I wish I had an oscilloscope because I can seem to get any of the serial TX lines on the breakout board to send the right stuff. "The motor controller expects eight bits at a time (with no parity bit) at a constant baud rate ranging from 1200 to 19200 baud (it will be auto detected). The serial bits must be at logic levels and non-inverted." It is my understanding that the following are true: ttyS0 FFUART (as marked on the breakout) ttyS1 ??BT?? ttyS2 STUART ttyS3 HWUART I've tried all three that are available on the breakout with no results. I've set the baud rate with stty. I have a little c program that uses write() on /dev/ttyS? to send the 4 byte commands. I've looked at the GPIOs for the serial ports, do I need to set them to get them to work? Brian Gregory -----Original Message----- From: gum...@li...

I guess it was a path problem because I'm getting perfect 3.3 & 0 right now. Thanks a ton for the help.
