In case anyone cares, I found the following in the RMS documentation, 
which I missed, when discussing the FAB$V_SQO flag.

Note
For DECnet for OpenVMS operations, this option enables file transfer 
mode for Get, Put, Read, and Write services. File transfer mode is a 
Data Access Protocol (DAP) feature that allows several records to be 
transferred in a single-network I/O operation to maximize throughput for 
single-direction, sequential access file transfer.

I took it out and I get the messages one at a time, as expected.
