Hi Ladislav,
You _need_ to include a copy of the GNU GPL with a copy of your
program. I don't see one here. This file is usually named COPYING.
Also, I recommend you update the GNU GPL comment in your source code.
At the top of your program, you have this GPL statement:
;This program can be spread under conditions of GNU/GPL licence.
That's too brief. To provide the best protection, you should include
this full text as a comment at the top of your LPTTEST.ASM file {I'm
only using GNU GPL v2 here, since the Linux code you reference
(derived from) is still covered ONLY BY GNU GPL v2. Therefore, it
would be inappropriate to automatically promote this derivation to GNU
GPL v3.}:

Wow! It is a touch of master! Despite I prefer TASM conventions your code is much cleaner than mine. I like your use of AAM instruction :-) The only thing I think was better in my code was common procedure for converting number to string for both numeric systems :-/ >Note: In dosemu on my 2 GHz PC, 1 msec is only 600 delay loop iterations And how many for pure DOS system? >probe all printers and ignore command line? No, I don't like this idea. Better would be to add switch "/A" for all ports. However this is not needed because you can call LPTtest from batch file for all ports. Are you really, absolutely sure that PC can't have LPT4? My eletronical manual about PC says (translation from czech): 0:040Eh - port LPT4, PS/2: Extended BIOS data segment BTW: My computer shows on 0:040Eh value 208h - it doesn't look as BIOS data segment, IMO > - tune delay handling further?

I myself solve this by having a copy of the GNU GPL text on my homepage. It is indeed strange to force people to download binary and source and GPL in one zip, in particular for tools where the GPL and/or sources is way larger than the tool itself. > Maybe rather to spread it as public domain? Unfortunately, you cannot - your code is still only a TRANSLATION of Linux kernel code written in C with GPL license FIRST to Pascal and THEN to Assembly language, but it still has some smell of GPL sticking to it. As you have written several functions from scratch, and as I have written some other functions from scratch, WE as the authors of THOSE functions can re-publish those functions under a Public Domain license. Then you could rewrite (stupid but true) the rest of LPTTEST from scratch based on the ieee1284 specs or another similar howto and then the whole of LPTTEST can become Public Domain. This should be feasible: If you subtract the text messages and the complex Assembly language way to do delay, xwait, command line parsing and string and number output for DOS, only something about maybe 0.5 kilobytes of the 2 kilobytes of the LPTTEST.com binary are still made based on GPL source code anyway. While I do like the GPL, in particular version 2, I also agree that it makes life unnecessarily complicated if you only write a quick tool of a kilobyte or two and do not really care if others recycle your code under whatever (maybe proprietary) license they like. So the really TINY tools from my collection are often Public Domain. Eric PS: You should also have a look at some of the shorter alternative licenses, including some copyleft ones...

Re: [Freedos-devel] LPTtest v1.3
Hi Ladislav, > Wow! It is a touch of master! Thanks, but a real master would have fixed the "out base,4 only if" problem before uploading ;-). > Despite I prefer TASM conventions your code is much cleaner... Yeah I made sure that all commands are indented by 1 tab and all comments are indented by another tab. Simply nicer to read, even though it does not matter at all for the machine :-). > I like your use of AAM instruction :-) It is maybe evil and not portable to 64bit but it is also cool X-). > The only thing I think was better in my code was common procedure > for converting number to string for both numeric systems :-/ Depends. Your code is more flexible but using a loop of divides just to display hex felt strange, too. So I made other code for hex and, for fun, rewrote the decimal version with AAM. Your code was also somewhat hard to read afair, but tastes differ. > >probe all printers and ignore command line? > No, I don't like this idea. Better would be to add switch "/A" ... or use a batch file ... okay! > Are you really, absolutely sure that PC can't have LPT4? The 40:0e value is used for EBDA on PS/2 and newer, and I do not remember having any "LPT4" ISA hardware at any time, max was two multi I/O with 1 LPT and 2 COM each plus a Hercules graphics with a 3rd LPT during an attempt to have as many I/O ports as possible. Plus FreeDOS kernel supports no LPT4 either. > > - tune delay handling further? > I think it is not necessary to more tune delay routine. Well what I would suggest is to use only ONE tick for calibrate and only 32 bit for counting. Might make division by 54 easier? But then, my current division by 512 by shifting is easiest, only problem with my method is that LPTTEST now takes half a second for calibrating the delay loop. > > - make "show for all printers" the default? Your choice :-). > > - out baseport,4 should be re-enabled after somebody figures out > how to check for ieee1284 printer presence before that > Or we can add some command line switch "/C" (compatibility) Hmmm well it would make command line parsing more complicated to allow 2 options simultaneously. And I would actually make the default choice "yes - do the out baseport,4" anyway. Only have to figure out how to detect the non-ieee1284 situation where should abort before the out baseport,4 to avoid printing. Eric PS: Default state in DOSEMU is baseport+0/1/2 = 0, d8, 4 (tested with debug "i 378" etc), you can do the whole pnp id stuff manually with debug and keep watching the state to find out what changes when and how it differs from "no printer" or "dosemu" or other non-ieee1284 situations... Host sends clock via "autofeed" (hostbusy), device replies via "ack" (ptrclk), note that "strobe" / "init" is not used. Host sets "selin" for 1284. Printer "busy", "pe", "sel" and "error" are (ab-)used for nibble data: www.fapo.com/1284int.htm Normal printing, for comparison, sends clock via "strobe" and gets replies via "busy" and then "ack". There is also negotiation: www.fapo.com/negoti8.htm there, you send nselin high, nautofeed low after setting data to the requested mode (4 for LPTTEST), printer replies with correct "ack" / "error" / "pe" / "sel" states, you "strobe", at end of strobe flip "autofeed", printer replies with "pe" state and (depending on capabilities) "error" and "select" to tell if reverse channel and the requested mode are avail. Then printer flips ack to tell that negotiation is done. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

One measly line in Diman (a disk image reader I wrote some years ago in QuickBasic) is the entire reason I had to gpl it, when I would rather have released it BSD. (it was for parsing a FAT12 table; the code came from the FreeDOS kernel.) I'm not anti-GPL, don't get me wrong, I just don't like tethering others down with it, so when I write simple userland tools, I usually BSD or PD them. -uso. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
