I take it your microprocessor doesn't run linux. In that case, you want it
to look like a serial bus master.
There are 3 serial bus masters that I can remember off hand: the DS9097U,
the Link and the HA5. The later 2 use a much simplified serial data stream
(simple ascii), and I think are both available in chip format for fairly
cheap. The radio part would be transparent.

(I should add that the serial port can synthesize a bus master -- the
passive adapter) but I wouldn't recommend that remotely. Code for DS9097U
emulation is available -- Maxim never considered restricting masters, only
slaves).
