I didn’t think that, even to the contrarily: DOS printing to modern printers is more complex (That involves more than…). Sure, nothing would prevent DOSBox to do that, it’s just also more than a mere ‘like Word and other applications do’.

DOSPRN is a Windows program, it can’t be started from inside DOSBox (MegaBuild 6). You would have to setup your program to print to a file, then let DOSPRN monitor the print files. You could have a go with vDos, eventually you can still use DOSPRN for printing if vDos own print processor isn’t …

Don’t think DOS users will be satisfied by a DOSBox mod ‘supporting printing’. That involves more than just sending ASCII data to a parallel or serial port. Most modern PC’s don’t have such ports, while printers often don’t support ASCII data streams.

vDos is meant to run serious DOS applications - still in use - not to play with. So vDosPlus will be the way to go.

If the key repeat (delay) works fine in Windows programs, you could give vDos (https://www.vdos.info) a try. It conforms (more) to Windows keyboard handling, and will also be more pleasant to the eyes.

You didn’t clarify why your DOS program needs to directly access port 0278h. If it’s non-gaming, you could try vDos. Mind the required settings in config.txt, something like lpt1 = “lpt1”:. While such hardware port access wasn’t noticed before… Jos

SHARE.EXE actually doesn’t work with DOSBox: File operations are cached, while data has to be actual (in memory match that on disk) for record locking to function reliable.

DOSBox caches file operations, its internals don’t have to match the actual data. If you have another program, DOS or Windows, accessing the same data, you have to expect file corruption. Especially database programs are vulnerable. No DOSBox mod was proven to fix this due to that caching of file …

A WordStar-style editor in DOSBox is indeed ‘not the designed-for use’. You could have a look at vDos (www.vdos.info). It should be better in handling non-gaming programs.

No LFN in MS-DOS 5.x (DOSBox), no games or applications depending on LFN. You could instead start Windows CMD and useful quickly CD all day long.

With "mount C C:\NAMEOFPROGRAM\SOMEOTHERNAME", the DOSBox C drive has no NAMEOFPROGRAM directory. So copy C:\NAMEOFPROGRAM to C:\DOSBox. Then MOUNT C C:\DOSBox, so there’s actually a C:\NAMEOFPROGRAM\SOMEOTHERNAME in DOSBox.

Without knowing what that DOS program would be, nor what it is supposed to do after a menu selection, there’s no real answer. My best guess would be that a (sub)program is to be started. Though not found since it tries to start for instance c:\dosprog\proga.exe while there’s no c:\dosprog in DOSBox. …

The program will try to lock some part of a file. DOSBox doesn’t support record locking, and returns an error condition. The program then just assumes someone else already locked what it tries to get a lock on. You could try vDos (www.vdos.info), that supports record locking and concurrent file …

There's no such thing as a 'non-DOS file', just a file. And it's a matter of fact that modern computers are going to be using LFNs no matter what and that DOS (under DOSBox or otherwise) must coexist with that. I know LFN support isn't that critical; the only reason I talk about it is that there is …

Any DOS program is by default limited to 20 open file handles, the size of the file table in the PSP. If a program needs more, it has to call Int 21-67h to extend that table (and move it out of the PSP). If the number of DOS global file handles (files=…) wouldn’t be sufficient to accommodate that, …
