the host in powershell entered:
and it returned with
.pipeCOM3
for my USB to serial adapter. In Hyper-V on the XP guest I edited the COM1 Serial Port setting by selecting Named Pipe and in the pipe name field entered COM3
this caused the Named pipe path: field to display .pipeCOM3
Mar 28, 2018 The Teams MSI will place an installer in Program Files. Whenever a user signs into a new Windows User Profile, the installer will be launched and a copy of Teams application will be installed in that user’s AppData folder. If a user already has the Teams app installed in the appdata folder, the MSI installer will skip the process for that user.

I then connected the serial cable to the port ran Putty on the guest as admin and nothing displays, there is no interaction. I ran Putty as admin on the host and I am able to connect.
I am convinced the issue is somewhere in the 'piping' of the two interfaces but do not know how to troubleshoot further. I am not certain it makes a difference that the host connection is USB to serial and that is causing an issue integrating with the guest. Any help would be appreciated. I will be monitoring this thread closely so should be able to provide additional requested info in a timely manner.
Thank you in advance!

Hyper-v Serial Port Access
Hyper-V provides data from a named pipe into the VM as a COM port. It does not connect that named pipe to the host's COM port, which is what you would need to pass the data through to your VM.
I wrote a Windows program that runs on the host OS and provides a link between the host COM port and the named pipe, allowing you to use the host COM port from your Ubuntu VM.

You need to run this as an admin user.
