not normally this dense
Well maybe I am, but I don't know if I know more now or less. Heres where I have stumped myself.
Now the 3311 inverts the signal, so should I not use it if I am using the 232 to usb? Or does the cable take care of this? I would stupidly expect the 232 to usb cable to send/receive proper usb signals on the usb side and proper 232 signals on the 232 side.
This sounds like daveH post.

When going to a PC, the serial signal needs to leave the hardware inverted(PIC and components). Does not matter if you are going to a regular serial port or using a USB to serial converter.
The PIC, if using the hardware ports "HSEROUT" sends a TRUE signal so the MAX is needed for the inversion.
If bit-banging, "SEROUT2", then you can invert in PIC software.

Always wear safety glasses while programming.
Thanks guys
I think I have enough to get in trouble with now. I am off to put my test circuit together and start talking (or not).
