I tested this board on a Windows Vista machine. It is deployed in the exhibit directly connected via RS232 to a MakingThings Make Controller. I used hyperterminal in order to directly send commands to the board when testing in Windows. I actually never read the status of relays. In development I always used a fire and forget paradigm. So I have only ever used one-way communication with the board! I know the Windows debugging program allows you to read the status of the relays; but I don't ever recall trying to read them directly from hyperterminal. Are you using Minicom on your Linux machine? Is it possible that the character encoding is set to something different then what you can use to actually see the ASCII numbers? In Hyperterminal I would always get weird characters back because I couldn't ever configure it correctly to just display the ASCII numerical values. If I remember correctly my board echo's an ASCII numerical value back every single time I enter a valid command in order to acknowledge the receipt of the command. Are you at least seeing these echo's? Hi Kyle.

I am able to send commands and open and close relays with no problem, but in Linux, only 1-way communications is working! I can not read voltages or the status of relays. If you are using this board with linux, how did you go about getting 2-way communication working? Thanks!
