What you could do is to unplug the cable from the radio and connect the TX and RX pins together. (I don't know what the cable is so I don't know which pins this or how easy it would be to do.)
Once you do that any data you manage to send to the serial port will come straight back again, so you can test that the link is working, and it works at any baud rate.
The Yaesu cable does this internally, so no modification necessary.
