The following functions have been improved (extended buffer support):
UFR_STATUS DL_API APDUHexStrTransceive(const char *c_apdu, char **r_apdu);
UFR_STATUS DL_API APDUPlainTransceive(const uint8_t *c_apdu, uint32_t c_apdu_len, uint8_t *r_apdu, uint32_t *r_apdu_len);
UFR_STATUS DL_API APDUTransceive(uint8_t cls, uint8_t ins, uint8_t p1, uint8_t p2, const uint8_t *data_out, uint32_t Nc, uint8_t *data_in, uint32_t *Ne, uint8_t send_le, uint8_t *apdu_status);
UFR_STATUS DL_API APDUHexStrTransceiveM(UFR_HANDLE hndUFR, const char *c_apdu, char **r_apdu);
UFR_STATUS DL_API APDUPlainTransceiveM(UFR_HANDLE hndUFR, const uint8_t *c_apdu, uint32_t c_apdu_len, uint8_t *r_apdu, uint32_t *r_apdu_len);
UFR_STATUS DL_API APDUTransceiveM(UFR_HANDLE hndUFR, uint8_t cls, uint8_t ins, uint8_t p0, uint8_t p1, const uint8_t *data_out, uint32_t Nc, uint8_t *data_in, uint32_t *Ne, uint8_t send_le, uint8_t *apdu_status);

Improvement is valid from the firmware version 3.9.44

Finished implementation of the "APDU Transceive" in the firmware (using APDU_TRANSCEIVE command).

UFR_STATUS DL_API SetISO14443_4_Mode(void);
UFR_STATUS DL_API SetISO14443_4_ModeM(UFR_HANDLE hndUFR);

Finished NFC T4T support for NDEF messages using APDU support through "ISO14443-4 half-duplex block transmission protocol (i_block, r_block and s_block)".
All functions in library that support NDEF messages now working with NFC T4T cards.

Added functions:
UFR_STATUS GetAdHocEmulationParams(uint8_t *ThresholdMinLevel, uint8_t *ThresholdCollLevel,
								   uint8_t *RFLevelAmp, uint8_t *RxGain, uint8_t *RFLevel);
UFR_STATUS SetAdHocEmulationParams(uint8_t ThresholdMinLevel, uint8_t ThresholdCollLevel,
								   uint8_t RFLevelAmp, uint8_t RxGain, uint8_t RFLevel);
UFR_STATUS GetAdHocEmulationParamsM(UFR_HANDLE hndUFR,
								    uint8_t *ThresholdMinLevel, uint8_t *ThresholdCollLevel,
								    uint8_t *RFLevelAmp, uint8_t *RxGain, uint8_t *RFLevel);
UFR_STATUS SetAdHocEmulationParamsM(UFR_HANDLE hndUFR,
								    uint8_t ThresholdMinLevel, uint8_t ThresholdCollLevel,
								    uint8_t RFLevelAmp, uint8_t RxGain, uint8_t RFLevel);

Dependency for these functions: uFR firmware - min. version 3.9.35

Added functions:
UFR_STATUS AdHocEmulationStart(void);
UFR_STATUS AdHocEmulationStop(void);
UFR_STATUS GetExternalFieldState(uint8_t *is_field_present);

UFR_STATUS AdHocEmulationStartM(UFR_HANDLE hndUFR);
UFR_STATUS AdHocEmulationStopM(UFR_HANDLE hndUFR);
UFR_STATUS GetExternalFieldStateM(UFR_HANDLE hndUFR, uint8_t *is_field_present);

choosing mode depends of communication speed in ReaderOpen()

> fixed in rs232_serial_port_init() : close() port if error occurred

* BUGFIX: timeout problem on 64 bit systems
