Hi All,

I’m looking for an userspace ‘C’ test code to transfer a file on UART
Tx line and receive the file on UART Rx line to test loopback
supported serial port.

Before sending file on UART . I would suggest you to test sending simple buffer and ensure you receive it correctly.

Can anybody give example of such application?

I am assuming you have correct hardware ,ensure RS-232 RX-TX lines are short.If you are not sure follow below link

Coming to application which tests loop back,there are plenty tools like

1.minicom

2.cutecom etc.

if you want to specific application try below
