- This is the history of PARCP development:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- 2.62 - 29.07.1997
- =================
- - PARCP clearly displays which configuration file is used now.
-
-
- 2.60 - 22.07.1997 - PARCP has become keyware, PARCP cable is available
- =================
- - PARCP now recognizes two new directives in the CFG file: Username and
- Keycode. You'll get the keycode when you register.
-
- - thanks to idea from Ivan Dimbleby I asked Titan Designs if they could
- make the PARCP cables for PARCP users. They agreed, so now you can order
- the PARCP cable at them, hopefully. Read the documentation for more
- informations.
-
- - Sorting has been rewritten to eat less memory. It may however still be
- too slow on 8 MHz machines - please check it out, I still can optimize it
- a bit
-
- - fixed priority bug - the $PARCPDIR had a higher priority than the -f
- command line option by a mistake. Now it is fixed, so you can really use
- the configuration file you point to with the -f option even when the
- PARCPDIR variable is set. This allows you to have one most used
- configuration which the PARCPDIR points to and one or more less
- frequently used config files which you can select by the option on the
- command line of PARCP.
-
- - some little fixes and enhancements (Client should get all error reports
- from Server now).
-
-
- 2.55beta - 09.07.1997 - I have reached *two* registered users. Wow! :-|
- =====================
- - Alt-Ctrl-Shift as the Interrupt Key works now in DOS version of PARCP,
- too. It was rather easy to add this, because the internals of TOS and DOS
- are *very* similar to each other (even the bit fields of special keys
- match in TOS and DOS! :-)
-
- - Dir listing has been modified (especially the format of date and time).
- The maximum length of filename in dir list is 32 characters now (is it
- enough?) All directories are listed together before files (handy! :-)
-
- - Sorting of dir listing!! I was planning to add it later to the fullscreen
- version of PARCP 3.0, but I have written it already. Seven different ways
- of sorting! (see the SORT command discussion).
-
- - sending of filenames with wildcards has been rewritten. You should notice
- that especially when sending files from top/root directory of large disk
- with deep directory tree (in previous versions of PARCP the routine for
- sending files searched through the whole directory tree even when it was
- unnecessary).
-
- - internal changes for better memory management (is it better, Koos?)
-
-
- 2.50 - 22.06.1997 - thanks for bugreport to Ivan Dimbleby
- =================
- - fixed stupid bug in DEL command (template matching didn't work)
-
- - DEL command enhanced - now it deletes files and directories recursively
- (if SUBD is ON, see documentation)
-
- - new command REN for renaming files (command set is complete now, I think)
-
- - SAVE command enhanced - now it can create missing cfg file, update all
- values in existing cfg file and even add new lines to existing cfg file -
- that's important for easy updating cfg files with new commands of still
- developed PARCP.
-
-
- 2.40 - 10.06.1997 - I really need more regular betatesters!
- =================
- - the most important news: I have found the reason of random unexpected
- crashes of Atari PARCP - the program stack was overflowing :-(
- C, the high-level language strikes back again.... Next time I'll start in
- pure assembler, I swear! :-)
- Anyway, the stack is increased to 16 kB, hopefully it will be enough.
-
- - fixed a problem of drag&drop directories - now you can put on the command
- line of PARCP not only files to be sent, but also directories or even
- whole drives! Yes, it's possible to say PARCP D:, which will copy all
- files from your D: drive to the Server! Isn't it just nice for CD-ROM
- burning?
-
- - a quick work-around of another possible bug in MiNTlibs (chdir()).
- It seems that I will have to update a quite few MiNTlibs calls soon.
- Maybe I'll become the MiNTlibs maintainer? :-)
-
- - fixed a stupid bug which was introduced yesterday in 2.30 release.
- Sending of multiple files by drag&drop works fine again.
-
-
- 2.30 - 09.06.1997 - PARCP is shareware and is supported by CyberSTrider
- =================
- - first of all: found and fixed bug in MiNTlibs! The CD-ROM related
- problems were caused by this bug (apology goes to author of MetaDOS).
- Dir should work fine in CD-ROM directories now.
-
- - a problem with long response time of slow CD-ROM drives and CD's with
- huge directories required to enlarge the standard 10 seconds timeout
- value. That's why you find new configuration command 'Timeout' which
- takes decimal number as the timeout value in seconds.
-
- - new Client command STAT for showing actual settings (since switches don't
- show all settings anymore).
-
- - new Client command SAVE for saving actual settings into configuration
- file. The SAVE command parses the configuration file and strips all
- commands - so don't be surprised. Maybe I'll fix that later.
-
- - during drag&drop existing files the 'Quit' possibility now works as
- expected.
-
- - two new AKA's were introduced: ls = DIR, lls = LDIR (specially for Koos
- Kuil :-) PARCP Client is fully compatible with usual FTP clients now.
