• [command] :Command identifier; a 3-byte identifier (ASCII code: symbols, numbers,
upper-case letters) is sent as the command.

Outline of send procedure from controller
1. The send command starts with STX (start of text = 02h). The command is then identified
by COMMAND which follows and the data is added as required.
The format ends with ETX (end of text = 03h).
2. When a different command is to be sent, a response is awaited from the VTR, and then
the command is sent. (See page E-9)
3. If STX is sent again before ETX is sent, the receive data buffer inside the VTR is cleared.
A command error is returned to the controller, and the data is newly processed with STX
which was received again at the head.
