Thanks, both of you, for your help. I'm able to connect to the BBS via telnet on port 2323. I will need to find a VPS company that gives root access, in
the future.

For now, this is cool! However, I've got a weird ANSI or character display issue going on when I connect via Telnet. (It looks fine in local logins.)

I tried changing the UTF8/CP437 setting, but it made no difference.

Do I need to add ANSI support to the VPS?
