Interesting. I used to buy Zoom modems in the 80s-90s (https://en.wikipedia.org/wiki/Zoom_Telephonics), but apparently they have nothing to do with either of the other two Zoom companies mentioned here. I had occasionally wondered but never looked into it until now.

Back in the day, wasn't it either Zoom or Hayes?
