C The function of this program is to turn on the modem control lines C DTR and RTS comming from the DMF-32. This is necessary because the C DMF-32 port 0 and 1 require carrier detect (pin 8) to be present in order to C work. We achieve this by hooking up a special null modem cable with RTS C (pin 4) strapped to carrier detect (pin 8) so as to fool the DMF-32 into C thinking that a modem is attached. C C Now if we were using a complete RS232 cable with all the wires running C from a DMF-32 to a VT100, this would not be necessary. However, C we typically run only 4 wires, and ports 0 and 1 are unique in that they C will not work unless carrier detect is present. C C The function of this program is to force RTS and DTR high so that they C can be used for strapping to other lines which want to see a high signal. C Both lines are force high so that a general purpose modem fakeout pigtail C can be used: Pin 4 (RTS)-to- pin 5 (CTS) and pin 20 (DTR) -to- pin 6 (DSR) C -to- pin 8 (CAR). Note dip switch 8 on the DMF32 is closed which ties pin 6 C to pin 8 internally.
