But mostly, as I said, I get garbage, if anything. Getting a response is half the battle, so you are halfway there. The symptoms are of a baud rate mismatch (115200 8N1, on both sides; unsure of flow control). Or perhaps there is some daemon on the serial port you've forgotten about (does plptools have such a daemon?). Also try minicom on one side and just "cat /dev/ttyS0" or "cat /dev/ttyAM1" on the other. Keep poking at it, it will come around. B.D. |
