This document introduce the protocol used between Basalt Presenter and Basalt Trainer.
If there is no specific description, the endian of data is **native endian**, and the alignment also is native.
Because all data are transmitted in local machine, so we use native layout.
## Command Protocol
Before introducing command protocol, it would be better to the priniciple,
that Presenter is the slave application, and Trainer is the master application.
Command protocol is tramsmitted by system named pipe.
The name of pipe is `\\.\pipe\ed0e3f1f-d214-4880-9562-640bce15e72e` on Windows
or `/tmp/ed0e3f1f-d214-4880-9562-640bce15e72e` on POSIX.
