I have managed to write all characters except nul using write, e.g. 


write(line_write, STX);

will write STX in my bmp file. I have also examined the file in an HEX editor (plug-in to notepad++) and I can see 02 instead of STX. However when I use 


write(line_write, NUL);

neither the bmp file in notepad++ nor the HEX editor have any nul/00.
