Internet Adapter

    The Internet Adapter (TIA).  A program
   from Cyberspace Development which runs on a Unix shell
   account and acts as a SLIP emulator.  A TIA emulated SLIP
   account is not quite the same as a real SLIP account but TIA's
   SLIP emulation is completely standard in terms of working with
   MacTCP-based software on the Macintosh (or WinSock on a
   Microsoft Windows machine).

   You do not get your own Internet Address as you do with a
   real SLIP account, instead, TIA uses the IP number of the
   machine it runs on and "redirects" traffic back to you.  You
   cannot set up your machine as an FTP server, for instance,
   since there's no IP number for an FTP client elsewhere to
   connect to.

   TIA's performance is reportedly good, faster than normal SLIP
   in fact, and about as fast as Compressed SLIP.  Future
   releases will support CSLIP and even PPP.

   Cyberspace Development has ported TIA to several versions of
   Unix and more are on the way.

   TERM is a free program which performs a similar function
   between two machines both running Unix.
