Does anyone have suggestions on how to provide NMEA data to several
"listeners" for example autohelm and radar. Here is the setup: I feed
several NMEA enabled instruments output to a laptop via a NMEA
multiplexer
then, feed the NMEA data stream to an autopilot and radar using the com
RS232 port. However I have a single com port. How do I feed both
listeners?

By connecting the TX wire from the com port to both listeners. Also, some
multiplexers provide a 'real' NMEA output, on which the data from the
laptop
is available. Such an output is capable (or at least should be) of driving
four listeners.

Take a look at this page: www.shipmodul.com/en/connections.html Fig. 6 at
the bottom shows how multiple listeners can be connected to a single
talker.
In case of your com port, forget about the Out B on the multiplexer.
