There is a device connected via USB, which provides data via the Serial interface (ie the device gives data as a COM port). How can I read the data that is issued?
usb / probe device sees.

I've used either MiniCOM and GTKTerm so read data from serial ports before. These work well if you just want to read the raw serial data.

Most programming languages have a way to read from serial ports too. For example the PySerial module allows python to read from serial ports. You'd use a programming lanugage and it's serial port 'library code' to do more complex interactions with the serial port. For example displaying a graph of the data from the serial port rather than just seeing the text scroll on the screen.
