Hi there I recently was trying to fix a problem on one of our linux boxes we use to display pictures (like driving a Ferrari and 40km/hr) with X from our SCADA units via a slip line. I was receiving a "Bind - address already in use" error message at the end of the X start up messages. I began to think that the mouse signals were coming out the same serial port as the picture data going in as our screen cursor would scroll across the screen indefinitely out of control and sometimes screen pages also would change out of control. I'm not exactly sure how I fixed the problem but it has gone away (permanently ??). The things I know I have done to fix the problem :- In the XF86Config file I set the mouse to /dev/null (as we are not using it) and because of this now I receive a message "/dev/null unable to get status of fd (inappropriate ioctl for device) but I guess that is OK. I found a lock file in /tmp directory called .X0-lock with the contents being 351. I deleted the lock file but found it was created the same when I rebooted next time. We use Redhat and a uname -r reveals 2.0.36 as the kernel number. I occasionally find that I can run a slip line off one of the serial ports but not the other (this machine being an example of that). Is there a command/utility that can test whether the serial port is OK or is there a file that needs editing. Permissions on the serial ports are the same.
