I'm trying to start AHMI on the raspberryPI3 but I always get this error as soon as I close the application that does not communicate:
System.IO.IOException: Descrittore di file errato
at System.IO.Ports.SerialPortStream.ThrowIOException () [0x00000] in <filename unknown>:0
at System.IO.Ports.SerialPortStream.Dispose (Boolean disposing) [0x00000] in <filename unknown>:0
at System.IO.Ports.SerialPortStream.Finalize () [0x00000] in <filename unknown>:0
I'm connected via usb-serial adapter and tried to set it on PORTNAME com1, com2, usb1 but I get the same error result from the raspberry
