SSTERM Version 2.00   (3/24/87)

	SSTERM is a simple split screen terminal program designed to be used
on GEnie (General Electric Network for Information Exchange).  It does not
have some of the features needed to make it useful as a general purpose
terminal program.  The most notable of these is the lack of any means of
saving text to disk.

	The program works as follows:  All text received from the modem is
displayed on line 20 of your terminal and is scrolled upwards after each
carriage return or after the 80th character is displayed.  Text from your
keyboard is displayed on lines 22 & 23 starting with line 22. They are in
your alternate video mode if that is supported by your terinal.  The maximum
number of characters typed before a carriage return is 159, if you enter more
than that number the display will be messed up until you type a carriage
return. (The modem will still send the proper data, only your display is
affected.)

	There are three control commands, all of which are prefixed by the
ESC character.  The commands are: D or d - disconnect the modem from the phone
line using the DTR line. (This is one standard way to disconnect a Smartmodem
type of modem.)  X or x - Exit from SSTERM back to CP/M.  And a second ESC
which returns you to the terminal program and clears the screen. (This is 
useful if you strike ESC by mistake.

	SSTERM is written for the Columbia Data Products "Commander M64" which
is also known as the Conkey-64 or "Shoebox".  If you are going to use SSTERM on
a M64 then the only area of the overlay file which needs to be changed is
the section for terminal control commands.  If you are not, then you will
probably have to change the port addresses for the console uart and the
modem uart. If your system does not use the 8251 usart then you will probably
have to change the usart initialiazation section and the section containing
the routines for usart I/O.  I suggest that you start with the ADM-3A
overlay file (ADM3OVL.ASM) because it is the least hacked up of the two files
included with the library.  The other overlay file (VT100OVL.ASM) is for
VT100 compatable terminals which can run in the VT52 mode.  It contains two
patches which switch the VT100 to VT52 mode and back to VT100 mode on exit
from SSTERM.  You may want to examine it to see one way to include patches
in your overlay.

	Also included in the package is an overlay for the Kaypro II system
since that system does not use a console USART.  This overlay was developed
by William Duerr (B.DUERR).  This overlay can be used as the basis for other
systems which do not use console USART's.

	I have included the assembly language listing of the basic SSTERM
program in the library for those people who want to hack it for other uses
such as for RTTY conversion.

P.S. If someone can provide me with detailed information on how a memory
mapped system is set up I will try to make a version of this program for
systems using memory mapped video.
