Hi Shan,
With the SuSE distros (and you might consider upgrading to openSUSE 10.3), you have to run minicom once as root, set up, and save a default profile. I think minicom defaults to use /dev/modem as the device, and sometimes my Linux did not set up that device. So, before running it as root, determine the actual device the modem is connected to (something like /dev/ttyS0). The only profile setting you really need to make is the setup of the modem device (port, speed, flow control, word length, and stop bits). I am not at a PC with a modem, so I cannot check this, but if you still cannot run minicom as a normal user, or you are denied access to the modem device, make sure your user is a member of the dialout group, and you may need to add them to the uucp group. If you do change the user's group settings, this user will need to log back into Linux again to realize their new group membership.
I think this will get you going. Good luck with it.
