APL via TCP
APL can utilize a standard raw TCP stream socket connection initiated by the client device
(KDT750) to a database server. In this method, the client opens the socket to the server,
sends the bar code data, receives a reply packet from the server and closes the connec-
tion. This reply is then parsed and the data is displayed on the LCD.
APL via TCP Features
• Fast communication with low overhead
• Simple, human readable packet format
• Extensible model for future custom enhancements
• Easily parsed with server-side scripts
• Fully functional server application source code provided
APL via HTTP
To allow for integration in environments where adding network services or opening new TCP
ports is not an option, APL can utilize the standard Hypertext Transfer Protocol's (HTTP) POST
operation. Here, APL acts as if it was a simple web client connecting to an HTTP service on
the server.
APL via HTTP POST Features
• Easily integrates into existing web server environments
• Simple web based development for server-side software
• Easily parsed with server-side scripts
• Fully functional server application source code provided
