You need permissions to access any files on linux. Device nodes are files, too. This is what it looks like on debian: h...@technical09:~/source/linux/linux-2.6$ ls -l /dev/ttyS* crw-rw---- 1 root dialout 4, 64 2009-11-03 13:27 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 2009-11-03 13:27 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 2009-11-03 13:27 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 2009-11-03 13:27 /dev/ttyS3 This means that I need to be part of the dialout group (or root) to be able to read/write to these files. You can see the group information in /etc/group.
