I built a custom firmware image for the RUT955, based on official, latest openwrt.
Basically works, incl. EC25. But now I need to use RS485 and RS232 for modbus-serial.
Any idea, which of the following devices might be the RS485, and the RS232 (DB 9) ?
console, tty, ttyS0, ttyATH1, ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3 ?
In case, I would build an image using your SDK, which device would be RS485, RS232 then ?
