- This is st52, a vt52 terminal emulator for the Atari ST computer.
- This program is by Nick Castellano (entropy@ai.mit.edu) and is released
- as freeware. (C) 1991 Not Proud Programmers. Developed in GNU C, a product
- of the Free Software Foundation.
-
- You might ask, why did someone bother to write such a useless piece of
- software? There are countless terminal emulators with all sorts of features
- and capabilities. The answer is simple: MiNT. In case you don't know, MiNT
- stands for MiNT is Not TOS, a multitasking operating system by Eric R.
- Smith. One of the programs you can use with MiNT is mgr, a windowing
- interface developed by Bellcore or use on Sun workstations. I wanted a
- terminal emulator that could run in an mgr window. Unfortunately, all the
- emulators I have want to hog the whole screen and make GEM calls and such,
- so none of them work well with mgr. Since you can emulate the ST's standard
- vt52-compatible text display inside a window with vt52.prg (distributed with
- MiNT) I decided to write a very simple vt52 terminal emulator that would
- work under mgr as well as TOS with or without MiNT.
-
- This program is actually not a vt52 emulator at all--it is a dumb terminal
- program that does (almost) no processing on transmitted or received text.
- However, as I mentioned earlier, the standard ST display is vt52-compatible,
- so the net effect is that you get vt52 terminal emulation. Of course you
- can also use it as a "dumb" terminal to call bbs's and such.
-
- To start st52:
-
- From GEM: Double click on st52.ttp and press return when the parameter box
- comes up. You may rename it to st52.tos to avoid the dialog box, as this
- preliminary release doesn't take any parameters.
-
- From a shell: Add the directory st52 is stored in to your PATH environment
- variable, then type "st52" or "st52.ttp", depending on what shell you use.
-
- From mgr: Open a terminal window and type "vt52". When the mgr vt52 window
- is ready, type "st52" to start the communications program. Alternately,
- type "vt52 st52" to do it all in one step.
-
- I have swapped the Backspace and Delete keys. That is, the Backspace key
- will send ASCII 127 to your host, and Delete will send ASCII 8. This will
- be an option in future releases.
-
- There are only three special keys in st52:
-
- Alt-C: Configure. Basically self-explanatory. Just press Alt-C and follow
- the prompts. Currently the only option you can set is communication speed
- (bps rate). In future releases you will be able to set other RS-232 options
- such as parity and stop bits.
-
- Alt-Q: Quit.
-
- Alt-Z: Stop. Works only under MiNT.
-
- A few useful termcap entries from various sources are included in the file
- termcap.st (including entries for mgr, which might allow st52 to be used in
- an mgr window without vt52.prg, but I haven't tried it yet). I've been using
- the first entry with no trouble; your mileage may vary.
-
- Make sure when using MiNT that you only have one process at a time talking
- to the modem, otherwise characters from the modem will be distributed
- randomly to each of the processes.
-
- Note that the arrow keypad and function keys don't do anything useful in
- this program.
