Re: USER can't use Modem

[Guy Fraser <guy@xxxxxxxxxxxx>]

Add the user to group uucp.

That should take care of it.

As you can see below only user root and group uucp can access
the serial ports.

crw-rw----    1 root     uucp       4,  64 Aug 30  2002 /dev/ ttyS0
crw-rw----    1 root     uucp       4,  65 Aug 30  2002  /dev/ttyS1
crw-rw----    1 root     uucp       4,  66 Aug 30  2002  /dev/ttyS2
crw-rw----    1 root     uucp       4,  67 Aug 30  2002  /dev/ttyS3
...

Do NOT change the permissions or ownership, or you will create security 
problems.
