PowerTCP Winsock Tool

These easy-to-use ActiveX Controls provide the building blocks you need for basic Internet application development. Superior buffer management, the use of variants supporting String and Byte-array data, and optional blocking use makes this tool exceptionally complete and versatile.

• TCP Control - Use to implement any upper-layer protocol that is based on a TCP data stream.
• Daemon Control - Use to build a server. Can accept an unlimited number of connections that can be assigned to dynamic TCP Controls for stream management. (Check out the Server Tool for a turn-key Server Control that makes server applications ever easier to write!)
• UDP Control - Use to send and receive User Datagrams and raw IP Datagrams. Broadcast operation is supported.
• Ping Control - Send and receive ICMP echo (Ping) messages. Dynamically discover if a host is reachable.
• DNS Control - Send and receive Domain Name Server messages. Forward lookup, reverse lookup, and mail server lookup is supported.
• RAS Control - Use to establish a Remote Access Server (RAS) connection to a remote communications server.

Benefits & Features

• TCP Search Method supports variable length records and line processing, eliminating the need to search for termination characters and simplifying buffer management.
  
• TCP Fill Method supports fixed length binary records, simplifying buffer management and reducing the code needed to send and receive binary structures.
  
• UDP supports raw datagrams, providing the ability to access advanced protocols like ICMP.
  
• RAS can be invisible or visible, simplifying user configuration.
  
• DNS Control bypasses Winsock system services, so you can query ANY Domain Name Server on the Internet.
  
• Ping Control will confirm the presence of any host on the Internet, even if hosted server applications are not responding!
  
• Controls can operate on separate threads, so Server Applications can be written using apartment model multi-threading features.
