The above errors are very similar to the previous one, in that I believe they 
are caused by the PSC device support's write_ao() routine returning -1.  Both 
your dbtr() and dbpf() commands cause the record to process resulting in the 
device support being called; if write_ao() returns any non-zero value it will 
be passed back up the call tree and eventually result in they messages that 
you are seeing.  What that return value means is a question you'll have to 
ask the person who wrote the device support.
