Hi Jim,

Any chance you could do the following

ls -al /dev/ttyS0


On my machine I get

[EMAIL PROTECTED]:~$ ls -al /dev/ttyS0
crw-rw---- 1 root dialout 4, 64 2008-08-17 22:10 /dev/ttyS0
[EMAIL PROTECTED]:~$

In order to allow my 'user' to access the device I did the following

sudo adduser j0n dialout

[EMAIL PROTECTED]:~$ sudo adduser j0n dialout
[sudo] password for j0n:
The user `j0n' is already a member of `dialout'.
[EMAIL PROTECTED]:~$

Regards
John

I only figured out enough to change the permissions on my
USB
joystick so that each time the device is created I can use
it.  I
had to go into /etc/udev/rules.d/ and change a file in
there.




Ok- I prowled around in the /etc/udev/rule.d file and I figure I am WAAYY over my head on that one. What do I need to look at in the directory and is there a decnt webpage or something that might help me figure that out?
