You can remove the colour control codes from the output stream using ansifilter.

Read from Serial Port

There are two options to read DALI frames from a serial device. The first option is to open a pipe from the serial port. Remember that you have to initialize the serial port to use the correct baudrate, This example reads from a serial port connected to ttyUSB0 using a baudrate of 115200 Baud.

stty -F /dev/ttyUSB0 115200
./dali_mon < /dev/ttyUSB0

The other option is to use the serial-port command line parameter. Note that the default baudrate of 500,000 baud will be used:

./dali_mon --serial-port /dev/ttyUSB0

Alternatively, you can use the short form of the same parameter.

./dali_mon -s /dev/ttyUSB0

Or, you can store the serial port into an environment variable and use the ususal approach to make this a permanent setting.

export DALI_SERIAL_PORT=/dev/ttyUSB0
./dali_mon
