The LM465 is only a receiver - there's no provision for it
to transmit its status.

The X10 LM14A (X10Pro PLM21) will respond with a Status_On or
Status_Off signal when it receives a Status_Request.  It will
also respond with an Extended_Status_Ack when it receives an
Extended_Status_Request.  The data byte in the Extended_Status_Ack
indicates the brightness level (0-62) and whether the bulb is
functional.  See http://software.x10.com/pub/manuals/xtdcode.pdf

Two-way lamp modules from Smarthome generally respond to a Status
Request with the brightness level (1-32) encoded in an X10 Preset
command (functions 0x0A or 0x0B) or Off.

(Both the X10 and Smarthome two-way status responses require some
minor bit-twiddling to extract the brightness levels.)
