XX
XXRelease Notes:
XX--------------
XXv2.3 861101 DBW - minor bug fixes:
XX
XX - added p_wbcolors to allow workbench colors on custom screen
XX (In the init file you can specify WBCOLORS to be NO (use color
XX definitions in INIT FILE or VT100.H) or YES (use WORKBENCH
XX colors for everything)).
XX - "$" now sends a kermit-bye (like it says in VT100.DOC).
XX - made window/screen heights more reasonable
XX - Added ANSI insert line and delete line (<csi><num>L and
XX <csi><num>M) to speed up various editors (like emacs).
XX NOTE: This is NOT a VT100 sequence (new extension).
XX - ctrl-space now also sends a null (along with ^@ and ^`)
XX - RAWKEY fixed in WINDOW.C
XX - p_wrap fixed in WINDOW.C
XX - removed WRDMAX from VT100.H
XX - fixed exit with no params in SCRIPT.C
XX - fixed parity comparisons in KERMIT.C
XX - init file [n+1] changed to [nplus1] to make Lattice happy.
XX - cursoron(), cursoroff() changed to one routine cursorflip().
XX - long lines shortened to less than 80 characters (for gateways).
XX - blanks following exit (or comments) now work in scripts.
XX
XXv2.2 861012 DBW - more of the same:
XX
XX - The INIT file "exit" command can now take an optional argument
XX which is the name of a script to execute after initialization
XX is complete.
XX
XX - The SCRIPT command "exit" takes an optional paramater which may
XX be either the pathname of the next script to execute or the
XX string "VT100" (which causes the emulator to exit completely).
XX
XX - Hangup menu item now works.
XX
XX - Autowrap can now be set from VT100.H, VT100.INIT and the standard
XX escape sequence (<ESC>[?7h - set, <ESC>[?7l - reset)
XX
XX - Control-G is now handled with an audible beep (volume set with the
XX VOLUME parameter in VT100.H and VT100.INIT). If the volume is set
XX to 0, a visual beep (DisplayBeep) will be used instead.
XX
XX - Script now used "^chr" to send control characters instead of
XX "|" (which was screwing up U**X users). See VT100.DOC for details.
XX
XX - The graphics "box" character (a) was added so bar charts now work
XX in line drawing mode (e.g., monitor system on VMS).
XX
XX - Control-@ and Control-` now send the NULL character
XX
XX - Alternate color for BOLD has been re-instated by popular demand
XX (instead of using SetSoftStyle) when there is more than 1 bit-
XX plane. With one bit-plane, SetSoftStyle is used.
XX
XX - Menus have been cleaned up.
XX
XX - Lattice compilation cleaned up.
XX
XX - No more wordsize parameter since PARITY takes care of all cases
XX (NONE=8bit, MARK, SPACE, EVEN ODD).
XX
XX - Any function key definition that begins with a KEYSCRIPT
XX introducer will invoke a script from the function key: e.g.,
XX "~df1:foo/script.txt" (if KEYSCRIPT = 0x7E = "~")
XX
XX - Double shift keys are now handled correctly.
XX
XX - Version has been added to the title bar (for bug reports).
XX
XXv2.1 860915 DBW - new features / bug fixes
XX
XX - Now identifies as a VT100 (including the response to <esc>Z)
XX - Cursor color now gets read in as hex (instead of decimal)
XX - REPORTMOUSE taken out of definitions (not needed)
XX - XON/XOFF now being handled by the device driver instead of me
XX - Literal escape characters have been replaced with \033
XX - At init time the user can now specify the input BUFFER size
XX (typically between 512 and 2048 bytes) depending on baud rate
XX - Script files are now case insensitive for commands
XX - XMODEM now turns off the driver XON/XOFF during transfers
XX - Graphic rendition now done by the OS instead of me.
XX - Initialization files are now searched for in S: instead of C:
XX - Forward GOTO bug fixed in the script package.
XX - Keypad can now be used in both numeric and application mode
XX - General purpose cleanup() routine added for all exits.
XX - Utility menu added (sendbreak, hangup, change directory).
XX NOTE: hangup is not implemented yet.
XX - Full wild card support in file transfers (see vt100.doc).
XX - Kermit cleaned up with better filename handling (from host).
XX - Script now has CD (changed directory) and SB (send break) commands
XX - Added Parity and Wordsize choices in VT100.H, VT100.INIT, menu
XX and scripts. (Generates parity from a table).
XX - Added 8th bit quoting in KERMIT when using 7 bit words (ODD or
XX EVEN parity).
XX - Break time can be set from VT100.H, VT100.INIT or a script file.
XX - Transfer mode (image or CRLF) can now be set from a script file.
