I have my modem set up for word commands and ProTERM 2.01 realizes that I've
hung up...Maybe 1 in one hundred times of hanging up, probably less, ProTERM
doesn't realize I've hung up but that's usually because of some weird carrier
loss for an unexplained reason (i.e. not hanging up from a bbs the standard
way).

I only have my init string to "AT" because I don't like my busy detection on
because my modem (an EasyData 2400BD) sometimes thinks that a really LOUD
ring is a busy signal...

It just seems like the BUSY detection on modems is fooled sometimes...Since
I call the UNIX system (which is never busy), and other bulletin boards
usually in the middle of the night when they're not too busy, it doesn't
really matter to me.
