How to Create Virtual Comm Ports in macOS

Hi,

In older versions of the OS we were able to create virtual comm ports by adding BT 232 devices. We would go to to Bluetooth, Advanced and add a virtual serial port.

Is there a new way to accomplish this? I need to setup a pair of virtual serial ports on the macOS.

All of the documentation on this is very out of date.

Thank you for any support

Cheers,
