hello all, please, i need help with rs232; i have no experience with this

are there cases for osp300, where rs232 is used ? please, can you share some examples ?

is it possible to run a program, that uses PUT in 2 ways :
... so to send data through rs232, to whatever peripheral device
... to write data to a file located in MD1; this file has no conection with the perhiperal device

or it does not matter ? thus PUT simply writes data to a file, and i can use that file as :
... passive ( nothing happens )
... active ( somehow associated with rs232 ); so rs232 requires assignment to a file ? and PUT simply writes data to a file, and PUT does not care what is hapening to that file ? .... or PUT needs to write data when rs232 is not reading ?

cloud of questions thank you !
