HS NTP is an application library in C (supplied with full source code) that will implement the client side of Network Time Protocol (POP3) over UDP socket layer according to RFC1769 and RFC1305. HS NTP Library will allow your application to synchronise local system time to remote NTP server time.

How it works:
First user application calls HS NTP initialisation function supplying pointers to callback functions in user code for timer management and for reporting NTP events to user.

To obtain time difference between local system and remote NTP server, the user application calls HsNtpGetTime function, specifying NTP server name or IP address and source UDP port to use.

HS NTP library then resolves the server name, formats and sends NTP time request packet according to RFC1305 and RFC1769 standard. Once HS NTP has received NTP time reply from NTP server it analyses the reply and reports the resulting time difference to user application via callback function. The parameters to this event callback contain the offset value in seconds necessary to apply to local clock in order to synchronize it to the time at remote NTP server.

Modular design makes it easy to port HS NTP protocol module to any environment. HS NTP internally at a lower layer interfaces to HS Sock library which provides UDP transport services. User application need not worry about Winsock - HS NTP does all transmission, reception and event handling over socket layer.

Here are some key features of "HS NTP C Source Library":

· NTP Client Operation
· Server name resolution
· Non-Blocking Operation

HS X.25 is a useful software library in C (supplied with full source code) that implements ITU-T recommendation X.25 - Interface between Data Terminal Equipment (DTE) and Data Circuit-terminating Equipment (DCE) for terminals operating in the packet mode and connected to public data networks by dedicated circuit.

HS X.25 internally at a lower layer interfaces to HsDL library. HsDL library is Data Link layer abstraction. When HS X.25 is ported into environment with LAPB or LAPD as data link layer, only HsDL module needs to change.

HsDL links directly to HsSock module (also included in this package) - Winsock interface component that provides reliable TCP transport services similar to LAPB / LAPD / HDLC.

HsX25 as provided to customer may be used immediately in X.25 over TCP (XOT) solution or it may be used with traditional LAPB or LAPD in which case only HsDL will need to be modified.

When it is appropriate to send next block of data HS TFTP will get next memory block from user application. Similarly, when data has been received HS TFTP module will get the next block of memory from user application to store data into

Along with XMODEM or as an alternative, TFTP is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.

This architecture makes it easy to port Xmodem protocol module to any environment

Xmodem module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. When it is appropriate to send next block of data Hs Xmodem will get next memory block from user application. Similarly, when data has been received Hs Xmodem module will get the next block of memory from user application to store data into

HS Crypto is a useful and reliable software library in C (supplied with full source code) which offers a programmer an API to several data encryption / decryption algorithms. Implemented methods include the use of 2 either pre-defined or dynamically generated translation tables, an XOR-based stream cipher method with random dynamic key, plus the library includes RFC1321 MD5 Message Digest Algorithm.

The table encryption is implemented via the use of two either pre-defined translation tables or any of the 2 or a combination of dynamically generated translation tables. Decryption is implemented in a similar way using reverse tables.

The stream cipher method uses randomly generated key which must be known to both receiver and transmitter to encode each byte with a rotating byte of the key

RFC1321 MD5 algorithm generates a 16 byte data signature which is unique to the input data. This may be used for data integrity checking or in digital signature applications.

is a useful and reliable software library in C that provides a programmer with a lossless compression / decompression algorithm based on RLE (runtime length encoding). The library may be used in telecommunications application or for fixed data compression.

Runtime Length Encoding (RLE): HS Compress library operates in buffer mode. It monitors the buffer data for presence of any four or more consecutive repetitions of the same character. If detected, the compression code, character and length are stored in the output buffer.

HS FTP Client C Source Library description
HS FTP Client C Source Library offers you a software library in C that implements the client side of FTP over TCP socket layer HS FTP Client C Source Library offers you a software library in C (supplied with full source code) that implements the client side of the File Transfer Protocol over TCP socket layer according to RFC 959. The library allows a user application to connect to remote FTP servers, traverse server directory structure and send and receive files. The HS FTP protocol module supports passive mode data connections, user / password authentication and a number of commonly used FTP commands: USER, PASS, TYPE, PASV, LIST, CWD, RETR, STOR.

To connect to remote FTP server, the user application calls HsFtpCliConnect function, supplying connection parameters, such as remote FTP server name or IP address, username and password for authentication etc. It also supplies a pointer to callback function that the HS FTP module uses to communicate with the user code.

When the control FTP connection is established and HS FTP has successfully passed user / password FTP account authentication phase, the user application is asynchronously notified via user event callback function with HS_FTPCLI_USR_EV_LOGGEDIN event.

At this point, the user application can request remote FTP server directory listing using HsFtpCliList function, request to change current directory at remote FTP server with HsFtpCliChDr function or transfer binary files to and from remote FTP server with HsFtpCliSendFile and HsFtpCliGetFile functions.

The result of each operation is asynchronously notified via event callback with corresponding events.

HS NMEA GPS is a useful and reliable software library in C which provides a PC-based user application with access to a Global Positioning System (GPS) receiver via a serial communications port. HS NMEA GPS continuously receives navigational information from the receiver according to NMEA-183 (National Marine Electronics Association, Interface Standard 0183). HS NMEA GPS library will operate with any NMEA-183 compliant receiver with serial RS232 interface.

HS GPS library continuously reads asynchronous data stream from a serial port and analyses the information to recognize and decode NMEA-183 Protocol sentences. After each message is received it is checked for integrity by comparing the received and the calculated checksum. The NMEA sentence fields are then converted from ASCII values into C structure variables and passed up to user application code.
