E.g., on a UNIX system you might type:
% set term vt100
to tell the other system that your communications software thinks it is a VT100 terminal (a very common choice for emulation programs).
If you don't get this exactly right, your telnet session will "sort of work". It's probably not worth spending a lot of time on this problem for a brief contact with the other computer. If you are going to work on the remote computer every day, however, you will want to get it right. Most "flaky" behavior can be traced to this problem.
<Section 5.3> File Transfer Protocol (FTP)
It is easy to transfer files over the Internet using a special protocol called FTP. FTP takes the place of programs like XModem or Kermit that may be familiar to you if you use a bulletin board service. Now, you might ask, if FTP transfers a file, what is the differnce between sending E-mail and FTP; why prefer one over the other?
First of all, FTP avoids certain restrictions on the type of file sent; in particular, you can send binary (non-text) files like programs and pictures; and you are not restricted to any particular length, as is often the case with mail programs.
Not only that, with FTP you can "browse" a directory of files before choosing one. You can move up and down the directory hierarchy and list files, looking for the one you want.
Finally, FTP lets you get places that you may not have an account (or a friend to send you mail). The method for doing this, called "anonymous FTP", is described in the next section. There are several hundred "anonymous FTP sites" worldwide, with large collections of programs, textfiles, and graphics. Anonymous FTP is the Internet equivalent of publishing—a very important topic indeed.
