The serial port device should be owned by root, and belong to the dialout group, with both the owner and the group having read and write permissions. You can verify this like this: > ll /dev/ttyS* crw-rw---- 1 root dialout 4, 64 Oct 18 01:21 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 Oct 18 00:28 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 Oct 18 00:28 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 Oct 18 00:28 /dev/ttyS3 crw-rw---- 1 root dialout 4, 68 Oct 18 01:14 /dev/ttyS4 crw-rw---- 1 root dialout 4, 69 Oct 18 00:29 /dev/ttyS5 crw-rw---- 1 root dialout 4, 70 Oct 18 01:28 /dev/ttyS6 crw-rw---- 1 root dialout 4, 71 Oct 18 01:10 /dev/ttyS7 Yeah, I've got a lot of serial ports! :-) The column that says "root" is the owner. The column that says "dialout" is the group. The second and third characters are the owner read/write permissions (r or w indicates permission, - indicates no permission). The fifth and sixth characters are the group read/write permissions. You can run "system-config-users" as root, and add your user account to the dialout group. You'll need to log that user out and back in after making that change.
