Is the USB-RS232 adapter known to work? Several years back I had a no-name adapter. Couldn't get it to work. Found out it had a fake Prolific chip in it. No wonder it had such an attractive price.
Try looping it back to itself and see if it works before you go too far down a rabbit hole. Possible complications with modem control lines are beyond my Linux experience.
