Yeah, I seem to recall several BBS programs that ping the user after so much time goes by without any activity. Usually there is also the option to terminate the "call" after so many pings as well.
If your BBS init or hang-up/restart string has ATZ at the start of it, then anything that was not saved using AT&W would be reset. It's not uncommon to see +++ ATZ being sent to the modem after disconnecting. ATZ is the command that re-loads the settings. You could set S73 to 88 and see that it is 88 with AT&V, and if you then typed ATZ and looked it would be whatever value was saved permanently.
