Hi,
I would like to ask how to release the access permission of COM port
for non-root users. I've tried to change the access permission of /dev/ttyS0
to crw-rw-rw- and my non-root user can access the COM port. However, I have to
re-set the access permission of /dev/ttyS0 to crw-rw-rw- for non-root access as
the access permission of /dev/ttyS0 is seemed to change back to crw-------
EVERYDAY automatically and mysteriously. Is it possible to set the access
permission permanently?
Thanks in advance.
