10.7 Basic format of the dedicated protocols

Replay manages up to four dedicated protocols.
The definition of which of these four protocols must be used by the serial connection, is set

The introduction of CheckSum at the end of the block of data and characters of CR +

•
The character at the beginning of the string ENQ (0x05) may be replaced by the
character '#'. This makes the command string perfectly legible.
•
The address is not managed on RS232, set it at 00.
