- This is the history of PARCP development:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- 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 :)
