I am planning to connect a Prometheus ProModem 1200 to a DZ-11 port on a PDP-11/24 running 2.9bsd. Can someone suggest which signals are required for "dial-in" support? Is "Ring Detect" used? Please respond directly to me by "mail" ... Thanks! Kenneth H. Jacker ...!{decvax,akgua}!mcnc!ecsvax!khj

The standard modem cable that supports all necessary signals: 1------------------1 Protective ground 2------------------2 Transmitted data 3------------------3 Received data 5------------------5 Clear to send 6------------------6 Data set ready 7------------------7 Signal ground 8------------------8 Data carrier detect 20----------------20 Data terminal ready 22----------------22 Ring indicator 25----------------25 Terminal busy The above should handle your needs, current and future, if hung on any system that supports the standard modem control signals.
