6. UnitechAPI.DLL
In HT660/PA96x/PA982, Unitech create UnitechAPI.DLL to provide some special function call which are
different from standard Microsoft API. For example, RS232 is defined as host communication port with PC
via ActiveSync, so it will automatically envoke ActiveSync program to do communication with PC when
RS232 cable is plugged into HT660/PA96x/PA982. However, it will make RS232 port useless if user want
to connect HT660/PA96x/PA982 with any device with RS232 interface. RS232Event.DLL provides
function call for user to disable ActiveSync function over RS232 port to let user directly control RS232
port.
Unitech also provide several function to enable/disable several system icon and task bar. For WinCE
system, it just like Windows OS platform, user can directly tap “Start” button from task bar to setup
terminal or execute any application on WinCE terminal, so it mean that operator can change, modify or
delete any setting. If system developer don’t want operator to do any extra operation beside application,
Unitech provide function call to provides ability to disable/enable task bar, keyboard and etc.
