Here are some of the more popular PD/freeware/shareware terminal emulator and
related programs available.  Use one of these programs for accessing a dial-up
Bulletin Board System (BBS) with your Atari, or for accessing a dial-up "shell
account" with your Internet Service Provider (ISP).  Dial-up shell accounts
are no longer widely available here in the 21st century!  (There is no
general-purpose PPP capability for the 8-bit Atari that I am aware of.)
