ATC MAPPED TO BUTTONS?

[manhattan]

Trying to contact Gywn (Westozy).

Some time ago, you had four red buttons on your yoke which were mapped to ATC. I can't figure out how to use ATC with these buttons?
Even if I use the keyboard keys direct, I cannot hit the relevant numbers shown on the ATC box? Once I enter the frequency, and one of the numbers, I cannot go any further with any other numbers! If you see this message I would be very grateful if you could tell me how it's done?

Does anybody know of a module or software that can be used to operate ATC remotely with proper usable number selections?

Here's hoping.

Maybe you are using the numeric pad? numeric pad doesn't work for me to select ATc options, but regular numbers (the ones bellow the f1-f10 keys) works fine for me. I use the opencockpits CDU which uses a keyboard emulator and pressing the numbers on the CDU also work for me.
