VDos 2021.05.01 Freezes

[panoscy]

Hi Guys.

I'm trying to run my old DOS software, configuration works, but when the DOS software starts it freezes. It stays on the initial screen and I cannot type anything. The inly way to exit VDos is with task manager - end process tree.
My OS is Win10 Pro x64. Info: other DOS programs are working, so I believe it is some compatibility issue and/or advance settings that must be done.
Any help would be greatly appreciated. Thanking you all in advance.

Most likely that DOS program will use INT 9 to communicate with the keyboard. INT 9 however isn’t emulated by vDos, so the program will wait forever.

To verify, you can start vDos with the log option (….vDos.exe /log). If the generated vDos.log indeed shows the INT 9 interrupt vector being replaced, it will end for vDos.

Hi. Thanks for the fast reply. Here is the log file, as I do not understand: vDos.log (415 B) Int9 is mentioned in there, so does that mean this software is not compatible? One other thing I noticed is that the cursor is also frozen. The initial screen is very basic, the user just has to enter todays date and press enter. Normally the cursor is flashing. In VDos the cursor is static. Thanks.

SI.COM indeed replaces Int 9, so it won’t work in vDos. You could try DOSBox instead.

I hate blinking things, so the cursor is static.

Thanks and sorry for the blinking...
Excellent work you've done here.

Update: DosBox is working!
Thanks!!!
