Hi, unfortuniatly I still ahve a almost similar Problem, but do ot get it with this post so far.|
I use the Bananian PI and connected a TTL to RS232 to J12 (Rx-RX, Tx-TX, GND-GND and hoped not to be able to use ttyS3 instead of a so far used Serial to USB Adapter and ttyUSB0.
May be something Need to get configured, I have no clue, however I can not work on the new device ( ttyS3, can anyone help me? I tried already to Change the Connection to RX-TX, TX-RX and Gnd-GND but this has not helped either.
I Need to get the RS 232 work at 57600 Baud, and I Need to free up the USB for another device.
Any suggestion is more than welcome
