Hello I have tried to communicate my Beagleboard C5 to my laptop via Serial port.
I had one USB to Serial adapter, I bought it in eBay, dmesg shows:
[ 9946.816413] usb 3-2: new full-speed USB device number 3 using ohci_hcd
[ 9946.983238] usb 3-2: New USB device found, idVendor=067b, idProduct=2303

[ 9947.008154] usb 3-2: pl2303 converter now attached to ttyUSB0
I also bought one serial cable, normal serial cable:
Serial RS232 DB9 Female to Female 9-Pin Cable 5ft,SR
I also bought one ribbon for Serial RS232:
Motherboard Com Port Serial Ribbon Cable bracket RS232
I have used minicom and GNU Screen but don’t works.
Did I bought somo bad component?
