Serial Communication over RTP/CDP

- Protocol and Topology Considerations- Linux Reference Implementation- Microcontroller Reference Implementation- Virtual COM Port Concept for MS WinThis pamphlet shares the practical experience with a simple yet versatiledata aquisition and remote control topology using the Real-time Transport Protocolfor IP-based soft real-time machine-to-machine communication.A Control Data Profile for RTP is discussed along with reference applications ofRTP/CDP for bridging serial local bus communication over the Internet Protocol.Furthermore in-depth implementational details are provided for an exemplaryLinux userspace RTP/CDP software as well as for a functional stack andstate machine of a RTP/CDP-to-RS232 adapter using an 8-bit microcontroller.On non-Linux platforms RTP/CDP sessions can be interfaced by virtual COM ports.This concept is discussed in detail and may be combined with the beforementionedadapters to solve the problem of missing physical COM ports in recent computers.
