I was never into the BBS scene, because outside North America, local
phone calls cost money. So you paid for every minute you were online
-- quite a lot.

I used (and still use) CIX ( which was a sort of UK
version of BIX, and used offline readers -- you dial up, it sends your
comments, zips & grabs all your messages, and disconnects, as fast as
possible to keep the phone bill down.

But AIUI later-era DOS BBSes often used DESQview to allow multiple
multitasking user sessions, and the BBS sysops were often early
adopters of OS/2 2.

So DOS <> no multitasking...
