Because I need to connect the PTT of my transceiver to COM1 (/dev/ttyS0)
I have done:
# chmod ug+rw /dev/ttyS0
# ls -al /dev/ttyS0 (answer: crw-rw--- 1 root uucp 4, 64 2005-06-05 05:57
Serial port permissions are often allocated to the 'uucp' group. If this is
the case, add your username to the approprate group
So I did:
# groupmod -A henkoegema(myusername) uucp
Still when I open the application which uses that serial port COM1 I still
"cannot open PTT device '/dev/ttyS0': permission denied.
