The board is for another project. It requires real RS-232 levels. There is a
MAX3232 chip on it. Since the GPS has a 1PPS output, I figured that I might
as well bring it out. There is no documentation on the pulse width or
polarity... it is what it is... I'm probably hooking it straight to the '232
chip without any massaging.
There is also one more available RS232 input pin on the chip. Any preferences
for RTS or DTR? There is a jumper for powering the board from the RI pin (pin
9) of the RS-232 connector.
---------------------
Yes, this is right. But watch the polarity. It is easy to get it wrong.
In RS-232 the controls pins are different from the data pins.
