this may sound like a stupid question but I need (2) devices for a link, correct?

or can I have (1) rs232 device at the "send" end (I don't need bidirectional) and just an internet connection (and the appropriate software) at the receive pc?

thinking maybe on the receive end the software will write to the serial port internally or something without the need for another module?

obviously, I have no experience with these.

thanks
