Escaping
DEFINITION: An escape sequence is a sequence of characters that does not represent itself when used
inside a character or string literal, but is translated into another character or a sequence of characters.
Property values and method parameters can contain characters which are used as control characters in the
protocol. They must be escaped. The escape character is the backslash (‘\’) and escaping means injecting
a backslash before the character that should be escaped (like in C language).
The original message: CALL /MEDIA/UART/P1:sendMessage(Set(01))
The escaped message: CALL /MEDIA/UART/P1:sendMessage(Set\(01\))
