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.
