ESXi – Connecting to a named pipe

Within this article we will be creating a named serial pipe on 2 machines to allow us to connect to a virtual machines serial port.
In this example we will use hyperterminal on a virtual XP machine to connect to the serial port of another virtual machine (in this case SUSE Linux)

Adding a serial port (named pipe) to your virtual machine

  1. Make sure the machine is switched off
  2. Right click on the virtual machine and select edit settings
  3. Under the Hardware tab select add.
  4. Select Serial Port then Next
  5. Select Named Pipe and enter a Pipe name (we will change the near end and far end in a mo)
  6. Click next and finish

Required Settings

Once we have a serial port on the 2 virtual machines (client and server) we need to set them accordingly.
Within the hardware settings of the virtual machines serial port you will need the following settings as follows,

  • XP      – Near End  Client   Far End  Virtual machine
  • SUSE  – Near End  Server  Far End  Virtual machine

Below you can see the settings for SUSE (the named pipe/serial connection on the SUSE box)

Below you can see the settings for XP (the name pipe/serial connection we are connecting to),

XP - Connecting to a named pipe



In order to connect go into windows open hyperterminal and connect to COM1, you will now be connected to the named serial pipe.


If there is no connection you will need to make sure that you have not connected your Hyperterminal connection after the SUSE box has powered up. I normally open hyper-terminal in XP and then power the other device up.
