Hmm, out of ignorance, ('cause I wouldn't gainsay you, Greg!) why? Carrier 
detect is pretty modem-ish, but my simple understanding is that when using 
a null modem, you want to connect DCD to DTR and the same for DSR. I've 
even built cables this way and they worked. It's all just non-magical 12V 
low/high.  That way you've got a "high" signal telling you "Yeah, it's 
cool to talk. We're connected." For a modem, that has the additional 
meaning "You've got a carrier signal" rather than just "The cable got 
plugged in.".

Straigten me out, guys. Am I wrong?
