ACIDMAN is an acronym for Amiga Caller ID Manager. It is a database and more program for people who have Caller ID modems, and also subscribe to a Caller ID service through their local phone company. For those of you who do not have Caller ID, fear not. ACIDMAN also comes with ACIDTEST, which will allow you to put ACIDMAN though it's paces, and determine if Caller ID is something you might like, and if ACIDMAN would be useful to you.
