[RTTY] interface cable for FSK?

[tad danley]

I want to run FSK with my IC-756 ProII and WriteLog and have heard from 
several people that I should use my serial port for this instead of a 
USB port.  Does anyone sell a prefabricated cable to go from the ACC1 
connector (8 pin DIN) on the 756 to the DB-9 serial port?  Is there a 
better way to do this?

Thanks in advance and 73,
