6 UnitechAPI.DLL
In HT6XX/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
HT6XX/PA96x/PA982. However, it will make RS232 port useless if user want to connect
HT6XX/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.
