VT100 keypad emulation
========================
As there is no numeric keypad on the 3a, TermIt can emulate
it using main keyboard.
The <DIAMOND> key turns on keypad mode for one character.
TermIt allow you generate keypad key with two methods:
1. Using alpha and numeric keys
Ex: for generate keypad <,> key code, press <DIAMOND>,
than press <f> key.

You can cancel keypad mode by <DIAMOND> again.
Also, you can generate VERTICAL BAR simbol with <DIAMOND> and <b>.
Script language
================
Script is ASCII text file, with commands for TermIt terminal emulator.
You can make it, using OPL editor or Word application, but you *MUST* save
file with scripl as TEXT!
Script commands:
WAITFOR "string"
This command waiting for text "string" in
incoming character sequence.
When "string" will be find, next script
command will be executed.
SEND "string"
This command send text "string" to port
(modem, host...).
EXIT
Exit script.
Any other text string in script file will be skiped.
* string parameters *MUST* start and finish by <"> character.
Commands haven't timeout period now. If your script can't execute, because
system answer is not what you want see, just stop script (Psion + f).
While script is running you can enter any commands.
Script example:
! UNIX login script
SEND "ATDT1234567" ! Send dialing command to modem
WAITFOR "login:" ! Waiting UNIX login prompt
SEND "My_name" ! Send user name
WAITFOR "Password:" ! Waiting UNIX password prompt
SEND "My_password" " ! Send user password
EXIT ! Exit script
! END UNIX login script
If after command
SEND "ATDT1234567" ! Send dialing command to modem
you have response BUSY (phone line is BUSY), script will be BLOCKED,
because it waiting string "login:". In this case you can stop script
and run it again, or directly enter command
ATDT1234567
to modem from keyboard. After connecting to UNIX host, script will
be continued.
Support
========
TermIt have support via e-mail only.
Please send me messages about any bugs in TermIt.
Any comments and questions are welcome.
To-do
======
Add "scroll back" function.
Add "brind out" function.
Add Z-Modem protocol to TermIt.
Important!
===========
I wrote this program using OPL. Therefore:
- text output to graphics screen working slow
- screen scrolling working slow too
- bold text output working terrible slow
as result, you can see "Overflow" error in your screen.
For solving this problem you must correctly sets handshakes settings (you must use
the handshaking convention used by the remote computer).
The RTS/CTS working faster, but XON/XOFF work perfectly.
You can disable bold text attributes, for faster text output to screen,
(use Settings/Screen/Bold text Enable/Disable menu).
If you have previous version...
===============================
Just remove old files in /APP/TERMIT/ directory, exclude "TERMIT.REG."
If you have old .INI files in /APP/TERMIT direstory, you will can see warning "field not found".
