If not, were there any MODE commands for the serial ports in the autoexec.bat file on the old PS/2? Another possibility is that the clone you are running now is using a less capable UART (16450 instead of 16550, for example) or one of those with a bad FiFo buffer...

I don't think the issue is the port, but rather is the speed of the underlying machine This is a problem that has bitten various old PC games. They made assumptions about the hardware that were true when they wrote the game but aren't true now, and the new hardware is much faster. The game fails to run because the underlying system is too fast. You may want to look at TameDOS, which was written to solve problems like this by slowing the host machine. It installs and runs as a TSR.

[Freedos-user] IBM PS/2 clone system - UPDATE
Hey everyone! The users that helped me may remember, but for the new entries, I'm using FreeDOS 1.2 on a machine to create a clone system to a 1987 IBM PS/2 computer, in order to make it work with a metal analyzer and have a newer and more reliable system. The floppy drive on the IBM came back to life, and I was able to retrieve all the data on 7 1.44mb floppy disks. I copied everything on the FreeDOS machine and the program works! But... there are some issues with the serial ports. I am trying to figure out the issue, but I guess the serial port on the clone system is too fast for the metal analyzer hardware, and the software gets stuck on a "Configuring ICS..." screen that on the IBM lasts about 3 seconds and then launches the full program. Can someone help me on this? I tried exploring the MODE command, but I couldn't figure out much... Also, big news, I was able to copy all the data on a USB stick thanks to FreeDOS (It is supported natively? I did not know that!) so all my data is secure now! That was my main concern. Thanks everyone for the future replies! Greetings from Italy Mattia Limonta ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
