1/6/2010
This function initializes the serial device.
Syntax
HANDLE COM_Init(
ULONG Identifier
);
Parameters
- Identifier
[in] Port identifier. If a driver is loaded by Device.exe, this value points to a string containing the registry key in HKEY_LOCAL_MACHINE\Drivers\Active. If the device driver is loaded by a call to the RegisterDevice function, this value is the dwInfo value passed into the call to RegisterDevice.
Return Value
Returns a pointer to the beginning of the list of serial devices, which is then passed as a device handle into the entry points COM_Open and COM_Deinit.
Remarks
This function is called to initialize a device when it loads. This function postpones memory allocation and device power until an application calls the driver's XXX_Open function.
