6.1.19. CP210xSetDualPortConfig

Description:

Sets the current port pin configuration from the CP210x device. SetDeviceMode() must be called

before calling this function.

Supported Devices:

CP2105

Location:

CP210x Manufacturing DLL

Prototype:

CP210X_STATUS

CP210x_SetPortConfig(HANDLE

Handle,

LPVOID

DualPortCon-

fig)

Parameters:

1. Handle—Handle to the device as returned by CP210x_Open()

2. DualPortConfig—Pointer to a DUAL_PORT_CONFIG structure

Return Value: CP210X_STATUS = CP210X_SUCCESS,



CP210X_INVALID_HANDLE,



CP210X_DEVICE_IO_FAILED,



CP210X_UNSUPPORTED_DEVICE

6.1.20. CP210x_GetDeviceProductString

Description:

Returns the Product Description String of the String Descriptor of a CP210x device. If the Convert-

ToASCII parameter is set, the string will be converted to ASCII format before being returned to the

caller. The character size limit (in characters, not bytes), NOT including a NULL terminator, is

CP210x_MAX_PRODUCT_STRLEN.

Supported Devices:

CP2101, CP2102, CP2103, CP2104, CP2105, CP2108

Location:

CP210x Manufacturing DLL

Prototype:

CP210x_STATUS CP210x_GetDeviceProductString( HANDLE Handle,



LPVOID Product, LPBYTE Length, BOOL ConvertToASCII=TRUE )

Parameters:

1. Handle—Handle to the device to close as returned by CP210x_Open().

2. Product—Pointer to a buffer returning the Product String value.

3. Length—Pointer to a BYTE value returning the length of the string in characters (not bytes),

NOT including a NULL terminator.

4. ConvertToASCII—Boolean flag that tells the function whether the string needs to be converted

to ASCII before it is returned to the caller. The flag is set to TRUE by default (i.e., the caller is

expecting the string in ASCII format).

Return Value: CP210x_STATUS = CP210x_SUCCESS,



CP210x_INVALID_PARAMETER,



CP210x_INVALID_HANDLE,



CP210x_DEVICE_IO_FAILED

6.1.21. CP210xSetQuadPortConfig

Description:

Sets the current port pin configuration from the CP2108 device.

Supported Devices:

CP2108

Location:

CP210x Manufacturing DLL