-
- - minor fixes and code cleanups.
-
-
- 2.20 - 01.06.1997
- =================
- - Fast assembler routines for Atari have been optimized once more.
- I think I have reached the limits of hardware and the PARCP can't be
- made faster. I'll concentrate on IBM assembler routines in future
- PARCP releases.
-
- - introduced a workaround for annoying bug in MetaDOS - now I know finally
- why so many clean programs have problems with reading files on CD-ROMs!
-
- - Abort Key stops multiple files transfer now
-
- - new Client commands:
- mkdir = alias for MD
- bye = alias for QUIT
- LMD -> creates directory on Client (alias is lmkdir)
-
- - when asking for overwrite you can choose "Quit" from multiple files transfer
-
- - fixed silly bug with invisible characters (a bug in my working version
- of MiNTlibs... soon you will know what's going on here)
-
-
- 2.11beta - 26.05.1997
- =====================
- - fixed cosmetic bug in percentage displaying
-
- - greatly enhanced configuration file handling - PARCP can now create
- or update its configuration file correctly.
-
- - writting PARCP new documentation is in progress...
-
-
- 2.10beta - 06.05.1997
- =====================
-
- Bugfixes:
- ---------
- - better access rights to directories created on Linux/MiNT
-
- - a workaround for evil bug in TOS (statfs()) - no more
- "Please insert a X: diskette into drive A:" alerts
-
- Important changes:
- ------------------
- - PARCP.CFG - at last! Configuration file of PARCP with all switches and
- many new variables is available. Details will be discussed in documentation.
-
- - the environment variable "PARCPPAR" is obsolete now! Use the
- configuration file for setting up your favourite switches etc.
-
- - a new env.variable "PARCPDIR" is recognized. It should point to
- PARCP home directory (it's used for searching the PARCP.CFG)
-
- - command line parameters reduced to -s (PARCP Server) and -f filename
- where filename points to an alternate configuration file.
-
- Configuration file:
- -------------------
- It's a plain textfile, can be freely edited by hand. The configuration
- file is searched:
- 1) where -f command points to. If it's not a valid config file, then...
- 2) search for PARCP.CFG in actual directory, then...
- 3) in PARCP's home directory, and at last...
- 4) in $PARCPDIR directory
-
- New features:
- -------------
- - transfer in progress can be interrupted any time by pressing
- on Atari: Alt-LeftShift-Control
- on IBM: Ctrl-C
-
- - waiting PARCP Server can be aborted the same way as the file transfer
-
- - PARCP can keep time-stamp of copied file (KEEP switch)
-
- - better buffering of files - you can specify how big is file buffer
-
- - variable length of transfer block - use longer block for higher speed
-
- - better handshanking - just protocol revision is checked
- (PARCP v2.10 will be compatible with newer versions until a protocol
- change will occur)
-
- - debug version of PARCP can be compiled.
-
- - when HASH is OFF the progress is indicated by percentage of transferred
- file size
-
- - after drag & drop file on PARCP Client the can receive the file and
- quit (QuitAfterDrop = TRUE) or stay and wait for another connection.
-
-
- 2.04beta - 12.04.1997 - thanks to Koos Kuil for bugreports!
- =====================
- - fixed problem with transferring files 0 bytes long
-
- - fixed problem with displaying free space on a disk
-
- - new command 'F' is recognized in PARCPPAR environment variable.
- It enables the fast assembler routines on Atari PARCP.
-
- - added CWSDPMI.EXE which provides DPMI services for IBM PARCP.
- Please read enclosed CWSDPMI.DOC, thanks.
-
-
- 2.03beta - 31.03.1997
- =====================
- - FAST ASSEMBLER ROUTINES RE-IMPLEMENTED!! The transfer speed is back
- to 88 kB/s!! You can select between the original TOS routines and the new
- fast assembler ones on-the-fly by Client command "FAST". The fast routines
- are disabled by default for max. compatibility.
-
- - fixed litle problem with "Error reading the file"
-
- - fixed problem with drag&dropping directories
-
- - little cosmetic changes
-
-
- 2.02beta - 29.03.1997
- =====================
- - BUGFIX: drag&drop didn't work
-
- - sending of single files (filename without wildcards) is now faster
- because they aren't searched in directory but send immediately.
-
-
- 2.01beta - 28.03.1997
- =====================
- - long awaited feature: PARCP can now send or receive whole subdirectories!
- By default this is turned on, but it can be turned off by "d" in $PARCPPAR
- I've also found a bug in Linux's libc, will have to report it...
-
- - PARCP reports the length of transferred file in blocks (= in dots)
-
- - Client's switch commands (HASH,CASE,OVER,SUBD) without the ON or OFF
- parameter acts as a toggle switch.
