Question Serial Communication

Hi All...
I am using Mandriva Linux 2010.2....
I am trying to use minicom in my PC...
While trying the minicom command it gave me a error that it is unable to lock ttyS0.... I cant find why.... And if i try to use it it is only available in root user and not in any other users... This is the problem that i am facing...

If i am wrong please help me with the configuration...

Check the permissions of the device :

ls -l /dev/ttyS0

Well, if the device belongs to root:root with rw only to root, you have to.

Make it rwrw-- for root:users
