Telnet BBS Server is a small Windows program that provides Internet connectivity for Commodore (or other 8-bit) computers. Essentially, it performs these two functions:

Provides incoming Telnet access to 8-bit BBSes.

Provides outgoing Telnet functionality for 8-bit Terminal programs.

BBS Server acts as a modem emulator , appearing as a modem to either end of the connection. This means that the BBS or Terminal program can run without modification. It runs as a background task and uses negligible CPU time.
