As can be read in http://forum.linuxmce.org/index.php/topic,12416.0.html
, I now know that the chain GC100-Cable-Amplifier works fine with RS232 signalling. But how do I debug the process of having the GC100 send messages? I can get an easy reponse from my amp if I send this:
My com port, I think, is on /dev/ttyS_56_0. Baud rate is 38k4.
Shouldn't the /usr/pluto/bin/TestSerialPort be used to get this signal to the amp, then?
/usr/pluto/bin/TestSerialPort -p /dev/ttyS_56_0 -b 38400 -t '\70\77\72\31\0A'
Once this works, I can try more advanced methods of message sending, but even this does... zilch.
Any thoughts appreciated!
