Any application that uses the IM server to receive Korean characters must find htt running before the server can receive Korean character input. If the default locale is C, which does not require htt, and you change from C to another locale in a single Terminal, for example, you must start htt with a command line like the following:
system% /user/openwin/bin/htt -if kole -xim htt_xbe &
With the locale set to ko_KR.EUC, htt starts automatically when the Korean windowing environment is started. In CDE, htt is started from a script, /usr/dt/config/Xsession.d/0020.dtims. The script is executed by Xsession, which runs at every initialization stage when you log in from dtlogin. The script ensures that htt is started before other applications in CDE.
