[Kenwood] Programming TM-732 with a computer?

[ken.d.brown at hawaiiantel.net]

I have been using RT Systems cable and software to program channels in 
my TM-281. I like the ability to type in frequencies using a keyboard, 
or even cut and past from published repeater frequency lists online. It 
is much easier than doing it from the front panel controls on the radio. 
I suppose I could use the free software Kenwood has available. I chose 
RT systems because their USB to radio adaptor cable was easier to get 
than getting one from Kenwood. I would like to have a similar capability 
to program my TM-732. I see no software package available from Kenwood 
or RT Systems for the TM-732. Since there are ways to "clone" TM-732 
radios there is definitely an ability to program the radio through the 
microphone jack, if only I had the right interface and software. Does 
anyone know whether such things exist?
