NMEA, unless I'm mistaken, is entirely TXD from the GPS to RXD at the
computer. The computer end ought to be high impedance on that pin, so
you ought to be able to make up a special-purpose cable connecting just
GND to GND, and GPS NMEA TXD to computer RXD, and probably to 2, 3, or
more computers' RXDs.
What would NOT work would be any kind of combining of multiple
computers' TXDs into GPS RXD. but in this case you shouldn't need
"Nosey" Nick Waterman, VA3NNW/G7RZQ, K2 #5209.
