Most of the ttyS? and ttys? are root:tty owned, the ones that are root:uucp are all ttyS?. ttyS4 is the only one with owner and group uucp.
The "uppercase" devices (major 4) are serial ports: 4 char TTY devices 0 = /dev/tty0 Current virtual console 1 = /dev/tty1 First virtual console ... 63 = /dev/tty63 63rd virtual console 64 = /dev/ttyS0 First UART serial port ... 255 = /dev/ttyS191 192nd UART serial port But the lower case ttys I don't know. The major is 3... ah, they are PTY slaves, ie, pseudo-TTY slaves: 3 char Pseudo-TTY slaves 0 = /dev/ttyp0 First PTY slave 1 = /dev/ttyp1 Second PTY slave ... 255 = /dev/ttyef 256th PTY slave These are the old-style (BSD) PTY devices; Unix98 devices are on major 136 and above. As for the ownership diference you mention, faxgetty changes it. Try to modify the owner or permissions, you will see how it changes back within the minute. I don't know about mgetty, though. - -- Cheers, Carlos Robinson -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFEQly+tTMYHG2NR9URAs42AKCMw6TUET9VfY7/l8VbWXsEO59VkQCcDHn5 21+FChMgfsxhzbxwxCuN+VQ= =9zFv -----END PGP SIGNATURE-----
