I try to develop some hardware which I want to connect to Xcos in Linux
(simply DAQ).
Right now i write macro making a block in Xcos. I can put parameters to my
C library and get date from (loopback). Right now i try to connect to
usb/rs device using this library: http://www.teuniz.net/RS-232/
And get this error:
!Oups. A fatal error has been detected by Scilab. !

Becose i devide program into parts i can use the same source in standalone
application - it's work perfectly.
The problem is probably permission to /dev/ttyUSB. I don't know exactly the
structure of scilab, but i think that the java virtual machine not allowed
to open comport. So the question is: how to workaround it? (for dirty
solution i try to exectue evrything as root, but it has not effect :/ )
Any ideas?
Thanks for any replays
