Developer:LPEC
Introduction
Linn's UPnP products can be controlled over a home network in an ever increaing number of ways. The primary means of control is, of course, UPnP itself, which subdivides product control into smaller units called services. A DS product, for instance, will provide some standard UPnP AV services:
- AVTransport
- RenderingControl
- ConnectionManager
and additional Linn-specific services, such as:
- Ds
- Volkano
- Product
- Ui
It is possible in Bute and later software releases to control a Linn UPnP product using an alternative mechanism known as the Linn Protocol for Eventing and Control.
This is a basic Telnet-like protocol, which relies on the developer knowing in advance, or having discovered by some means, the TCP/IP of the device to be controlled. Knowing this, LPEC can be accessed by creating a raw socket session to port 23 of the device.
The rest of this document describes the format of the messages that LPEC expects and delivers.
