I just made a quick check under DOSBox. Copied REVERSI from ILPer to the internal drive and got an error. The file of the internal drive was corrupted and at a restart the Emu71/DOS memory was cleared.

I made the same test with Emu71/DOS but this time with VirtualBox and FreeDOS and everthing worked fine. Same virtual image, but now under VMware 12, also fine.

Final test with DOSBox and a shortcut in ILPilsim: Out Port = In Port, so no external device. The transfer from REVERSI memory to REVERSI:2 disk failed also.

Somewhere the serial implementation of DOSBox has a serious problem.

Thanks for your checking and confirmation Christoph. Do you think there is any point to do more testing to try to find an exact failure mode or sequence, or is it pointless since even if found, it would not appear DOSBox would be fixed, as the latest version is from 2010?

I guess it's time to install VirtualBox again. Does VB use the same named pipe to access the virtual serial port? If you don't have links handy for the configuration I can look around for details, I've found it fairly well documented in the past.

Thanks again.

Recently the DOSBox team released the new version 0.74-2. After first tests with this version and ILPilsim v1.01 it seem that the problem has gone.

You may give DOSBox a new try and tell us your experiences with 0.74-2.

For those who don't know the DOSBox settings any more (had been removed in last ILPilsim manual):
serial1=nullmodem server:localhost port:59999 transparent:1 txdelay:0 rxdelay:0
