People running DOS door games under DOSBox. Many old DOS doors support multiple concurrent users using semaphore files and/or sharing/locking. While many of the old games can be used under modern Windows OSs, or under Linux/DosEmu, ones that don't support FOSSIL, or systems running a different OS …

Well, a quick dig through the source code shows no sign of share modes in interrupt 0x21/AH=0x3D (Open) and no 0x21/AH=5c code at all... so SHARE is obviously not functional. Share open modes can easily be implemented using lock files, but the range locking is quite a bit trickier... I suppose the " …

I have to use it because my Win32 box is headless... no keyboard or mouse (it's the mouse that gets you).

Wonderfull! Works great on my test box. I updated the instructions at http://dosbox.bbsdev.net/ to point to your site... would you prefer if I mirrored the files on my system and had them downlod from there instead?

Not unless you run a BBS, no... the quickest way would be to grab GameSrv from http://www.randm.ca/files/gamesrv.rar grab a door game, set it up for direct serial... fiddle with the setup as per instructions on http://dosbox.bbsdev.net/ etc not really "simple". If you wouldn't mind supplying a …

As "The Serial Guy" any chance of you mergeing patch 1363544 (Support socket inheritance) into your stuff and getting it pushed into CVS? I've got people agitating for a build using it. I'm a FreeBSD guy, so I don't feel like jumping through all the hoops on my single headless Win2K box to get these …
