You said "I copy these programs from a real computer" which suggests you are running this FreeDOS 1.4 installation on a virtual machine? This could be a virtual machine issue -- note the thread you linked to was also a virtual machine.
Virtual machines are not always perfect, and Borland's Turbo products used some interesting PC features that not all emulators support (or if they do, they may not support them well). For example, while I use QEMU as my virtual machine, the default QEMU behavior does not support all "corner cases" of classic PCs. One of these is how QEMU manages the keyboard, which can make any app built with Borland's TurboVision appear to hang or run really slooooooooowly. QEMU added a fix just a few years ago, but you have to add this to the QEMU command line: -global i8042.kbd-throttle=on With that, I can run Borland TurboPascal, TurboC, and TurboC/C++ just fine in FreeDOS, running on QEMU. (Without that fix, Borland basically hangs on my system -- or if it runs, there's a really long delay between keystrokes, which makes it unusable.) TurboVision was used across all of Borland's products, including TurboBASIC. Other third-party apps also use TurboVision, and those will also be slow until you apply this fix. It's a reminder that virtual machines are not perfect replacements for classic PC hardware. If I want to test something on real hardware, I have a '386 for that. In case you also use QEMU, this is my complete QEMU command line:* qemu-system-i386 -enable-kvm -m 32 -rtc base=localtime -audiodev pa,id=snd -machine pcspk-audiodev=snd -device sb16,audiodev=snd -device adlib,audiodev=snd -global i8042.kbd-throttle=on -drive bus=0,unit=0,media=disk,file=freedos.qcow2 -drive bus=0,unit=1,media=disk,file=files.qcow2 -drive bus=1,unit=0,media=cdrom,file=T2512LIVE.iso -drive bus=1,unit=1,media=cdrom,file=T2512/T2512BNS.iso *This supports SoundBlaster16 and Adlib sound, and emulates a PC speaker. The extra '-device' options define two hard disks (C: and D:) and use both the LiveCD and BonusCD images so I can use both CD's without changing my config.
