I believe the reason it didn't work on some modems is that Hayes had a

Yep. stupid patent. Modem companies had to pay or not use it.
If it had the effect of limiting the use or propagation of that escape
sequence, the patent was a good thing.
I always found the delays annoying. How much cumulative time was wasted
while people waited for the computer to get control of the modem?
