 The TERMINAL command allows you to set various modes or parameters
 for your terminal. Following "TERMINAL (MODE IS)", you can type any
 of the following general categories of arguments:

   1. The specific name of your terminal type, e.g. LA30, VT52, etc.
      The list of known terminal types is obtained by typing
      "TERMINAL TYPE ?". Declaring your terminal type establishes
      the proper amount of fill and the applicable modes.

   2. A specific mode (optionally preceded by "NO" to turn it off).

      FLAG       Print a ' before every uppercase character, if no
                 lowercase is in effect.

      FORMFEED   Terminal has form-feed capability.

      IMMEDIATE  Echo each character as you type it.

      INDICATE   Print ^L instead of a form-feed.

      LOWERCASE  Terminal handles lowercase output properly.

      PAGE  n    Terminal stops printing when it reaches the end
                 of a page, or when you type a ^S. To set the page
		 length, give the number n or give a TERMINAL
		 LENGTH command.

      RAISE	 Interpret all lowercase terminal input as the
                 corresponding uppercase character.

      FULLDUPLEX Send to your terminal each character as the
                 program reads it.

      HALFDUPLEX  Don't send to your terminal each character as
                  the program reads it.

      PAUSE END-OF-PAGE  Stop sending output whenever it has sent
                         a full page.

      PAUSE COMMAND	 Stop sending output whenever you type
          		 CTRL/S.

      TABS       Terminal has tab stops every 8 columns.


   3. A value of a certain terminal parameter.

      LENGTH     Set the page length of your terminal.

      SPEED      Set the baud rate for terminal input and output.

      WIDTH      Set the width of your terminal line.
