-6 UnitechAPI.DLLIn HT6XX/PA96x/PA982, Unitech create UnitechAPI.DLL to provide some special functioncall which are different from standard Microsoft API. For example, RS232 is defined as hostcommunication port with PC via ActiveSync, so it will automatically envoke ActiveSyncprogram to do communication with PC when RS232 cable is plugged intoHT6XX/PA96x/PA982. However, it will make RS232 port useless if user want to connectHT6XX/PA96x/PA982 with any device with RS232 interface. RS232Event.DLL providesfunction call for user to disable ActiveSync function over RS232 port to let user directlycontrol 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” buttonfrom task bar to setup terminal or execute any application on WinCE terminal, so it meanthat operator can change, modify or delete any setting. If system developer don’t wantoperator to do any extra operation beside application, Unitech provide function call toprovides ability to disable/enable task bar, keyboard and etc.You can get demo program from HT6XX/PA96x/PA982 technical binder zip files from\programming\UnitechAPI6.1 Disable ActiveSyncFunction Description:After called this function, HT6XX/PA96x/PA982 will not automatically execute ActiveSyncprogram( “repllog.exe”) when user plug RS232 cable into HT6XX/PA96x/PA982.Function call:BOOL RS232EventEnable (VOID);Return code:=TRUE OK=FALSE Fail6.2 Enable ActiveSyncFunction Description:After called this function, HT6XX/PA96x/PA982 will automatically execute ActiveSync program( “repllog.exe”) again when user plug RS232 cable into HT6XX/PA96x/PA982.Function call:BOOL RS232EventEnable (LPTSTR);Parameter (Input):String buffer and content should be “REPLLOG.EXE”. If user assign other program, it will invokeuser defined program rather than “REPLLOG.EXE”Return code:=1 OK=2 File not found
