I use one of these:

Edgeport 8. Available at the below link:

It works just great for rig control (Icom 756 Pro III),  FSK and rotor control.

  The one I have says F5U103.

  There are a number of chipsets that can do 5 bits.  I recently found  
  that the chipset in the KeySpan High Speed adapter can do 5 bits and  
  get within 0.012% of 45.4545 baud, but unfortunately the driver they  
  had supplied could not be coaxed to do 45.45 baud.

  One of the options nowadays to get 45.45 baud/5 bits, if you insist on  
  still using FSK keying, is to use Doug K4DSP's regenerator http://k4dsp.homeip.net/~doug/regenerator/ 
    to go from AFSK tones from a software modem to an FSK keying signal  
  for the rig (and it comes free with VOX PTT, also).

  (I know W9OL himself has reformed and he is using AFSK with his  
  Flex-5000A :-) :-)
