- UW (Unix (tm) Windows) for the Atari ST
-
- This program was written by Hans-Martin Mosner at the University of
- Dortmund in West Germany. It has since been enhanced by Brad Bosch
- and Brian Katzung at Lachman Associates, Inc., in Naperville, Illinois.
-
- Note that this disk represents a beta test version, and is provided on
- a strictly as-is basis, and we assume no responsibility or liability
- for any aspect of this software.
-
- This version of uw provides only adm31 emulation and the most basic
- UW protocol. The adm31 emulation has been extended slightly. See
- the end of the Features section for a description of the extensions.
-
- Features added by Brad Bosch and Brian Katzung:
-
- o Jump scrolling occurs if screen updates can't keep up with
- transmission from the host.
-
- o The input window may be different than the top window.
-
- o A printer copy of output to each window may be enabled or
- disabled on a window-by-window basis in various flavors.
-
- o <Shift><Help> sends a break.
-
- o There is a menu item to reset flow control if the Atari and
- the host get out of synchronization.
-
- o Fonts "windalt.fnt", "windoth.fnt", and "windtny.fnt" are
- supported in addition to "windstd.fnt". The "windtny" font is
- small enough to allow four 24 x 80 windows on the screen without
- overlapping.
-
- o The smaller system font is offered in addition to the larger
- one. Some of the characters in the smaller font are "improved"
- to increase readability.
-
- o The user may now select whether or not a window will be
- "topped" when a ^G (BEL) is output to it.
-
- o The user may choose to have ^G (BEL) flash the screen, ring
- the bell, neither, or both.
-
- o When not selecting an input window, pressing the right mouse
- button on the menu bar toggles the menu bar sensitivity.
-
- o The close-box works even when the UW protocol is not running.
- This is useful for changing the font size or other options.
-
- o The RTS (request to send) and DTR (data terminal ready) lines
- can be cleared and asserted.
-
- o Function keys can be used and defined up to 40 characters each.
-
- o Function keys and other global option values can be saved and
- loaded. A file called "win.cnf", if present, is read at startup
- time.
-
- o The right mouse button can be used to copy text from the screen
- and send it to a window as keyboard input. Click twice on a
- window border to send copied text. Click once on the boarder to
- select the window for input. Select text by dragging with the
- right button pressed. Inside a border, a single right button
- click selects a word and a double click selects a line.
-
- o Emulation window size can now be selected when a window is opened.
- The fixed sizes available in the menu can be changed with a resource
- editor without recompiling. Default sizes are font dependent.
-
- o A window menu item was added to allow the bottom window to be sent
- to the top even if it is competely hidden. Another item sends the
- top window to the bottom. The latter is somewhat slow due to
- shortcomings in GEM.
-
- o The main keyboard digit keys when used while the alt key is down
- will select that window number to be the top and keyboard input
- window. The first window is alt-1, the last is alt-7. Windows
- are numbered as gem numbers them. Alt-key bindings for lower
- case letters are scanned from the menu strings in the resource
- file. These bindings are indicated by the ^E (close box)
- character.
-
- o A window menu item was added to shrink the current window to an
- iconic size. The second-from-the-top non-iconic window becomes
- the current window. The fuller box is used to reverse the process.
-
- o An option is now available to cause new windows to be created
- without the sliders and arrows. The title bar (and close and
- fuller boxes) may also be eliminated by another option. Menu
- items have been added to support most of the functionality lost
- when the window controls are turned off.
-
- o Additional help information was added to the about dialog.
-
- o Startgem is now included in the distribution. This program, if
- placed in the auto folder, will attempt to start a:\bin\uw.prg
- automatically when the ST is booted up.
-
- o A variable called "locpath" contains the name of a directory to
- scan after the current directory when looking for configuration
- and font files. The string is 64 bytes long and defaults to
- c:\bin.
-
- o An RS232 configuration dialog has been added. There is no pro-
- vision for putting this information in the configuration file.
- Bug view: There is no auto-configuration. Feature view: Changes
- persist across executions.
-
- o One can now capture host output to a file on a per-window basis.
- Capture mode is terminated by setting an empty file name.
-
- o Added keyboard lock to file menu. This locks the keyboard and mouse
- until your password is reentered.
-
- o Added change working directory item to file menu. This is usefull
- for kermit and the exec command entry.
-
- o Added execute command entry. This allows uw to be suspended while
- another command is executed. Note that mwc startup for gem does not
- preserve the environment variables. The default command and
- parameters are part of the config file.
-
- o Add basic kermit functionality. Kermit can operate under the uw
- protocol in a window concurent with interactive terminal windows.
- Sending multiple files is not yet supported.
-
-
- Extensions to Adm31 emulation:
-
- o If the host sends a window the sequence ESC [18t, the window will
- respond with ESC [8;<rows>;<cols>t, where <rows> and <cols> specify
- the window's size in characters.
-
- o The insert line and delete line escape sequences (ESC E and ESC R,
- respectively) allow a repeat count (ie, ESC 5E inserts 5 lines).
-
- Bugs fixed:
-
- o Exiting in "fast" mode used to leave a window open. The
- system would crash on the next run unless you had returned
- to the desktop.
-
- o Actions on windows now check that there are windows to act upon.
-
-
- Known bugs:
-
- o Because of the extra memory used in the jump scrolling
- algorithm, the bottom row of pixels of an earlier line
- sometimes appears immediately below the title bar.
-
- o GEM doesn't let you completely eliminate the menu bar and
- increase your workspace.
-
- o Desk accessories sometimes leave damage on the screen.
-
- o GEM doesn't send "top" messages to the top window, so you
- can't use the left mouse button as a short hand to select
- the top window for input. Use the right button on the window
- title bar instead.
-
- o The rsconf() baud rates listed in the manual as 75 and 50 baud
- really result in system timer settings for 120 and 80 baud.
- The RS232 configuration dialog allows you to set these two baud
- rates, but decodes them as 300 or 200 baud, respectively.
-
- o The RS232 configuration code uses some trickery to determine the
- current port configuration. Some parts of this code may need to
- be turned off or adapted to run on other hardware or if system
- calls stop returning undocumented values.
