@sabi Could you turn it off with ISA modems? Most of what my family had were internal. We only had one external and we preferred the internal.

I suppose they might have had DIP switches or somesuch. I never actually looked at them back then. (They were in my parents' computers, so it wasn't up to me.)

It is useful to hear that it's functioning I guess. I would have liked to turn it down though. The one external did have a volume control.
