Is there any way to invoke the Erlang switch command on the CMD on Windows?

Question

When I invoke erl on the CMD I get this output:

Eshell V10.1  (abort with ^G)
1> 

As far as I know, the switch command should kick in when I press Ctrl + G, but instead what I get is a new shell.

Do I have to press a different key combination? Does the switch command exist on erl for Windows?

Because of how the CMD console works in Windows, the standard erl command is not suitable for running interactively. On Windows, you should use werl instead (which is what the installed icon runs) to get an interactive Erlang window. Then, Ctrl-G will enter Job Control Mode as expected.

Note also that the normal Ctrl-C for the Break menu does not work on Windows (since it's used for Copy/Paste) - instead you have to press the actual Break key. See https://en.wikipedia.org/wiki/Break_key#Keyboards_without_Break_key if you can't find Break on your keyboard (Fn-b worked on my laptop).
