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 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.
