You may also declare local variable as static, which will place it into .data section as well.

There are many ways to accomplish that. The easiest one would be to simply transmit hexadecimal representation of every bytes, it means that for 256 array, the transmitted string would have 512 hexadecimal characters.
If you want to have more efficient transmit string, you can use the "uuencode" method which packs 6 bits per characters, but the code will have to handle the bit shifting of every bytes into a 6 bits streams.
