I think you can only do up/downloads, not any PC control with the R3. I would like to be proven wrong :.>>
Anyway, our Wiki shows that there are only 2 packages that work with the R3 -
tk3 from Bob Parnass, and ARC3 from
BuTel However, if you have the new Vista OS, it appears ARC3 is not compatible with it (per the website)
