You see a list of directories. Your listing may be different. You can recognize directories by locating a dr on the far left. Softlib is a directory that contains Microsoft software files. Files that have the extension .txt are ASCII files. Files that have a .ZIP extension are compressed. You need a utility like PKZIP to unpack the file. If you key in the command get filename, it will transfer the file to your default directory. If you key in get filename -, the file name followed by a hyphen acts just like the TYPE command. These commands are Unix commands. As you can see, DOS commands borrow much from Unix commands. If you wanted to transfer a binary file (.EXE), you would key in:

binary get file.exe ascii

You key in ascii to return to text-file mode.

12.26 Telnet

Telnet is a connection to a remote computer which makes your computer act like a terminal on the remote machine. This connection type is used for real time exchange of text. Telnet makes your computer into a dumb terminal. It is called a dumb terminal because each time your press a key on your computer, your computer does nothing except transmit your keystroke to some other computer on the Internet. The software performing the commands actually runs at the remote computer and not on your computer. Telnet operates in a client/server environment in which one host (the computer you are using running Client Telnet) negotiates opening a session on another computer (the remote host, running Server Telnet). During the behind-the-scenes negotiation process, the two computers agree on the parameters governing the session. Technically, Telnet is the protocol and is the terminal handler portion of the TCP/IP protocol suite. It tells the remote computer how to transfer commands from the local computer, on which you are working, to another computer in a remote location. Thus, Telnet lets you become a user on a remote computer. Both computers must support the telnet protocol. The incoming user must have permission to use the remote computer by providing a user name and password. Telnet can be used by a system administrator or other professionals to log on to your computer and trouble-shoot problems on your computer. However, Telnet is also most commonly used for connecting to libraries and other informational public databases. You can use a Telnet client to access hundreds of library and government databases. You begin the session in a Command Prompt window.
