> The Asyn device support routines are not currently using this extended support though
Krzysztof Lazarski actually started this at an EPICS Codeathon way back in 2008, but I've never gotten it incorporated into a release. I'd like to aim to get it into the next (4-24) release. That would be a good time to make the error handling of input and output links consistent and correct.

I agree. The extended device support mechanism that allows changes to
hardware link addresses and device types at runtime also sets PACT to
mark a record for which the device support has rejected the address (it
will clear PACT if a device support accepts the record).
The Asyn device support routines are not currently using this extended
support though, so you can't change the INP/OUT field of a record that
is configured to use Asyn, or switch from another device support to an
Asyn one at run-time.
