Bill,

OK. I'm not certain I understand, but pqing(1) looks like it might be the 
solution if you positively must use serial transmission.

Yes, you should execute the pqing(1) process via an EXEC entry in the LDM 
configuration-file. This will ensure that the pqing(1) process is a member of 
the LDM server's process-group and, consequently, the upstream LDM processes 
that are also members of the group will receive SIGCONT signals whenever the 
pqing(1) process inserts a data-product -- telling them there's a new 
data-product to consider and making the transmission of the data as low latency 
as possible.
