The Korean Solaris Operating System 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 System enhances the traditional modules. The line discipline of the operating system handles proper cursor movement for wide characters as well as normal protocols. The Korean Solaris code conversion modules convert between two different character code formats. For example, Packed format, combination code of KS C 5601-1987, can be converted to EUC format, 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 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). See ldterm(7M) for more information.
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.
