Re: ADT IIC

I'll have to dig out my old hand written notes. I'd tried some off the net too,
but the problem I was having was a fried serial port. Once I changed the mother
board it went together easily.

I'll put something together for you though. I've found that all you really need
is these connected.

Apple  PC

RD      TD
TD      RD

The //c doesn't do handshaking well.

Looking at the din cable end

 5     1
  4  2
    1

to PC 9 pin

wire 2 to 2
wire 4 to 3
wire 3 to 5 - ground

That's all I used on mine with ADT and comm software as NULL Modem.  I think
those connections are right. My notes are just scribbles on scrap paper from
when I made that thing. If you use the PC cable trick you will need something
to test which pin leads to which wire. I didn't have a tester handy so I took a
flashlight bulb, a battery, some tape and 2 pieces of wire and jury rigged my
own. Crude, but it worked.
