Would it be possible to:
- connect a USB FTDI TTL-232 cable like this from Sparkfun https://www.sparkfun.com/products/9717 to a RouterBOARDs USB port OR use normal USB to serial cable
- configure the port settings for the USB port that the serial device needs via System/Ports such as baud rate, parity and stop bits.
- use /system serial-terminal usb1 to send/receive data to the device much the same way serial ports on USB modems do?
Obviously the serial device can’t be complex and has to be simple. I know some people have a router connected to an Arduino board but using SSH access.
Would this approach work do you think? Has anyone tried this before?
