You could create a file /etc/security/console.perms.d/55-serial.perms with something like: # Rule to give access to the first serial port. <serial>=/dev/ttyS0 <console> 0600 <serial> 0660 root.uucp You could change the <serial> line to give access to the first four serial ports like this: <serial>=/dev/ttyS[0-3] Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
