You may need CTS or DTR active for the other end to accept data and respond. Are you sure the CNC machine doesn't need a "hardware handshaking" protocol? If you have uart1 talking to uart4 on the Beaglebone, that says the problem is the physical connection and/or the protocol to the CNC machine. Is the CNC machine wired to be DTE or DCE? At this point I think you need help from the CNC machine's documentation, or from someone familiar with that particular machine. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
