[olug] What am I forgetting

[Tom]

One of the guys at work brought in a book and I was going through the
commands and saw that.
But before I could try it I got your note below and it worked great, thanks.
I guess put that as another notch and note on my list.

Tom,

Try running 'setserial /dev/ttyS0' as the non-root user you want to run
your application with and see what you get.

Default:

crw-------    1 root     uucp       4,  64 Sep 19 08:05 /dev/ttyS0

result:
>$ setserial /dev/ttyS0
/dev/ttyS0: Permission denied


Here is what mine looks like after I changed it
(command: chown jlarsen /dev/ttyS0):

crw-------    1 jlarsen  uucp       4,  64 Sep 19 08:05 /dev/ttyS0

>$ setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4


This should allow the given username to access the serial port.
