Hi Eric, > > Do you mean, authors making their programs FDAPM aware?

These are free for download: Desi-III CAD http://users.telenet.be/desi-iii/index.html ShowJPG image viewer http://www.pictview.com/ PictView image viewer (same as above) LXPic image viewer http://hplx.pgdn.de/ > In what way are they CPU-hot? FDAPM reports 0% idle time, and CPU is indeed very hot to the touch. > And in what way does DPAKBD treat them differently? I load DPAKBD before running any of these programs, and (try to) unload it afterwards -- by means of a batch file, of course. In other words, I only keep it loaded when a non-FDAPM-aware program is running. > Are there also side effects of using DPAKBD? Does it maybe slow > down the programs that it makes CPU-cool?

The only case I remember in which there is a noticeable (and somewhat annoying) slowing down of mouse and keyboard action is Dillo. Interestingly, in the DataPerfect database, even reports -- a CPU-intensive activity -- run quite fast. I have not taken any actual measurements, but my guess is that they lose perhaps 30% of their speed, which is not so bad. However, if DPAKBD is not properly unloaded afterwards, other programs can effectively become very slow. > Can you give some more explanations about what DPAKBD is and > does, which license it has, which configuration options...? Let me tell about configurations first. The most important switches are (I think) /D and /T -- see explanation below. The trick of using DPAKBD is doing a lot of experimentation with these two values. Fortunately, many programs will work well (in my computer) with /D3 /T100, so I adopted these as default values. But some programs such as Arachne, Dillo and HighView (my favorite file viewer) have required hours of trial and error before I could get something acceptable. The /C switch did not work for me. Below is the full text of the DPAKBD.TXT file. As you see, nothing is said about license or registration. I looked for more information on the internet (because I like to pay for the license whenever requested) but could not find anything at all. ----begin----------- Citrix Australia Pty Ltd DPAKBD is a TSR that attempts to put errant DOS application that poll the keyboard incessantly to sleep thus enabling the CPU to service the rest of its process queue. It must be executed in the same NTVDM as the application but before the application is executed. Usage: DPAKBD /Dnn /Tnn /I /Cnn where nn specifies a value /D specifies the number of time slices to give up /T specifies a threshold number of polls that can be made in 1 clock tick (1/18.2 secs) before time slice sharing kicks in. /I monitors file locks /C uses a more aggressive method that ignores the /D and /T switch. Note: The /C switch will only work if the following is done 1. start the PIF editor (pifedit) and in the Program Filename edit box enter "command.com" 2. select the "Advanced Button" and uncheck the Detect Idle Time check box. 3. Fill in any other parameters like working directory etc 4. Save this PIF file and then run it. 5. type "dpakbd /Cnn", where nn is a counter value, the higher this value the more the application is put to sleep. The default value is 3. 6. Execute your DOS application. ----end------------- And in a separate file there was this single sentence: "This file was downloaded is from http://thethin.net and is posted with permission from the author." > How about elinks, lynx, w3m, Arachne, Dillo? Yes, Lynx is also FDAPM-aware. Arachne and Dillo are not. I have never used elinks or w3m.
