When Promi-ESD encounters a character ‘+’ from host, it
stops the data
transmission and waits for next 2
characters. If the next 2 characters aren’t both ‘+’, it
restart to transmit data including the first ‘+’ as well. If
not, it converts the operation status to ‘Standby’.
If the data from host includes ‘+++’, it will convert the
operation status to ‘Standby’ unexpectedly. Notice that
Promi-ESD holds data transmission when it encounters
‘+’, until receiving next character.
‘+’ is an escape sequence character by default, which is
changeable by AT+SETESC.
