Hello! Are there any functions that I can use in ST (or practically any other language from IEC 61131) to write to the serial port and to recieve data from it. As far as I know, all PLCs have a serial connector so it would be logical to have native support for it. I already tried to search the NET, but without luck. Can you please help me where should I look?

TIA!