XX - Control characters in escape sequences now act like a true VT100.
XX - F10 now works from init files.
XX - Right (or Left) AMIGA with period (".") sends a BREAK to the host
XX from the keyboard.
XX - XMODEM status kept down to one line for a file transfer.
XX
XXv2.0 860823 DBW - Major rewrite:
XX
XX - Emulator now compiles under either MANX or LATTICE by defining
XX the appropriate compiler type in VT100.H.
XX - Sped up code to an effective baud rate of (about) 8k. This means
XX that clear text at 4800 baud should be no problem.
XX - Added XON/XOFF generation so that characters should not get lost
XX any more at 9600 baud (when receiving clear text).
XX - Got rid of all command line switches and environment variables.
XX Instead upon invocation the program searches first for any file
XX named on the command line, then looks for VT100.INIT in the
XX current directory and finally searches for C:VT100.INIT.
XX All parameters can be set in the init file, and a sample VT100.INIT
XX is provided in VT100.DOC that shows all possible options.
XX - All parameters that are set by VT100.INIT are defined in VT100.H
XX (variables starting with "p_"). This allows you to compile your
XX own defaults into the code.
XX - You can now set the number of lines (for all you EMACS freaks :-).
XX On an interlaced screen this gives you upto a 48 line terminal.
XX - WORKBENCH colors are NEVER touched.
XX - In an attempt to keep the size down, the color palette menu item
XX has been removed (current). Code is about 36K in size with a
XX run time image (using workbench screen) of about 88k.
XX - Many bugs fixed including reverse scrolling with descenders,
XX reverse video at end of line, clearing with scrolling regions,
XX ... and 20 or more others.
XX - File capture now no longer sends the filename to the host.
XX - BOLD (<esc>[1m) has now been added by using an additional color
XX when you specify a depth of 2 (instead of 1) bitplane.
XX - UNDERLINE (<esc>[4m) has now been added.
XX - The handling of remote (host) escape sequences has been completly
XX re-written (thanks to Dawn Banks for all the work).
XX - Function keys (and shifted function keys) can now be bound to
XX arbitrary strings (Jim Ravan gets his macros). See VT100.DOC
XX for details.
XX - Cursor has no been reduced to the size of a normal character for
XX easier readability.
XX - XMODEM has been improved (by Steve Drew) to use a timer device
XX (for timeouts) and to abort immediately if the user types <ESC>.
XX - KERMIT has been completely re-written and appears to work fine,
XX thanks to the efforts of Steve Drew.
XX - New menu item allows script file support. Module written by
XX Steve Drew. See VT100.DOC for details.
XX
XXKnown problems:
XX---------------
XX
XX - There have been some reports of the BELL (ctrl-g) not working
XX under Lattice. This is under investigation.
XX
XXSuggestions not implemented:
XX----------------------------
XX
XX - "ASCII capture uses synchronous I/O so capture of game playing
XX is jerky"
XX
XX This change MAY be made if someone else wants to write the code.
XX
XX - "Beep should be in stereo"
XX
XX I am trying to use as FEW system resources as possible, therefore
XX beep only ties up 1 of the 4 possible channels.
XX
XXInstallation:

XX thanks to all!
XX
XXProgram startup:
XX----------------
XX 1> vt100 [initfile]
XX
XX - At startup, the program will search for an initialization
XX file to execute. It will first look for the specified
XX "initfile", then VT100.INIT (in the current directory)
XX and finally S:VT100.INIT. The format for the init file
XX is described later in this document.
XX
XX - The init file controls the setting of initial defaults
XX and screen and macro definitions.
XX
XX - If none of the files (listed above) are found, the
XX built-in defaults (defined in VT100.H as variables,
XX beginning with "p_") are used.
XX
XX - All commands are either menu or script based. Scripts
XX are described below.
XX
XXMenus:
XX------
XXFile - file transfers
XX Ascii Capture - Begin/end a script of the current session
XX Ascii Send - Type a file to the host
XX Xmodem Receive - Receive a file using XMODEM protocol
XX Xmodem Send - Send a file using XMODEM protocol
XX Kermit Get - Receive files from a host KERMIT SERVER
XX Kermit Receive - Receive files from a host KERMIT
XX Kermit Send - Send files to a host KERMIT [SERVER]
XX Kermit Bye - Terminate a host KERMIT SERVER
XXComm Setup - Setup communications
XX Baud Rate - Set the terminal baud rate
XX 300, 1200, 2400,
XX 4800, 9600
XX Parity

XX EVEN, ODD - Type of parity
XX Xfer Mode
XX image - Send files verbatim (for UNIX hosts or
XX binary files)
XX CR LF - Send CR LF as line terminator and strip
XX CR on received files (VMS text).
