Gimme a good db25 for the mac. I recently posted the pinout of the modem cable for Mac that came with my Prometheus ProModem. It did include provision for DCD, namely Mac mini-DIN-8 pin 7 to the modem (DCE) DB-25 pin 8. I have now checked out my Hayes-brand cable (which I bought expressly to go with a borrowed Telebit T2500). It is identical to the Prometheus cable, except it does _not_ provide for DCD.
