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.
