So, now that you're using the correct header, it is telling you that the termios related functions expect a file descriptor (not a stdio stream pointer) as their 1st argument. What have you done to fix that?

What does your code look like now?

Have you added code to check function calls for success and to report errors that were detected?

I repeat: What return statement did you add to your function and where did you place it?

I repeat: What terminal characteristics does your scale hardware expect on its communication link to your system?

Thanks.

But, since you don't include <newline> characters in most of your output, it may be stuck in a buffer instead of being made visible
That was it. Put in the \n and everyting worked. I should remember put in error checking and to flush a buffer. Sorry for my stupidity.

BTW - In the Debian distribution that I have, this is what works...
#include <asm/termios.h>
