/**
|
|
* Implements the client-side of the RCP/VD-Protocoll -- i.e. the communication with AVS_Export.
|
|
*
|
|
* The Idea of this class is simply to provide
|
|
* 1. Methods to issue commands
|
|
* 2. Signals for incoming replys (defined in IVdComm).
|
|
* 3. Possibly reconnecting when the connection got lost.
|
|
* Observing the connection using KeepAlives is done by VdSession.
|
|
*
|
|
* A command can have multiple replys and thus can trigger multiple signals.
|
|
* The layer above is then responsible to keep track of certain states in the protocol
|
|
* and to e.g. assemble the received information into a more abstract format.
