Have your code open the port with one baud rate, test it, if it doesn't get 
"Okay" in reponse to "Hello", then close the port and reopen with the other 
baud rate.

I have a similar case - it knows what the baud rate is, and what a response 
looks like, but not which port the device might be on - my app effectively 
does the same thing, except that instead of changing the baud rate on each 
test it changes the port.  That works fine, I would expect this would work in 
your case too.
