HS XMODEM is a software library in C (supplied with full source code) that provides a programmer with the off-the-shelf support for XMODEM protocol data transfer capability. Support for both sender and receiver are provided. Other features include 1024 block size vs 128, CRC vs checksum, configurable timers and retries

* HOW IT WORKS:
When user application initlialises HsXmodem library, it provides interface callbacks for the services used by Xmodem protocol module: timer management, serial transmission and reception, memory management, event callbacks. 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

As a backup or an alternative to TFTP, Xmodem is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.

* FEATURES:
- Xmodem Sender and Receiver
- 128 and 1024 block size
- Checksum and CRC option
- Configurable timers
- Configurable number of retries

* HOW TO BUY HS XMODEM LIBRARY:
You can purchase the library online using credit card payment at:

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.

SecureCRT protects passwords, user accounts, and data, combining rock-solid terminal emulation with the strong encryption, broad authentication options, and data integrity of the Secure Shell (SSH) protocol. SecureCRT provides versatile solutions for business, network management, information security, and development tasks, from accessing host-based applications and administering servers to securely accessing behind-the-firewall network resources. SecureCRT supports SSH1, SSH2, Telnet, Telnet/SSL, RLogin, Serial, and TAPI protocols and authentication via password, public-key, X.509 certificates, and Kerberos v5 via GSSAPI. Ciphers include AES, Twofish, Blowfish, 3DES, and RC4. Emulations include VT100, VT102, VT220, ANSI, SCO ANSI, Wyse 50/60, Xterm, and Linux console - all with ANSI color. Multibyte character sets are supported for Japanese, Korean, and Chinese, as are scalable line-drawing fonts. SecureCRT has a multi-session tabbed interface with extensive session management features. Customization options include toolbars, menus, keymaps, and login scripts, as well as fonts, cursors, and color schemes. Named sessions and firewalls let you create session-specific configurations. An optional "FIPS Mode” uses a FIPS 140-2 validated cryptographic library and only allows FIPS-approved algorithms. Other features include the Activator tray utility to minimize desktop clutter, auto logon, printing, Emacs mode, and SOCKS firewall support.
ActiveX scripting support saves time by automating routine configuration tasks. Securely transfer files using SFTP, or by using Zmodem or Xmodem from an SSH1 or SSH2 session. SecureCRT and the SecureFX file transfer client can share global and session options and the host key database so configuring a connection only needs to be done once. SecureCRT includes a 30-day evaluation license for the fully-functional application and technical support.

CRT is a rock-solid Windows terminal emulator for Telnet, RLogin, and Serial protocols that's easy to use and highly customizable. CRT is ideal for accessing host-based legacy applications, querying a database, accessing a BBS, or connecting to a network device to perform configuration tasks. CRT features a multi-session tabbed interface with extensive session management and customization features. Customization options include toolbars, menus, keymaps, and login scripts, as well as fonts, cursors, and color schemes. Named sessions and firewalls let you create individual configurations that can be used on a session-specific basis. The Activator tray utility minimizes desktop clutter while a click on the "New Tab" icon on the toolbar allows you to begin a new session instantly. The Quick Connect feature connects to UNIX, VMS, and Windows servers by entering only a hostname. Choose from a wide range of emulations including VT100, VT102, VT220, ANSI, SCO ANSI, Wyse 50/60, Xterm, and Linux console – all with ANSI color. Multibyte character sets are supported for Japanese, Korean, and Chinese, as is support for scalable line-drawing fonts and character attributes including VT line-drawing symbols, bold, underline, reverse and blink, and double-width and double-height fonts. Powerful scripting capabilities, including ActiveX scripting support for VBScript and other scripting languages, save you valuable time by automating routine configuration tasks. Dialer support through Windows TAPI allows saving dial-up connections in session information. Other features include Zmodem and Xmodem file transfers, auto logon, Emacs mode, SOCKS and generic firewalls, and excellent support for transparent pass-through printing. CRT includes a 30-day try-before-you-buy evaluation license for the fully functional application and access to VanDyke Software technical support.
