The Internet Adapter (TIA) is an innovative product by Cyberspace
Development, Inc. that allows Unix shell users to simulate a SLIP
connection over a Unix shell account. PPP is not yet supported, but it
is expected to be included when v2.0 is released. TIA is installed on
the Unix host (either in your home directory, if you're a single user,
or with the other Unix executables on the system if it's a site-
licensed copy provided by your provider). When you run TIA on your
Unix host, you can then run WinSock applications on your own machine.
(Note that you still need to install WinSock on your PC.)
For most applications, there is no difference between a true SLIP
account and TIA. But there are a few drawbacks. Because TIA users do
not have a real, unique IP address, applications that require this
(some DCC Chat, Talk, CuSeeMe, Ping, etc.) will not work. Also,
servers, in general, will not work. The latest beta version does have
a port redirection feature, but TIA is not meant for server use. TIA
requires that you have an "8-bit clean" connection to the Internet.
Check the TIA FAQs for more information.
TIA currently costs U.S. $25.00 for a single-site license. They also
have 14-day temporary licenses available. Version 1.04 has recently
been moved from beta to official release in preperation for the
release of Version 2.0, which is currently in closed beta testing.
All future upgrades will be free to registered users.
A) I use Netcom and TIA Why Won't My Newsreader Work?
So far, Netcom is the only large provider that has had this
problem. Netcom does not allow its users to access the NNTP server.
But there is a way around this. A free product also found at:
allows the newsreader to access news off the disk. This program is
installed, just like TIA, in your Unix shell. It is executed at the
same time as TIA by executing "tia -p:119 nntpd." There is also
good documentation in the tiabeta directory.
