fTelnet by Rick Parrish makes it possible for anyone to connect to a telnet BBS on the World Wide Web via any modern browser. It is the most widely used browser based telnet client for ANSI based BBSes. Be sure to write down your login and password once you "REGISTER" for a NEW user account.
Although fTelnet is a great alternative to logging in to a Bulletin Board System. A few people have informed me that they've been having some disconnection issues with the webterm. I've recently removed the
inactivity timeout but your best online experience is still made possible with desktop BBS telnet clients such as Netrunner and SyncTerm.
