Anyone use the L9637 ISO 9141 Interface chip from ST?

This part seems to handle the interface from ISO 9141 to RS-232. It
doesn't provide optical isolation, but depending upon what you're
interfacing to, it may not be necessary. I'd like to put togther
something that will allow me to select an engine parameter, like say
engine speed, and have the car continually spit that variable out on
the port until I tell it to stop. I'd rather not buy an interface
cable since I want to incorporate the electronics into an external
module that will be processing the data.

The datasheet for the L9637 can be found at:

Any ideas?
