Switching the keyboard layout in 16-bit DOS applications

Practice



If the keyboard layout in DOS applications does not switch to Russian, even though Russian letters display correctly, then in the registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\KeyboardLayout\DosKeybCodes

change the value of the "00000409" parameter from "us" to "ru".

In addition, in the autoexec.nt file located in Winnt\system32, add the line

lh %SystemRoot%\system32\kb16.com ru

After rebooting, keyboard layout switching in DOS applications will be done with the key combinations Ctrl+left Shift (English layout) and Ctrl+right Shift (Russian).

This method works correctly if, in Control Panel, in the region settings (Regional Options), the "Language settings for the system" parameter has Cyrillic set as Default.
