LED badge programming via Linux. How?

Question

LEDs

There is an LED badge.
Connected via USB.
Recognized by the system as:
Prolific Technology, Inc. PL2303 Serial Port
Under windows there is a program for loading and there, in principle, everything works.
Essence of a question: how "on the fly" to program the text of a badge?
For example, display the system time.
Existing python solutions recognize the device, report that ALL DONE, but in fact no change.
Who faced with such a device?

Answer 1

https://github.com/KuyaMarc/ledbadge
https://github.com/dcolli/badgeup
for example.
/dev/ttyUSB0 (badge connected) is recognized, the script writes about the successful completion of the operation.
In fact, only what was loaded from under windows remains in the badge.

Answer 2

You should at least indicate the model ...
It's easy to do: put a port monitor under Windows, see what the native program writes there, implement the same functionality on Linux.
