Hi,
It is unusual to get questions presently about Minicom now that most have broad band.As my memories of dialup and Minicom are still fresh, shall try help solve your problem.(From the way you have described it you are no novice to Linux.)To start,as root # minicom -s to open its (configuration) menu.By default all users have access to run minicom based on permission set in /etc/minicom.users file.As you haven't please try to obtain it with
# chmod 755 /dev/ttyS0.(for Ubuntu it would be sudo chmod 755 /dev/ttyS0) You can reverify using ,ls -ld to see what chmod did for you.I hope this helps do tell us what transpired.

Is it a modem for web access?

No this is not a modem for internet access, I use it to control and communicate with external devices via RS232. I have tried minicom, and telnet to accomplish this but no luck. I am BRAND NEW to linux, this is not very encouraging, a simple task to use RS232 via ttys0 to external devices seems VERY difficult. Thanks for ALL Your help..
