HS POP3 is a software library in C (supplied with full source code) which implements the client side of Post Office Protocol Version 3 (POP3) over TCP socket layer according to RFC 1939. Among other features, the library supports user authentication, reception of basic internet headers and text, message deletion and statistics
First user application calls HS POP3 initialisation function supplying pointers to callback functions in user code for memory amd timer management and for reporting POP3 events to user.
To receive email messages from any POP3 RFC1939 compliant server, the user application calls HsPop3GetMail function, specifying mail server name or IP address and login user name and password.
HS POP3 library then resolves the server name, connects to it, receives and message scan list. according to RFC1939 standard. Once HS POP3 has a unique message ID from the server, it reports this message ID to user application via callback function. The user application returns a specific value if it wants to receive this message. At this point HS POP3 will request necessary amount of memory for the message and will receive complete message into the buffer. Once message is received, the user code is notified with a callback and a message structure, containing full message pointer, message length, start of text pointer, length of headers and separate parsed out header information: from field, date field, message id field and subject field. This process is repeated until all messages are received. HS POP3 library can also delete messages from server if this option is specified.
HS POP3 Library incorporates the necessary state machine, transparency procedures, and server response processing required to comply to a simple and robust POP3 client implementation.
Modular design makes it easy to port HS POP3 protocol module to any environment. HS POP3 internally at a lower layer interfaces to HS Sock library which provides TCP transport services.

HS SMTP is a software library in C (supplied with full source code) which implements the client side of Simple Mail Transfer Protocol (SMTP) over TCP socket layer according to RFC 821. Support for transfer of basic message header and text is provided
From version 1.1, HS SMTP supports ESMTP extension for LOGIN Authentication using Base64 encoding and message sending to multiple recipients from address list.
From version 1.2 HS SMTP supports sending binary file attachments using MIME version 1.0 base64 encoding
To send a text email message to any address on the internet, the user application calls a single function HsSmtpSendMail, specifying mail server name or IP address, sender address, recipient address, message text buffer and length, subject, cc and an event callback function to use for reporting of operation result and server errors.
HS SMTP library then resolves the server name, connects to it and transmits the message according to SMTP RFC 821 protocol. HS SMTP Library incorporates the necessary state machine, transparency procedures, and server response processing required to comply to a simple and robust SMTP client implementation.
Modular design makes it easy to port HS SMTP protocol module to any environment. HS SMTP internally at a lower layer interfaces to HS Sock library which provides TCP transport services. User application need not worry about Winsock - HS SMTP does all transmission, reception and event handling over socket layer.

Using Modbus Constructor you can quickly create a data management model for any of your Modbus devices. Unlike other available solutions on the market which provide displaying data as columns of abstract numbers of the same type, Modbus Constructor represents each data element exactly as you need. You may define type, format or scale independently. This makes them easy to read and analyze.
In Modbus Constructor you can work with integer, long, float, double, or byte data types. Integer types may be represented as signed, unsigned, HEX or binary. The same register can be represented in various ways. For example, if there are two adjacent registers that contain long numbers, each of these registers can be given additional data fields in which their content will be represented as HEX or unsigned integer.
Data fields corresponding to your data elements (registers or discreet elements) can be arranged to your liking inside the project form window. You can specify size, color, font and caption for each field.
The discreet elements occupying a continuous addresses domain can share the same field, which makes them easier to read and saves time.
In Modbus Constructor you can setup any register data field to perform a linear transformation to convert the internal units into units of any system. For example, if a register contains pressure in mA, i.e. the device receives data from a pressure detector equipped with a current output, the resulting value can be converted to kgf/cm2 or lb/in2.
Modbus Constructor supports automatic requests for all supported functions (01, 02, 03, 04, 05, 06, 15, 16, 22, 23) with individual periods for each one.
You can setup requests to be executed via menus or dialogs. This is a convenient way of setting up control commands, changing parameters and test requests. Any project may be used for querying a device in a Master mode or simulating it in a Slave mode. For the Slave mode you may additionally include a data modification procedure operating according.
