Hi Kurt, In general, sound cards are handled directly under most DOS environments. You may want to look at the source code for several games to see how it is done.
Another solution is to look at the Allegro library at < http://alleg.sourceforge.net/ >. I haven't used it in several years but it seemed to work nicely for the miniITX hardware I was using at the time. Personally, I have not tried any digital modes on FreeDOS. My personal favorite is fldigi which I run mainly under Linux and occasionally under XP. What sort of support were you looking for? Are you thinking of doing some development?
