I'm using the Advanced Serial Data Logger, Enterprise version.
Sourcing data from two COM ports:  COM1 is a water quality sensor, outputs four float variables.
COM4 is data from a Garmin GPS.  The objective is to read the data streams, parse them, and then use Aggregator to combine the GPS coordinates with the water quality parameters.

Data reads in OK.
Data from both instruments parses OK.
The parsed data from COM4 is redirected to COM1 OK.
The DDE Server, when opened under COM1, shows all the parameters from both data streams.

However, I cannot seem to combine the data as Aggregator promises.  Only the data from COM1 shows up in the Aggregator, but none of the GPS variables from COM4.
