=== Use 'cat' utility ===
If by any changes you do have a '''Linux''' computer, a '''Raspberry-Pi''' or an '''Apple''' computer then you can easily capture the serial data with the {{fname|cat}} command line utility.
Before using {{fname|cat}}, we do need to identifies the computer device attached to the USB-Serial connection.
The {{fname|dmesg}} command line tools inspecting kernel messages can greatly helps to identify the device name.
In the following capture, it is possible to identify the newly plugged USB device as '''ttyACM1''' (so /dev/ttyACM1)

Now, we can use the following command line to capture the message on de device.
<nowiki>cat /dev/ttyACM1</nowiki>
and viewing the Base Station messages appearing on the screen.

=== Logging data to file ===
Linux operating system (and alike) allows the user to easily and quickly redirect output (like output of {{fname|cat /dev/ttyACM1}}) to a file.
Key-in the following command:
<nowiki>cat /dev/ttyACM1 > log.txt</nowiki>
will instantly redirect everything coming from {{fname|/dev/ttyACM1}} to the file {{fname|log.txt}} .
Press CTRL+C to stop 'cat' and the redirection. The file 'log.txt' is now fully available for data treatment.
A [https://github.com/mchobby/cansat-belgium-micropython/blob/main/mission1/cansat2.py log.txt sample] is available from the GitHub repository.
