Finding out the baud-rate is just trying out different rates, there is
no rate negotiation or similar. Usually, it's 9600, 19200 or 38400, very
seldomly anything else. 
Since the Cisco box works the connection should be ok, minicom should be
ok, the computer should be ok. Remains the radio device?!
