Answer 2

Martin Taylor
thanks for your complete answer
Im working with a customized board which is not an arm board but has arm processor as its core and in its datasheet, it has an rx/tx pins and wanna send commands via these pins but as you said, now I understand that libraries like uart.h are not standard libraries in C.

I don't think you are gonna get answer for that here. Ask it on stack exchange. They have much wider community.
