LangBox For Cyrillic

 The Product

LANGBOX-CYR is a product designed specifically to support all languages that use the Cyrillic alphabet. In addition to English, these languages are supported with keyboard mapping, system messages, screen and display management, collating sequences, and date and time routine services.

LANGBOX-CYR is an extension to the UNIX operating system Kernel. A virtual driver or a STREAMS module is added to the kernel, processing on exceptional basis the Cyrillic characters. A special shell and a variety of commands are added to complete the package.


LANGBOX-CYR will permit staff in your office to share and use existing UNIX applications in Cyrillic with little or no adjustment. With LANGBOX's load and go transparency a user can obtain an English word processor, data base manager, spreadsheet or any 8-bit clean application and use it immediately - with no modification to the application - in Cyrillic. He/She can even mix Cyrillic and English characters and text within one document with a keystroke. Such bilingual power and elegance was never before possible under UNIX.
