Hi,
I would like to use an old instrument which has DOS control software and connects through serial port. I could start the software and it could communicate with the instrument through the serial port, but it throws an error and can not run its internal applications. I tried a DOSBox variant DOSBox-X, which can run the software, but it is way too slow, one measure takes 26-38s (changing the cpu settings did not change the measure time). I better would use DOSBox, not an alternative variant.
It seems that every time the software try to list the folder, it runs to this error and don't find the internal applications. I tried to mount the drive with -freespace option (at the select application screen the software writes out the free space left), that did not help at all.
I would like to know how could I find the root cause of the problem and solve it?

System:
Dell Latitude E5430, Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz, 16GB DDR3 RAM, Windows 10 professional x64, MOXA UPort 1110 USB-Serial converter, DOSBox 0.74-3

I compare the slowness to an Intel Celeron @300MHz with 196MB of SDRAM, where the screen becomes instant and one measure takes 6-8s.

There's a good chance that booting real DOS from a HDD image inside DOSBox will fix whatever problems your app has with file/disk access. The trade-off with this method is that you can't access the files in the DOS environment from Windows as easily.

I don't know what would help the performance of your measurements though.

DOSBox IS NOT SUITED TO RUN YOUR NON-GAMING DOS APPLICATION

Consider trying vDos, vDosPlus, etc.

DOSBox is not intended to be used for anything other than games, and its developers and support team on VOGONS.org (the official support forum for DOSBox) will not support your use of it for a non-gaming application - but other forks of DOSBox might.
