Is it possible to transfer files through serial ?

--- Quote Start ---

Define what you mean by 'serial'? Ethernet is inherently serial, so is USB. 'Serial' from what source to what destination, over what kind of link.

Remember when you ask a question you need to provide as much detail up front if you expect some kind of helpful answer.

Hi,

I intend to use ucos, without ethernet.

So it seems that in order to flash program new images, we will need to use the UART interface.

Serial file transfer can be done with kermit,xmodem,ymodem, but the question is if ucos support this kind of file transfer.

Thanks,
