Is Spyware and/or Adware messing up your internet connection after you have uninstalled it?

Has your internet connection slowed down and you just don't know why?

Have you used an Internet Optimizer that just didn't optimize your internet, instead it made it slower?

If you answered yes to any of the questions above, then XP TCP/IP Repair may help fix your internet connection and possibly even protect your privacy.

XP TCP/IP Repair is a Graphical User Interface (GUI) for commands in Windows XP that repair your TCP/IP registry settings and your Winsock LSP's.

Instead of having trying to remember long confusing command line commands you can now just click a button.

What is an LSP?

Layered Service Providers (LSP) are small pieces of software that can be added or inserted into the Windows TCP/IP handler by other software. Data outward bound from your computer to a legitimate destination on the Internet can be intercepted by an LSP and sent somewhere other than where you intend it to go.

HS POP3 Lite 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 TFTP is a software library in C (supplied with full source code) which implements Trivial File Transfer Protocol (TFTP) over UDP socket layer according to RFC 1350. Support for client and server side for both file get and put are provided. Optional 1024 block size vs 512 size configuration is available

HOW IT WORKS: When user application initlialises Hs TFTP library, it provides interface callbacks for the services used by HS TFTP protocol module: timer management, memory management and event callbacks. This architecture makes it easy to port HS TFTP protocol module to any environment. HS TFTP internally at a lower layer interfaces to HS Sock library which provides UDP transport services. User application need not worry about Winsock - HS TFTP does all transmission, reception and event handling over socket layer.

TFTP module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. 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.

HS X.25 is a software library in C (supplied with full source code) which 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.

Main Features: * DTE operation * DCE operation * Multiple layer 2 links * 4095 VCs per link * SVC supported * X.25 version: ITU-T (formerly CCITT) 10/96 * outgoing calls * incoming calls * max packet lenght 1024 * all X.25 timer and counters implemented * interrupt packets supported * Statistics * Trace Function *

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.
