I have a question related to the serial terminal. I have a Linux computer and I connect to an ARM mini-computer running debian with `screen /dev/ttyUSB0 115200`. From there, I can login and type commands.

That means I can virtually transfer any text file, by creating a file on the ARM through the serial terminal, opening the file in the Linux computer and copy all the text to the opened terminal.

Now, I would like to transfer binary data. My ARM computer doesn't have access to internet and thus, can't install packages. That includes `minicom`, sadly. Besides, it doesn't have `rz` out of the box.

In summary, I can easily transfer everything that is text. Now, I would like to copy a binary file through it. How can it be done?

P.s.: This question extend [Send a binary file through serial terminal](https://unix.stackexchange.com/questions/545339/send-a-binary-file-through-serial-terminal/545367), with a bit more constraints.