-
- - removed two problems with timeouts while waiting for answer to
- "Overwrite?" question.
-
-
- 2.00beta - 25.03.1997
- =====================
- - PARCP has been completely rewritten and is now compiled by GNU C 2.7.2
-
- News: - PARCP uses new method of handshaking (end of "Timeouts" I believe)
-
- - PARCP supports multitasking operating systems
-
- - PARCP Server does not hog CPU while waiting for connection!
-
- - PARCP reads an environment variable PARCPPAR and uses its
- value for setting of different PARCP options
-
- - PARCP Client is much more comfortable
-
- - drag&drop of files onto PARCP Client is supported again!
-
- - .. and much more, I can't remember it all.
-
- - I have no time for updating docs so I am releasing PARCP `as is', mainly
- for betatesters.
-
-
- 1.00beta - 31.12.1996
- =====================
- - lowlevel assembler code on Atari has been optimized one more time. It
- saved another 80 CPU cycles in the inner loops. Receiving of two bytes
- should (in ideal case) take only 350 cycles - that makes the upper limit
- of transfer speed around fantastic 40 kB/s on standard 8 MHz ST!
-
- - dir listing buffer decreased to 4096 bytes
-
- - HASH mark changed to dot '.' (dot is nicer I think :)
-
- - documentation updated and whole package released.
-
-
- 0.78beta - 30.12.1996
- =====================
- - added new commands L/DEL: it, as the name says, deletes files.
-
- - eliminated possible problems with different sizes of library constants
- between Pure and Borland C (e.g. MAXPATH is 119 on Atari but 260 on PC)
-
- - dir list can now be cancelled by pressing 'q' in "more" prompt
-
- - many code clean ups
-
-
- 0.77beta - 28.12.1996
- =====================
- - removed about four errors from send_files(), now it really works
-
- - removed all waitings for a key - now it should be ready for batch
- processing
-
-
- 0.76beta - 27.12.1996
- =====================
- - added new commands PGLEN, GET:
-
- 'PGLEN' sets the number of lines on your screen. Default is 25, but e.g.
- I have 40 lines on screen. If you set 0 lines, dir listing will
- not be stopped.
-
- 'GET' transfers a file or files from server to client
-
- - some important code cleanups
-
- - eliminated possible problems with memory overflow in handshake()
-
-
- 0.75beta - 26.12.1996
- =====================
- - added new commands LQUIT, HASH:
-
- 'HASH' turnes on and off printing characters indicating transfer in
- progress
-
- 'LQUIT' is a very important command - it quits just the client while
- server keeps waiting for another session. This way you can start
- server on one machine automatically after boot up and connect
- from the other machine only sometimes when you need to copy a
- file.
-
- - memory buffers (55 kB) made statical (it may be better than allocating it
- dynamically every time - especially in multitasking environments)
-
-
- 0.74beta - 25.12.1996
- =====================
- - read() -> fread(), because read() on PC can read max 32 kB long block :-/
-
-
- 0.73beta - 24.12.1996
- =====================
- - DIR buffer made smaller (20 kB -> 10 kB) (Small memory model on PC)
-
- - little changes of source code with aim at PC compatibility
-
-
- 0.72beta - 23.12.1996
- =====================
- - user interface rewritten from scratch. PARCP now acts like ftp client and
- server. The idea was taken from Parallel communication routines written
- by Ian D. Gay (gay@sfu.ca).
-
- Implemented the following commands: L/PWD, L/CD, MD, PUT, L/DIR, HELP
- and QUIT.
-
- 'PWD' prints the current path (=drive and directory) on server
-
- 'CD' changes the current path on server
-
- 'DIR' lists files in current path on server
-
- 'L-functions' do the same but on client (i.e. local machine)
-
- 'MD' creates directory in current path on server
-
- 'PUT' sends a file or files from client to server
-
- 'HELP' shows short help message
-
- 'QUIT' ends both client and server
-
- - fopen() -> open(), fread() -> read() etc.
-
- - PC timeout increased to 1E7 empty loops
-
- - many small changes in the whole source code
-
-
- 0.71beta 24.11.1996
- ===================
- - ST part of lowlevel routines has been rewritten into assembler. It is now
- again much faster (on a plain ST the speed increase went from 16 up to 22
- kB/s).
-
- - true timer timeouts has been implemented in the ST version of PARCP. The
- timeout is now set to 3 seconds (I think it is enough even for reading
- from a floppy).
-
- - Since 0.70beta the transfer can be interrupted anytime by pressing Shift
- key on Atari computer or Return on PC (as you can see in the source code
- of lowlevel routines). I forgot to update docs, sorry.
