==========

*Data collected 2026-02-09*

- **BBSes responding**: 1042
- **Unique protocol fingerprints**: 78
- **BBS software detected**: 549 (14 unique packages)

These statistics reflect the most recent scan of all servers in the
`bbslist.txt <https://github.com/jquast/bbs.modem.xyz/blob/master/data/bbslist.txt>`_ input list.
Each server is probed using `telnetlib3 <https://github.com/jquast/telnetlib3>`_,
which connects to each address, performs Telnet option negotiation,
and captures the login banner.

The charts below summarize data from all responding servers.
