Minicom on (OK, ancient) Mandrake - permissions

Hi, first of all, I admit I'm using Mandrake 6.0
Yes, I'm thinking of changing/updating, but maybe
not on this machine. I've tried everything I can
find to get the minicom program to run for a user,
not as root. (Running as root isn't a good idea, no?)
I've checked the permissions on the modem, /dev/ttyS1
I've set the modem in the minicom setup to be /dev/ttyS1
and not /dev/modem (which has different permissions)
/dev/ttyS1 has root for owner tty as group
my user (say its dauser) has tty in his/her groups

Still, when dauser tries to run minicom, it gets
this permission denied message.

There's supposed to be a file in /etc/minicom.users
(There is a dosemu.users file there) I put one there,
following the sample in the minicom man pages
with the line dauser dfl or dauser dfl ttyS1
It still doesn't work. I've looked in other places
wher this minicom.users might be, and its not there. (i.e.
running minicom -s (for setup) doesn't generate it.
This is embarassing and also I can't think of anything else
to do. I may be back asking this same question later for
another version (less antique) or another distro. I'd still
like to solve this one. Any archaeologists around?

I assume minicom works for you just fine as root. You are correct in setting the serial port, but have you checked the permissions on the minicom file itself? I used minicom yesterday and here are my permissions
-rwxr-xr-x 1 root uucp /usr/bin/minicom
c-rwxrwxrwx 1 root uucp /dev/ttyS0

As a regular user I can use the command minicom -s
My minicom ver 2.00.0 (came with RedHat 9)
Hope this helps!
