In which case a possible solution for a bidirectional record
(without custom record types but with custom device support) is:

record A : input record with custom dev sup, scan PASSIVE
record B : periodically scanned record, with FLNK to A

within A's read_xxx device support function:
     if PUTF true then
	grab VAL and write to hardware
     else
	read from hardware and write to VAL

This writes on demand from the CA client and reads periodically.

Marty,

  I am somewhat confused by your answer to Peregrine. I had thought the PUTF
field of a record, which is described in the "Record Reference Manual" as
"Did dbPutField cause the current record processing", is exactly what
Peregrine is looking for.
