Widget Designer > Nodes > Syntax TCP- / UDP- / Serial Messages

Via TCP-, UDP- and COM Port nodes incoming or outgoing values can be entered as string, decimal or hexadecimal values.

Example:
Let's say, you would like to express a "Carriage Return" at the end of other values. This control character is used in many codes as a command to move to a new line. On a normal keyboard you have the possibility to press the key [Carriage Return], also known as the return key or enter key, the operating system understands this automatically and translates it into the correct code. When writing strings in ASCII or decimal or hexadecimal language you need to translate the command yourself. Please see the DEC HEX ASCII Table below to find the code for the character.

Use [d13] to enter a carriage return as a decimal value.
Use [h0D] to enter a carriage return as a hexadecimal value.
Use [CR] to enter a carriage return as a ASCII symbol.

Please note: Mostly, you need a "Line Feed" command as well. For two commands you may use this syntax: [d13 d10] respectively [h0D h0A] or [CR LF]. Mixed values are also possible, e.g: Example String[CR d10].
