Hi. I'm trying to set up a class 2.0 US Robotics modem to handle faxes. I'm using efax-gtk on Mandriva Free 2008. The modem connects ok, but periodically I get the error: 'efax-0.9a: 19.30.27 Error: can't open serial port /dev/ttyS0: Permission denied efax-0.9a: 19.30.32 finished - unrecoverable error'
As su, chmod 777 /dev/ttyS0 fixes it, but only until it happens again. ttyS0 appears to be owned by root. It seems to me maybe it should be owned something/someone else to fix this permissions problem but I don't have a clue who. Can anyone put me right on this please? Dave Cooper
