VAXterm document for version 2.4. Sun Apr 22 18:50:55 1990
What is VAXterm?
VAXterm is very simple terminal emulator for professional
usage. I wrote this to make it possible for me to use VAX
computers with my Amiga. However I found out that I'm not the
only Amiga owner who has access to VAX-computers.
The user interface is desinged for people who are used to using
traditional terminal enviroment. There are no pull down menus.
Suggested usage
VAXterm can be used with any host computer which takes
advantage from VT220-features. VMS-orientation refers to
ASCII-file transfer mechanism. Transferring mechanism is
implemented by means of VMS commands. To use this special file
transferring method, you must have error control in your modem.
Without error control, this program haven't got much use
anyway.
Running VAXterm
The VAXterm executable must be located to the same directory,
where the VAXterm setup-files are. VAXterm fonts-directory must
also be there.
ASCII-file transferring
During file transfer terminal characteristics in host computer
must have ReadSync set and PastThru unset (VMS dictionary).
It's the easy part to set these characteristics on your
terminal, but if you use as a host some node that is connected
with slow network connection (DECnet thru modem) to the node
you first log in, sending files directly from VAXterm may be
impossible. This problem can be solved by sending files to the
node connected to modem directly or by means of terminal server
and then copying them to the final destination.
When transferring files, which may contain more than 80
characters per line, the terminl width at the host computer
should be set accordingly.
To set the suitable characteristics for your terminal in host
the computer, you can use function key F4. When F4 is pressed
twice, commands from the file HOST.SETUP will be sent to host
computer. Host computer must be ready to accept DCL-command
from the terminal whenever terminal setup or file transfer
features are used.
The keyboard
All keyboards are based on VT220 keyboard. Unlike fonts, none
of the keyboards are loaded from the separate files. Keyboards
are much the same as Digital's similarly named keyboards. Some
keys required for special purposes, such as C programming, are
added to some of the keyboards. Accent keys are fully
supported. VAXterm does not support character composing, but
if required character is not found directly from the keyboard,
you will probably find it by using ALT-key as a qualifier.
Implementation of the VT220-keyboard:

Special keys:
F1 hold/release screen
F2 printer on/off
F3 set-up
F4 file transfers/host set-up/quit
F5 break
Miscellaneous controls
Right mouse button toggles the mouse pointer and screen gadget
visibility.
When the printer will be activated for the first time, file
PRINTER.SETUP will be sent to printer to modify the default
printer settings.
The commands for the host set-up will be read from the
HOST.SETUP file.
File transfers will work only when the terminal emulator is
logged into the VMS-system. The system must be ready to accept
DCL-command from the terminal.
Serial-port parameters
Parameters for serial-port will be taken from intuition user
preferences. Before using VAXterm you should set them to
correct values using preferences tool.
Known bugs
If the file transfer is attempted to nonexisting directory or
using inapropriate terminal settings at the host computer,
VAXterm will be most likely fatally jammed. Usually VAXterm
will continue normally after double clicking the left mouse
button.
The author
As you might have noticed, VAXterm doesn't have much to offer
for common Amiga user. If you're not such common user, I hope
you like this one. If you got any suggestions or if you are
just interested to get more cheap and reliable software, you
