This function initializes the serial device.

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 Values

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

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Developer defined.
Library: Serial.lib.
