Well, first off, you have to realize that all of the files in the /dev
directory correspond directly to each device installed in your system. If
you want to send data to a device, you have to open() it like a file, and
write() to it. The same procedure goes for reading: open() it and then
read() from it.

What do you mean "get the code 'into' dev/ttyS0 or ttyS1"? Do you mean
upload the actual program into the device?
