minicom: cannot open /dev/ttyS0: Permission denied

[Peter Christensen <christenpet@snip.net>]

I wanted to find a replacement for Windows Hyperterminal, so have tried Seyon 
and Minicom.  I could not get anywhere with Seyon, and found the 
documentation very difficult.  

Minicom, on the other hand, was easy to configure, and as root I am able to 
dial out and connect (with my local public library to access their "card 
catalog").  But when I try it as "me" (not root) I get the error message:

minicom: cannot open /dev/ttyS0: Permission denied

According to the Minicom man page I need to be in the "dialout" group.  I am 
already in this group and am able to use "pon" to connect to my ISP.  Does 
anyone know what else I need to do to use Minicom without being in root?

Thanks,
Peter Christensen