XXScript - Script commands
XX Execute file - Start up an asynchronous script file
XX Abort Execution - Terminate a script file
XXUtility - Utility commands

XX - == , 2 keys up to get a VT100)
XX HELP == - (only free key around)
XX f1-f4 == PF1-PF4 (or any rebinding you do)
XX arrows == arrows
XX
XXNote: Right (or Left) AMIGA key in conjunction with a period (".")
XX will send a break to the host.
XX
XX CTRL in conjunction with either an at-sign ("@") or a backquote ("`")
XX will send a NULL to the host.
XX
XXInitialization file example:
XX----------------------------
XXHere is a (hopefully) self-explanatory VT100.INIT file with all
XXoptions used:
XX
XX#####################################################################
XX#
XX# VT100 sample initialization file
XX# v2.3 861101 DBW - Dave Wecker standard defaults
XX#
XX# Hash mark at the beginning of a line denotes a comment.
XX# White space (space(s) or tab(s)) delimit fields.
XX# Case ignored except for function key bindings.
XX#
XX# All items in this file overide variables of the same name in VT100.H
XX# (all variables in vt100.h have a "p_" prepended to them)
XX#
XX#####################################################################
XX#
XXBAUD 2400 # Anything after required fields is ignored
XXSCREEN CUSTOM # may be CUSTOM or WORKBENCH
XXINTERLACE ON # ON for CUSTOM or interlaced workbench
XXDEPTH 1 # number of bit planes to use (1 or 2)
XXWBCOLORS YES # ignore custom colors and use defaults
XXFOREGROUND 950 # Colors are only used on the custom screen
XXBACKGROUND 000 # Colors are in hex RGB from 000 to FFF
XXBOLD a00 # Color for bold highlighting (in custom)
XXCURSOR 00a # Color for cursor (in custom screen)
XXLINES 48 # normal <= 24 interlaced <= 48
XXMODE CRLF # IMAGE or CRLF (for KERMIT transfers)
XXBUFFER 512 # 512 <= Input buffer size <= 2048
XXPARITY NONE # NONE (= 8 bit), MARK, SPACE, ODD or EVEN
XXBREAK 750000 # Length for break key in microseconds
XXVOLUME 64 # Beep Volume (0 = Visual Beep)
XXWRAP OFF # Auto wrap ON or OFF
XXKEYSCRIPT 7E # Hex value for script introducer
XX#
XX# Function bindings (strings to type when any of F1 - F10 are pressed)
XX# f<num> = function key
XX# F<num> = shifted function key
XX#
XX# The string specified must be delimited and uses one special char:
XX# ^ = control next character
XX# ^^ = up arrow
XX#
XX# Sample control characters:
XX# ^[ = escape ^M = carriage return
XX# ^J = line feed ^L = form feed
XX#
XX# If the first character of the string is a script introducer
XX# (KEYSCRIPT) then the string is interpreted as a script filename
XX# to be executed when the key is pressed.
XX#
XX# Examples of bindings:
XX#
XXf1 "^[OP" # f1-f4 = PF1 - PF4 on a VT100
XXf2 "^[OQ"
XXf3 "^[OR"
XXf4 "^[OS"
XX#
XX# f5,6,7 = scripts to execute (assuming that KEYSCRIPT = '~' = 0x7E)
XX#
XXf5 "~df1:vt100_source/dialwork.script"
XXf6 "~df1:vt100_source/sendvt100.script"
XXf7 "~df1:vt100_source/getpics.script"
XX#
XXf8 "MAIL^M" # Reads my mail (note embedded <CR>)
XXf9 "NOTE^M" # Reads conferences
XXF1 "$2400!" # dials the phone to work
XXF2 "$bbs1!" # dials the phone to billboard 1
XXF3 "$bbs2!" # dials the phone to billboard 2
XXF4 "$bbs3!" # dials the phone to billboard 3
XX#
XX# all done with init, now execute script as startup sequence
XX#
XXexit df1:vt100_source/dialwork.script
XX
XXMulti file Xfers:
XX-----------------
XXThe VT100 emulator now supports multiple file transfers. This is
XXspecified by using a comma (",") between file names when using XMODEM
XXor KERMIT. (NOTE: host XMODEM's normally CANNOT support multiple file
XXtransfers).
