Arria10 - Send linux command to the CPU through UART without minicom ?

Good morning,

I am using an ARRIA10 Dev kit board which Linux is installed in the SD card and I can access it by using Minicom.

In the embedded linux, I have a small program I could use with parameters.

From the computer connected to the board, I would like to run a command and read the result. (in a C/JS/Ruby program)

for example: from my Ruby program located in my desktop computer, I'd like to send the `cat afile.txt` command in the embedded Linux and see the value of the file.

I didn't find any clue, is it possible ? (I guess so otherwise it's should be pretty useless)

Thank you very much.
