[Wine] Serial Woes

[Larry Lohkamp]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

My setup is the standard one generated by the Suse RPM.  The links in
the dosdevices directory for hardware access are owned by root, and
locked to ordinary users. I can su to root and change the permissions.
This allows my programs to access the serial ports, but it is not
persistent. On reboot, the links are again locked. I tried deleting
the links and creating new ones as the ordinary user. Again, this is
not persistent. On reboot, root again seizes control of the links and
locks out other users. Since I am the administrator of this machine, I
can kludge my way around it by changing the permissions every time I
start up the computer, or I can be stupid and run everything as root.
Neither is a spiffy solution. If you know where in the startup scripts
root is making a nuisance of himself, I appreciate enlightenment on
fixing it.
