I am trying to develop an app that opens comm3 connected to a GPS
device that reads activity input from the device and depending on
specific input would then need to send a string out to the GPS, which
is basically a command.
So far, either msg from Rx or Tx are being handled properly, not both
at the same time.
Grateful if sometime could advise me on how to make both the Comm
listening and sending work simultaneously, probably thru multi-
Or better, if someone could point me at some sample code which i
could start with.
