I'm surprised you didn't come across that one, it's pretty
common.  I might vary it a bit depending on the application:
I know that many Atari serial ports lack DSR, so I simply
use DTR at the remote end to assert DCD.  Some terminals use
DTR/DSR the way that RTS/CTS is more commonly used, so I'd
wire DTR on the terminal CTS on the host and DSR from RTS.
If I knew for a fact that DTR/DSR and DCD weren't used by
the aplication, I might loop them back locally and use 5
conductor screened cable instead of 7.
