As the input data of serial communication is random,
does CodeSys have a trigger bit to read buffer for Read FB of free serial communication (RS485/RS422/RS232)?
It looks like that,when the input buffer of COMx get a data package,it send a trigger signal to ask Read FB to read accordingly,in that case, we can trigger the Read.xExcute timely.
