LangBox For Farsi

 The Product

LANGBOX-FAR is a product designed specifically to support the Farsi (or Persian) alphabet. In addition to English, this language is supported with keyboard mapping, fontset, system messages, screen and display management, collating sequences, and date and time routine services.

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


LANGBOX-FAR will permit staff in your office to share and use existing UNIX character based applications in Farsi with little or no adjustement. With LangBox International'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 Farsi.
