Go down to radio shack and get a couple of connectors. Roll you own.
In fact, as I tried to describe in my above post, the way the MAX202 is wired in the EasyPic6 to the Female DB9 connector it does crossover the 2 to 3 and 3 to 2 pins from the cable so that the signals are correct when they get to the MCU. See the schematic I posted above.

Thanks so much for all your help with this. I would appreciate an explanation of my question regarding HSERIN [X] versus HSERIN [DEC X].
