Korean Solaris STREAMS

The Korean Solaris operating environment uses the modular nature of STREAMS to support Korean. In addition to the traditional TTY modules, this product implements code conversion in STREAMS. Hangul-Hanja conversion is typically supplied by many existing Korean TTYs and is not available in the Korean Solaris TTY environment.

The Korean Solaris operating environment enhances the traditional modules. Its line discipline handles proper cursor movement for wide characters as well as normal protocols. The Korean Solaris software code conversion modules convert between two different character code formats such as between Packed (also called Combination code of KS C 5601-1987) and EUC (called Completion code).

Code conversion depends on the appropriate flags or parameters being set. For example, if a Packed code terminal is being used, the input from the terminal is converted to EUC and the output to the terminal is converted to Packed code.

The major modules that can be pushed onto the stream are ldterm, kpack and kjohap:

• ldterm(7) is a generic EUC line discipline module. It processes all normal line discipline functions and also handles proper cursor movement and backspacing for wide characters (EUC).

• kpack controls code conversion between Combination code of KS C 5601-1987 and EUC.

• kjohap controls code conversion between Combination code of KS C 5601-1992 code and EUC.
