ID Field Values (continued)
ITC_NVPARM_DISPLAY_TYPE
This IOCTL returns the device’s display type. One byte is returned in the buffer pointed to by the lpOutBuffer
parameter.
ITC_NVPARM_EDG_IP
This IOCTL re turns the device Ethernet debug IP address. Four bytes are returned in the buffer pointed to by the
lpOutBuffer parameter.
ITC_NVPARM_EDBG_SUBNET
This IOCTL returns the device Ethernet debug subnet mask. Four bytes are returned in the buffer pointed to by the
lpOutBuffer parameter.
ITC_NVPARM_ECN
This IOCTL returns ECNs applied to the device in a bit array format. Four bytes are returne d in the buffer pointed
to by the lpOutBuffer parameter.
ITC_NVPARM_CONTRAST
This IOCTL returns the device default contrast setting. Two bytes are returned in the buffer pointed to by the
lpOutBuffer parameter.
ITC_NVPARM_MCODE
This IOCTL returns the manufacturing configuration code for the device. Sixteen bytes are
returned in the buffer pointed to by the lpOutBuffer parameter.
ITC_NVPARM _VERSION_N UM BER
This IOCTL returns the firmware version for various system components. These values for the ClassId field of the
PARMS structure are allowed when ITC_NVPARM_VERSION_NUMBER is used in the id field:
S VN_CLASS_KBD Returns a five-byte string, including null terminator, that contains an ASCII value which
represents the keypad microprocessor version in the system. The format of the string is x.xx with a terminating null
character.
S VN_CLASS_ASIC Re turns a five-byte string, including null terminator, that contains an ASCII value which
represents the version of the FPGA firmware in the system. The format of the string is x.xx with a terminating null
character.
S VN_CLASS_BOOTSTRAP Returns a five-byte string, including null terminator, that contains an ASCII value
which represents the version of the Bootstrap Loader firmware in the system. The format of the string is x.xx with a
terminating null character.
ITC_NVPARM_INTERMEC_SOFTWARE_CONTENT
This IOCTL reads the manufacturing flag bits from the non-volatile data store that dictates certain software
parameters. A BOOLEAN DWORD is returned in the buffer pointed to by lpOutBuffer that indicates if Intermec
ContentisenabledintheXIPregions.TRUEindicatesthatitisenabled.FALSEindicatesthatitisnotenabled.
ITC_NVPARM_ANTENNA_DIVERSITY
This IOCTL reads the state of the antenna diversity flag. A BOOLEAN DWORD is returned in the buffer pointed
to by lpOutBuffer that indicates if there is a diversity antenna installed. TRUE indicates that it is installed. FALSE
indicatesthatitisnotinstalled.
ITC_NVPARM_WAN_RI
This IOCTL reads the state of the WAN ring indicator flag. A BOOLEAN DWORD is re turned in the bu ffer
pointed to by lpOutBuffer that indicates the polarity of the WAN RI signal. TRUE indicates active high. FALSE
indicates active low.
