Terminal Emulator

The terminal emulator program was written as a job assignment. The program
was designed to emulate a WYSE-60 terminal attached to a UNIX machine. The
terminal was to be able to handle the escape and control sequences sent to
it by a program drawing graphics under CURSES.
I designed the program with the idea that to emulate another terminal one would
only need to modify a termcap like file. I created a structure called
emulate[] that contained all the termcap identifers. I match these identifers
to ones found in the .cnf file. When I find a match, I have the escape
sequence needed to perform the command.
Due to time, I was not able to make the program totaly configurable by the
.cnf file. There are some 'hard coded' escape statements that must be
modified to make the program perform as say a VT-100. I think the changes
are small and shoud be easly modified. Someday I hope to get around to fixing
the program so no program changes will be needed. You have all the code so you
may make whatever changes you wish. If you improve it, please let us know.
To run the program enter 'win term'. This will bring the program up 'empty'.
You will need to load a configuration file. Try 2.cnf for COM2. Once the file
is loaded it will connect to the port and you should have access to it. The
menu item 'commands' should turn to normal from grayed but the change does not
take place until a paint is done. You can select it when it is grayed.
That is the only problem that I know of at this time.
This is the first release and I am sure I will be making changes to it as I
can. Thoes of you that may wish to improve in it may do so but please keep
the rest of us informed. Someone may wish to write file transfer utility into
it, I have no desire to get into it at this time.
Have fun
