In this case the message starting char and the message closing char will be entered just one time, in the string beginning
and at the end.
All the commands in string will not execute until the closing char will be entered.
Separate response will be sent for every command in the chain.

Design note: transparent supporting for protocol 2000 will be implemented by switch protocol command from protocol 3000
to protocol 2000, in protocol 2000 there is already such a command to switch protocol to ASCII protocol (#56 : H38 H80 H83
H81).
