Overlay dynamic coordinates from an external source

Good morning
I capture video with a remotely operated underwater camera (ROV) and record the video with OBS on a dedicated computer. Another device records the position of the camera (coordinates) and generates a text string with the current position every second (i.e. text with LAT/LONG - XY).
I would need to put these coordinates (which update every second) as an overlay on the video (ideally in real time but I can also do this in post-processing with the coordinate list on a .txt file). The text string with the coordinates arrives on the computer with OBS via a serial connection (RS232). does anyone have any idea how I can solve this
I have searched this forum and couldn't get the answer I'm looking for... So sorry if it was already posted
many thanks
