Re: QUARTERDECK QEMM products ... Good? or Garbage?

The memory management side of DOS became back in the day of DOS primetime, a matter of availability and obscurantism: Only a few options were locally known and available. You must consider that the internet was not as widespread and common as it is today. We had mostly Bulletin Board Systems (BBS) …

It is a pity, the project looked very good and promising. Probably the best modern looking GUI for DOS in the works. At least I managed to archive the latest releases before the site went down. Unfortunately the stored old website in archive.org did not back up them, so if the author sees no issue I …

Thank you very much. It works for me. Cool! That said if you would like to improve upon VGAONOFF I would dare suggest the following changes: 1. Make sure the binaries archive contained also the example BAT files (currently only available in the sources archive). Oops, I never looked in the .zip …

I guess that has something to do with STDERR. Some programs print standard messages to STDOUT and error messages to STDERR If you use redirection with "> NUL" you just redirect STDOUT. Don't use "> NULL" ! I don't know whether "CTTY NUL" redirects STDERR too. In Windows' Dosbox you can redirect …

Some nice suggestions in the last few posts! Also it was interesting to learn about the difference between redirection and CTTY in terms of stderr. I posted the tool I wrote on GitHub, vgaonoff-0.1.zip available from here includes both source and binary. I also included some example batch files …

One permanent version is HEX edit those unneeded messages out from your SYS and executable files. I usually strip all unneeded from my stuff for personal use, and then Apack Syspack Upx all those. Great for super boot floppies also. Yes, it should work on most cases, but many programs are either …

While, I was ready to give a go to this approach, I found a tiny program called PAGE that just switched between different pages (yes, they are four). DOS boots on PAGE 0 and before the offending program starts, I switched to PAGE 1 and after it was initialized, I cleared that screen and returned to …

Indeed, outputting to null should fix most of it. eg, LH Verboseprg.exe > null Perhaps, you missunderstood my request, I have already gone way past the regular OS route. Maybe hook the BIOS and DOS interrupts for the duration of autoexec.bat? You could pass through all functions unrelated to screen …

Help in fighting against startup messages in DOS programs

Hi, I was hoping some of you may drive me to the answer I am looking for: The thing is that in my AUTOEXEC.BAT, I start several programs. A few of them usually spit out some startup message to the CON. And a few are really writing quite a long string of text that clutters the screen. I have managed …
