How can non-root users access serial ports

Hi,
        Does anyone know how ordinary (non-root) users can use the serial port devices /dev/ttya and /dev/ttyb? I've been testing a modem installation with kermit (hoping to get ppp up) and if I'm not root I get refused the use of the serial devices.

        Thanks for any hints/ information on this topic.

Make kermit set uid to uucp:

-rws--x--x   1 uucp     uucp      542372 Aug 31 21:26 kermit

1. run a non-root user's program from a non-root user

Hi Folks,

Here is the problem.

I have user A and user B (non-root users)

I need for user A to initiate a job as user B. How can this be done?

As you know, I can do this as root. I can start a process from root as
another user in the system (cron jobs come to my mind!) Is there a way
to do this for non-root users? I believe I need to be able to do
something like  as user A
"su - B" without being prompted for password.

Appreciate suggestions in advance.
