O.K., but given the proposal to change stringout support to include the trailing null I don’t see how drivers are going to avoid sending null terminators when handling a request from a stringout record.  Well I suppose drivers could always sent one byte fewer than every request but that seems even worse.

This is where I think that caput -S is now doing things incorrectly.

But it is not just caput -S.  It is medm, and dbpf in the IOC shell, etc.  I think that ship has sailed: strings in waveform records include the nil in NORD.  In fact that is what Andrew recommended in this thread for the inverse problem, i.e. reads from a driver:

asynPortDriver is now doing it that way on read operations.
