Hi,
I want to send commands to ttyO1 (serial port on an embedded system).
The commands are one line each and terminated with CRL/LF (aka "DOS").
Since this will be done from a batch script, it should be possible
via commandline tools and non-interactively. The serial port is
already setup up the right way.
I tried
echo -n"blablabal\x0a\x0d"
Firstly, this command is missing the -e switch. Secondly, the order of
the control characters is wrong. I would suggest the use of printf as it
has fewer pitfalls.
# printf '%s\r\n' "command"
--Kerin
