He said none of the commercial external soundcards will work with 9600 bd packet. The only option is to construct a circuit, or use a 9600 baud TNC. (not too many options on that front.)

Mine is setup for the 6pin miniDin connector(the pin 4 - for 9600 bd on my radio dataport- is not connected) for my FT 847.  At this time I can only decode by connecting the 9600 pin on my radio (dataport) to a line-in to my Laptop soundcard (and not using a isolation circuit).
