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"
, which was accepted (no error) but does not acchieve anything.
The command was cat'n'paste from the documentation of the manufacturer
of the chip (a GPS receiver module).
I tried different commands. All were directly send to /dev/null inside
the chip it seems...
Is there any other simple straight forward method of writing
successfully to a serial port (only RX/TX are connected) without
dealing with minicom or advanced serial port programming in C?
Thank you very much in advance for any help!
Best regards,
mcc
