Wait for user action

I am looking for a solution, if it is possible to wait for the data entered by the user in protractor.

I mean test stop for a while and I can enter some value and then these data are used in further tests.

I tried to use javascript prompt, but I did not do much, maybe it is possible to enter data in OS terminal?

Please give me an example if it is possible.
