IO Serial Port Communicator

Aim:

The task is to create a demonstrative version of a program, that is responsible for connecting to the serial port with provided parameters, send new data (binary or text), have the option to see the last message and have the ability to safely disconnect.

Data required for connection:

Port Name
Baud Rate
Parity
Data Bits
Flow Control
Stop Bits

Hints:

You can use the help of this article:Programming Finite State Machines, when it comes to deciding on the structure of the program. You can also read more on Macrofilters

Used Filters

Icon	Name	Description
	ChooseByPredicate	E.g. to choose GREEN color to visualize correct objects or RED to visualize defective ones.
	ConcatenateStrings	Joins two or more strings into a single one.
	ConcatenateStrings_OfArray	Joins multiple strings into a single one.
	FormatIntegerToString	Useful for preparing a number for display or communication with specific number of digits, sign etc.
	LastMultipleObjects	Returns an array of most recent objects.
	Loop	Put this filter into a task that should have a loop, but does not have any other loop generators (e.g. GrabImage).
	ParseInteger	Returns the integer number represented by a string.
	ReadIntegerArrayFromBuffer	Reads an array of integer values in specified binary format from a byte buffer.
	RemoveNils	This filter is useful e.g. when inspecting multiple objects while some of the inspections may fail (Nil result). RemoveNils is used to ignore the failed cases in the final result.
	SerialPort_Config	Configures the serial port.
	SerialPort_ReadBuffer	Reads raw binary data from serial port.
	SerialPort_WriteBuffer	Writes raw binary data from a byte buffer to serial port.
	SerialPort_WriteString	Writes string characters to serial port.
	SplitString	Divides the input string into an array of strings using the specified delimiters.
	WriteIntegerArrayToBuffer	Converts an array of integer values into specified binary representation and writes it to a byte buffer.
