Do you have a break-out box to confirm that RTS/CTS are >being driven? => - beagle board According to schematics the board has only RX and TX connected. No RTS/CTS - am335x-evm The schematics say "DNI" next to a resistor on RTS/CTS. DNI stands most likely for "Do Not Install". With a scope it looks like the the wire behind the MAX is open. - beagle bone black Only RX and TX are wired towards the USB2serial device. In short: each device I have has RTS/CTS not working/connected and I can't test HW handshake with HW available. >Regards, >Peter Hurley Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
