Yes, so are you mad I didn't preface that with "You could install LAN Manager Client for DOS, Novell network support and use DOSNP.EXE or run inside a VDM using named pipes" ? First paragraph of https://helparchive.huntertur.net/document/61238 : "The Communications Server MS-DOS and OS/2 clients use named pipe connections to communicate with OS/2-based Communications Server computers." A problem someone was having with named pipes in MS-DOS with DOS LAN Manager https://library.thedatadungeon.com/msdn-1992-09/kbase/html/kbas5c4h.htm And a problem using named pipes with Windows 3.11 (interesting symptom for a DOS machine to have) https://jeffpar.github.io/kbarchive/kb/119/Q119106/ And the manual for MS SQL states the DOS client support uses named pipes too, using a TSR like the Novell one does. I can't find the link anymore but I'm guessing that's why they added those functions to the NTVDM in the first place (they mentioned it was for DOS Point-of-Sale software). ... and in any case, you said "DOS programs" don't support named pipes. If you want to say that it isn't technically a DOS program if it uses interrupts that aren't supported on a plain install of MS-DOS 4, well, sure: DM> DM> DM> Nope, those pipe functions are *not* present in the supported functions DM> of MS-DOS v4. MS-DOS 4 also didn't come with DPMI support. It didn't exist yet.. are those DOS programs or nah? :) --- Mystic BBS v1.12 A47 2021/12/25 (Windows/32) * Origin: cold fusion - cfbbs.net - grand rapids, mi (21:1/616) .
