Hi, I'm stuck with the use of the console port /dev/ttyS0 for inputing data from an external serial device. In output mode all is fine, but in input I see the good signals in osciloscope, but nothing is recieved. On all others port it works good.
If I loop output with input it is the same. I try for instance tail -f /dev/ttyS0... or cat /dev/ttyS0 to see what happens. It looks as if an external process locks the input but I can't find it and there is no error signalled. May somebody have an explanation? Thanks by advance Jean-Philippe BRUNET
