I am posting this message on BBS software that runs on telnet, and http, too. I actually run three boards... two are meant specifically for telnet (and one of those runs on a Pi), and the third runs they same DOS BBS package I have used for 30 years now. It can accept dial-up and telnet calls.
Yes, if it is set up correctly or offers http natively.
