When I send a command directly from the terminal using the command :
echo 1 >
/dev/ttyUSB0 it works and '1' is transmitted to the serial port . But using
php I get the above warnings . I dont understand where the problem is . Is
it a permissions issue ? If not what could be the problem ?
if SELinux is active i would not wonder that httpd can not access
the serial port, however - why are you installing a lammp package
under /opt while fedora has all the needed packages in the default repos?
