From the developer: "Socket Workbench is a tool designed to analyze socket communications. You can configure Socket Workbench to be a socket client or socket server, or you can place it in the "pass-through" mode in which you can intercept socket communications without packet sniffing. Send and receive both text and binary that you have typed, or read from a file. The program also includes a library of common protocols helpful for analyzing HTTP and SMTP.New in version 3.1 - Significantly improved user interface. - Sent and received data is displayed on the one screen. - Up to 50% faster - Either incoming data or outgoing data or both can be filtered out - Vastly improved logging of data. Log in Hex or AscII and include time stamps to the millisecond - All logging is recorded to the millisecond - Expires after 30 days instead of nag screen"

This trial verion displays a small nag screen when closing down. Registration removes this limitation and costs $100.
