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.