-
- 21.12.1996
- - I thought I would be able to rewrite even the PC part of lowlevel
- routines into assembler, but I have no time for studying Intel assembler,
- so I am releasing this version for testing right now.
-
- - PAR_IN and PAR_OUT created.
-
- PAR_IN sets the parallel port into input state. If you use PARCP
- regularly and have the PARCP cable connected all the time, you should put
- PAR_IN into your AUTO folder (Atari) or AUTOEXEC.BAT (PC). It will
- minimize the danger of destroying your parallel ports.
-
- PAR_OUT resets the parallel port into output state which is the default
- after power on or reset of computer. If you want to print on printer
- after using PARCP, you have to run PAR_OUT first (or reset the computer).
-
- - documentation updated.
-
-
- 0.70beta 19.11.1996
- ===================
- - timeouts are hopefully away (I don't know why, but it doesn't matter :)
-
- - an old code for handshaking removed (it made more troubles than good
- things). Now it begins directly with sending or receiving, so please
- don't start Senders on both ends...
-
- - new speed records achieved: 56 kB/s on unidirectional port and 77 kB/s on
- bidirectional one (between my Falcon040 and IBM 6x86)
-
-
- 0.69beta (unreleased)
- =====================
- - tested communication between two PC's - proved that PARCP is totally
- flexible and works between any two supported computers (great!)
-
-
- 0.68beta (unreleased)
- =====================
- - still fighting.. also speeded up some little routines.
-
-
- 0.67beta (unreleased)
- =====================
- - fighting with strange problems - a lot of timeouts and other stuff.
- Can't find the reason...
-
-
- 0.66beta 14.11.1996
- ===================
- - initial handshaking has been improved a bit. PARCP now also does check
- of the PARCP version on both sides and refuses to work if the versions
- differ from each other.
-
- PC version only:
- - the command line parameter '-p' has been changed: now it is followed by
- the LPT port number (i.e. 2 for LPT2 or 3 for LPT3 - the default value
- is 1 => LPT1). That means you need not to search for the address of your
- parallel port anymore.
-
- - new command line parameter '-H' added: you have to use it if you have
- unidirectional parallel port only. You also have to use the HW adapter
- then. If you don't know what type of parallel port your machine has got,
- you can use my PARTEST.EXE.
-
- - PARTEST.EXE created. Before starting it please disconnect all peripherals
- and/or cables from your parallel port(s). After selecting LPT port it
- will tell you if you can use bidirectional feature of your port OR if
- you will have to build the HW adapter and always specify '-H' on command
- line of PARCP...
-
-
- 0.65beta (unreleased)
- =====================
- - timeouts added to the low-level functions. I have used very simple
- incrementing of a variable and counting to one million ;-) Hope it will be
- enough for every kind of machine..
- Transfer can also be interrupted by a keypress now.
-
-
- 0.64beta (unreleased)
- =====================
- PC version only:
- - now this is something we all have been waiting for: a support for
- bidirectional parallel ports of new PC motherboards!
- That simply means more speed and no HW adapter (with good PC motherboard,
- of course). This feature has been implemented thanks to important
- informations about PC hardware from Michal Kara.
-
- PARCP now can send or receive files with transfer rate about 72 kB/s on my
- system (Falcon040/40 and IBM6x86/60). That's quite good I think.
-
-
- 0.63beta (unreleased)
- =====================
- - introduced new, MUCH FASTER method of handshaking - the result is
- dramatical speed improvement (about 50% faster than 0.62beta!!)
- Thanks for the idea to Michal Kara.
-
-
- 0.62beta 23.10.96
- =================
- ~ compiled on a friend's PC (thanks to Milos Matus)
- - added option for selecting parallel port address (for PC version only)
- - ST version compiled with ARGV startup code - now you can pass much more
- filenames on the command line than before (the 126 chars limit is removed)
-
-
- 0.6beta 20.10.96
- ================
- ~ released at the Freecon '96 (Atari show in Pilsen)
- * a bug found: receiving more than one file at session didn't work
- - added check for passed filename (if it exists)
- * corrected bug in CABLES.TXT (the 13th pin of PC connector was wired wrongly)
-
-
- 0.5beta 16.10.1996
- ==================
- ~ the first public release (for friends only :)
-
- 0.3beta 20.8.1996
- ==================
- ~ I demonstrated the first working version of PARCP at Narsil Party 1996 in
- Trpisov.
-
- 0.1alpha 26.7.1996
- ==================
- This is the first saved PureC source code of PARCP. It already managed to
- drive both ST and PC parallel ports and to read and write data to it.
-
- First thoughts about PARallel CoPy came to my head in June 1996. I hated
- the bugs in ST-Trans and didn't like the half-way interface of HDD-Daemon
- 2.0. That's why I started working on PARCP...
-
