Sorry but your whole query is pretty non-sensical...

What interface does your radio card present for connection to the host
computer? The documentation (you know that stuff that nobody seems to read
:-) for the radio card should be specific.
If it is an rs232-type serial interface, it should say something like rs232
at TTL levels, like TS describe some of their "rs232" interfaces.
They should also specify the EXACT baud rate at which they drive this
interface - you have to match this EXACT baud rate on the TS board side.
They should also say how many data bits, whether or not they use parity
etc.
If they don't give this info, then start to suspect that it is not an rs232
type interface - there are many other types of serial interface e.g. i2c,
spi and these are driven in an entirely different way.
