Oh oh. I was mistaken. It was Dave Dunfield's MC323EXA.ZIP with the files ./DOSUTIL/REDIRECT.TXT ./DOSUTIL/RERROR.C ./DOSUTIL/ROUTPUT.C
RERROR handles stderr capture via DOS. ROUTPUT handles ALL text capture via BIOS. http://dunfield.classiccmp.org/dos/mc323exa.zip On Thu, Mar 23, 2023 at 5:04 PM Louis Santillan <lpsan...@gmail.com> wrote: > > I forget which one and which version, but it had the ability to > redirect the blacked out screen to a file.
