I was going through some of my old stuff and found my Courier V Everything modem that I used in the 90's. I even found a printed copy of Crime's email (Flying Penguin remembers this guy), with the recommended settings to play on line.

Oh man, yeah, if you didn't have the right init strings, you were toast. That was part of the secret sauce - kind of like RAM timing is today for performance RAM.

Yeah, I remember one of the first things I did with a new build was to set the init string.
