echo doesn't try to translate anything unless you tell it to. You can send arbitrary ASCII characters with echo like

Code:
# ctrl-Z
echo -en "\x1a" >&5

The -e part tells it to convert \x codes into ASCII characters. -n tells it not to apppend a newline.

I also have a suspicion this fd-opening thing is only working because 'echo' is a bash builtin so doesn't need to launch a new process. Try to avoid pipes and such to avoid unexpected problems writing to the serial device..

Code:
stty: /dev/ttyS3: unable to perform all requested operations

Did you make a typo? That's not the device you were using before.
