I am trying to start a VMS 9.2 VM I have created VirtualBox V6.1 But I get the following problem:

VMS V9.2 needs to boot from a console session, so the VM I have created has a COM1 port defined to connect to a Terminal via TCP port 1023.

I am running Linux Mint 21.3 64 Bit on a Dell Laptop, with VirtualBox V 6.1 as an installed application.

Any help would be appreciated.

The install guide looks like it is written for Windows. With linux, Ports below 1024 are privileged and can not be used by a regular user. Try 1024.

Hi michaelk, thanks for your advice, that worked thank you.
