Subject: [gentoo-user] Writing to tty01 (serial port) in simple straight forward way...?!?
Date: Sun, 12 Oct 2014 14:08:02 +0200	[thread overview]
Message-ID: <20141012120802.GA4800@solfire> (raw)

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
