This is not completely accurate. I am answering this post using an X-windows
interface via a serial line. The software is exceed/express which is a serial
line extension to Hummingbird's exceed X-windows system (for Windows). This also
requires an Internet connected host which can run host software. In this case,
the host is an SGI Challenge S server. The initial connection is to a modem
pool connected to our university network. The terminal server to which one
connects first allows telnet connection to the SGI host (or any other
host on campus). One then initiates the X-windows session by starting the
host software. Aside from the slower speed, the PC acts like a proper X-terminal.
An alternate scheme, which has just begun here at Penn, is something called
PPP protocol. This also allows pseudo network connection via a serial line,
and allows telnet, ftp, mosaic and netscape operations from a PC via a serial
connection. This also works quite well, but is significantly slower than
a real Internet connection.
Hope this helps
