Command interpreter, systems for fixed code and read/write commands
8.2.1
Command structure
The mode commands described below behave in the same way as the corresponding
standard commands. For each mode command received, with the exception of the
RST command, the control interface unit responds with a message transmitting the
status of the control interface unit. The commands are transmitted to the control inter-
face unit in the form of data in a SEND message. The commands are encoded byte
by byte. The control interface unit acknowledges the commands with a further SEND
message, in which the status corresponding to the command is transmitted.
