Yes, I'm wiring the grounds together, thanks. I used the old LED trick to test that the STUART is sending when I tell it to, and it appears to be sending, therefore I've verified my setup is correct. The only remaining question is whether or not I'm sending what the motor controller is expecting. Originally I've tested the motor controller circuit with a basic stamp microcontroller that I have and the bit pattern I'm sending is the same as I used with SEROUT on the basic stamp. So here are my questions: 1. I've used termio to set the baud rate but how do I ensure 8 bits, no parity, and 1 stop bit? 2. Is it possible that the STUART on the gumstix is inverted (or perhaps the basic stamp is)? 3. Is there anything else that could be different from the basic stamp SEROUT?

I don't believe not connecting RX will result in anything not working; however, you should be wiring the ground lines together. -chris ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
