The htt process must be running before an application starts in order for the application to use the htt input method server to receive Traditional Chinese input. The C locale does not require htt. If you change the default locale from C to another locale that requires htt, you must start htt in the same terminal window. You can start htt with a command such as the one shown in the following example.
system% /usr/openwin/bin/htt -if twle -xim htt_xbe & |
When the locale is set to zh_TW or zh_TW.BIG5, htt is started automatically when the Traditional Chinese windowing environment starts. In CDE, htt is started from the /usr/dt/config/Xsession.d/0020.dtims script. This script is executed by Xsession, which runs at every initialization stage upon a user's login from dtlogin. This script ensures that htt is started before other applications in CDE.