XX
XXWhen specifying a file name to recieve by default the directory path
XXis stripped of the filename when sent to the host but is kept for the
XXlocal file spec. eg:
XX
XX receive file: ram:file.txt,df1:newfile.bin,$
XX
XXwill ask the server for file.txt and put it in ram:, and get
XXnewfile.bin and put it on df1: (see explanation of "$" below). If you
XXdo a single file transfer you will get another prompt for the remote
XXname e.g.:
XX
XX receive file: ram:file.txt
XX remote file name[file.txt] userdisk1:wantfile.txt
XX
XXThe same rules apply to sending multiple files therefore if you are
XXdoing multi file transfers make sure the host server is connected to
XXthe desired directory.
XX
XXIn addition KERMIT now supports wildcards (* = any number of
XXcharacters, ? = any single character). Examples:
XX
XX send: *.c,*.h,*.doc
XX get: *.c,*.h,$
XX
XXKERMIT receive is now smart enough to use the host filename so no
XXfilename needs to be specified on the AMIGA's side.
XX
XXScript file operation:
XX----------------------
XXThe script file can be invoked by selecting 'execute file' from the
XXscript menu. At any time you can abort the script file by selecting
XX'Abort Execution'.
XX
XXDuring the time script file is running the terminal emulation is still
XXactive and you may type simulataneous to the script file. This may be
XXdesired if your script file is WAITing for a string or is DELAYing for
XXa period of time etc.
XX
XXScript file Commands (case insensitive):
XX------------------------------------------------------------
XX# Commented line
XX Format:
XX # comment may not be on same line as a command.
XX Example:
XX # this is a comment
XX------------------------------------------------------------
XXASCII_SEND Send an ascii file to the host.
XX Format:
XX (same format as CAPTURE)
XX------------------------------------------------------------
XXBAUD Set baud rate
XX Format:
XX BAUD rate Sets the baud rate for send/receive
XX Example:
XX BAUD 2400 Sets the baud rate at 2400 baud
XX------------------------------------------------------------
XXBT Set the break time (for an SB command)
XX Format:
XX BT value Value is in micro-seconds
XX Example:
XX BT 750000
XX------------------------------------------------------------
XXCAPTURE To start/stop ascii file capture.
XX Format:
XX CAPTURE file Start ascii capturing
XX CAPTURE End ascii capturing
XX Example:
XX CAPTURE foo.bar Starts capture of file foo.bar
XX CAPTURE Ends ascii capture of file foo.bar
XX------------------------------------------------------------
XXCD To change the local directory
XX Format:
XX CD newdir set a new directory for file transfers
XX Example:
XX CD DF1:foo/bar set the directory as specified
XX------------------------------------------------------------
XXDELAY Suspends script file for a specified time
XX Format:
XX DELAY n Suspends execution for n seconds
XX Example:
XX DELAY 2 Suspends for 2 seconds
XX------------------------------------------------------------
XXEXIT Ends execution of the current script file.
XX Format:
XX EXIT Exit the current script
XX EXIT VT100 Exit vt100 program
XX EXIT newscript Exit this script and start up newscript
XX Example:
XX EXIT DF1:FOO.BAR Exit the current script and start FOO.BAR
XX------------------------------------------------------------
XXGOTO Jumps to a different part of the script file.
XX Format:
XX GOTO label Jumps to a line beginning with label:
XX Jumps may be forward or backward.
XX Example:
XX FOO: Sets up a label
XX GOTO FOO Jumps to FOO
XX------------------------------------------------------------
XXKB Send a BYE packet to a host KERMIT server (shut down server).
XX Format:
XX KB
XX------------------------------------------------------------
XXKG Gets files from host. (which is running as a server).
XX Format:
XX (same format as KS)
XX------------------------------------------------------------
XXKR Receives a file from kermit host (not running as server)
XX Format:
XX (same format as KS)
XX------------------------------------------------------------
XXKS Sends files via kermit to the host.
XX Format:
XX KS file Send one file
XX KS file1,file2,... Send multiple files
XX KS file1,file2,...,$ Send multiple files and shut down server
XX Example:
XX KS foo.bar sends foo.bar (note no quoting is used)
XX KS foo1,foo2,foo3 sends three files
XX KS foo1,foo2,foo3,$ sends three files and shuts down server
XX------------------------------------------------------------
XXON Peforms a command every time a string is received
XX Format:
XX ON "string" cmd Execute cmd when string is received.
XX Only one ON string may be installed at a
XX time.
XX
XX If cmd is a GOTO and we were previously
XX WAITing for a string the WAIT is aborted and
XX execution resumes at the new label.
XX
XX If cmd is not SEND and we were previously
XX DELAYing, then the DELAY is aborted and the
XX cmd is executed, followed by the next command
XX after the DELAY.
XX
XX If cmd is a SEND and we were previously
XX DELAYing, then the DELAY is continued.
