Can I enable EMS on a Nano VM and connect to this using Putty via a named serial pipe

Question

Hi Folks

I am running Hyper-V on a lab Windows 10 box.

Can I enable EMS on a Nano VM and connect to this via Putty using a named serial pipe?

If so please can you help as I cannot get this to work:

Hyper-V Manger

Configure Com1 on the Nano VM with a name
\.\pipe\web01

On the Nano VM (Via Powershell)

bcdedit /ems on
bcdedit /emssettings EMSPORT:1 EMSBAUDRATE:115200

Putty (Run from W10 Hyper-V Host)

Set to Serial
Serial Line: \.\pipe\web01
Baud: 115200

Error:
Unable to open connection to \.\pipe\web01 Unable to open serial port.

It could be related to permissions. You can try running putty.exe as administrator.
