linux - Binary data over serial terminal

Question

My only way of communication with my embedded device is a serial port. By default, embedded Linux uses this port as a terminal. How do I disable this terminal and use the serial link to transfer binary data? I heard of commands like rx and tx but i cannot find them.

I think I can just read() from and write() stuff to /dev/tty but I want to make sure no error messages or whatever mess with my data stream.

Answer 1

Can't you just set the terminal to raw?
