- ReadMe for UniTerm V2.0c 016 <-|
- ---------------------------- |
- 5.5.88 |This number is displayed on the
- 'About UniTerm...' dialog box and
- indicates the "Edit Number"
-
- Changes 2.0b to 2.0c
- --------------------
-
- General: A lot of the oldest code in UniTerm has been redone. Some things
- should be even faster now.
-
- The 20ATO20C.TOS program will convert 2.0a/2.0b setup files
- to 2.0c format, remote commands will be disabled, clipboard
- size set to 2kB and NRC to ASCII (turned off).
-
- The delay time parameter now additionaly affects:
-
- start/end of transfer strings in ASCII file upload
- the dialer
- macro processor send command
- single-line editor.
-
- Keys moved: View History buffer (NEW!): <Alternate><V>
-
- History Control: <Alternate><S>
-
- Mouse cursor control now uses a double click with the
- left button.
-
- UniTerm will no longer let you exit from the `Help' menu
- if you still have desk accessory windows open. The deeper
- reason for this is a AES deficiency.
-
- Terminal Emulation:
-
- NRC character sets implemented, they will naturally be
- slower than the straight ASCII mode (the Dutch and
- Portugese sets are not completly implemented).
-
- I'm too lazy to list the corresponding escape sequences,
- will be in the manual.
-
- NRC mode can also be set in the 'Terminal 2' dialog,
- selecting [ASCII] just turns NRC mode off, selecting
- one off the NRC sets, map the set into G0 and G0 into GL.
-
-
- *********************************
- *Macro processor: COMPLETLY NEW!*
- *********************************
-
- The two modi (function key - macro file) are now more different, the %
- command introducer is now only needed (and allowed!) on the function keys.
-
- No more absolute line numbers (labels instead), additional integer and
- string variables.
-
- No more boolean constants, use 0 and 1 intstead (for FALSE / TRUE)
-
- Commands are no longer case sensitive.
-
- Common features:
- ----------------
-
- Built-in functions:
- -------------------
-
- add(int1,int2) returns sum of int1 and int2.
-

- *****************************************
- * History buffer viewing *
- *****************************************
-
- Needs at least 25kB of reserved system memory.
- Start with <Alternate><V>.
-
- <ClrHome> Display top of buffer
-
- <Insert> Display bottom of buffer
-
- <UpArrow>,<DnArrow> Scroll line up/down
-
- <RightArrow>,<LeftArrow> Page up/down
-
- The mouse clipboard functions work the same as in normal mode.

- ////////////////////////
- Incremental change list:
- ////////////////////////
-
- V2.0c 002
- ---------
-
- The default history buffer view mode now displays CR and LF as spaces,
- this makes cliping stuff from the buffer much more useful, the old mode
- can still be used with the command
-
- ViewHistEOL = 63
-
- V2.0c 003
- ---------
-
- Fixed a small bug in the mouse code that caused spurious 'Alt' keycodes
- to be generated.
-
- Put the 'GDOS not loaded' message back in, this uses the (possibly invalid)
- rule that 'graf_handle' will not return 1 as the workstation handle.
- (As we all know the ST crashes if you try to open a workstation without
- having GDOS loaded....).
-
- To avoid unnecessary contortions in initializing the data structures in
- the view buffer mode, it now just rings the bell and returns immediatly
- if you try to view an empty buffer, the same happens if you try to use
- while in tek mode.
-
- V2.0c 004
- ---------
-
- Fixed a bug in the new Kermit checksum code, the two character checksum
- wasn't masked properly.
-
- V2.0c 005
- ---------
-
- Saved a few bytes (11 to be exact).
-
- V2.0c 006
- ---------
-
- Fixed a really old bug in the routine that gets filenames out of dialogs,
- it sometimes inserted the '.' in the wrong place.
-
- V2.0c 007
- ---------
-
- Improved the actual time processing of a ESC character takes (it now takes
- 0.17 mS).
-
- V2.0c 008
- ---------
-
- Fixed underline cursor. Fixed a bug in the line breaking code for viewing
- the history buffer. Moved the 'Help' dialog up a bit, so that it hopefully
- doesn't get truncated anymore on a color screen.
-
- V2.0c 009
- ---------
-
- Fixed a VERY nasty bug in the delete_in_line code.
-
- V2.0c 010
- ---------
-
- -Left and right mouse buttons work normally now for desk accessories
- and programs that are run from UniTerm.
- -UniTerm now remebers the last text terminal type selected (it always
- did this, it just didn't set it when switching by hand).
- -Fixed XModem checksum bug (just a typo: addi instead of andi), it
- seems as if nobody ever uses this (and I missed it testing)........
- -Fixed autoprint messing up the screen.
-
- V2.0c 011
- ---------
-
- Just cleaned a few things up.
-
- V2.0c 012
- ---------
-
- Fixed minature bug, the device identifcation response in VT200 mode
- should be:
-
- ESC [?62;1;2;6;8;9c
-
- (instead of ESC [?62;1;2;6;8;0c)
-
- V2.0c 014
- ---------
-
- Due to the pleas of Marion Hakanson, I put the %if() control statement
- in to the routine that processes function keys, my luck that I don't have
- to show the code to anybody........
-
- V2.0c 015
- ---------
-
- Fixed some problems that were due to UniTerm not cleaning up properly
- after fatal errors early in the initialization.
-
- V2.0c 016
- ---------
-
- Tiny cleanup.....
