Open serial port (if needed) and init reader

port¶

Tries to open usb serial ports "/dev/ttyUSB*" and serial ports "/dev/ttyS*"

  my $serial_obj = $self->port;

To try just one device use "RFID_DEVICE=/dev/ttyUSB1" environment variable

If you want to define serial connection over TCP socket, you have to export enviroment variable "RFID_TCP=hostname:port".
