Now, that the problem with the NMEA interface of GpsMap 276C with my
autopilot is practically solved with the 3.21 upgrade, I would like
to rise again the issue about the DSC, making the following questions,
which I tried to made to Garmin, but has not received a consistent
answer:

a) As I already have the Map276C sending NMEA messages to the autopilot
and to the PC chart plotter software, and I am receiving NMEA messages
from the depth sounder, all this working fine using the Map276C COM1 at
4800 bps, would be possible to make a interface with a VHF/DSC radio
in order to use the new DSC function of Map276C?
b) Knowing that the gps allows sending NMEA messages up to 3 devices,
and I am using only 2, can I use the COM1 to send NMEA to my VHF/DSC?
c) But, as I am receiving NMEA from the depth sounder, could I mix
this info with the NMEA from my VHF radio in the COM1 to receive the
"Position Reports", assuming that my new radio has NMEA in/out?
d) If the answer is NOT, than I ask: can I use the second serial port
COM2 of GpsMap276C to make this connection?
e) But how I can do this, if the GpsMap276C does not allow me to set
BOTH serial ports to NMEA?
f) And, If I could use the 2 serial ports set to NMEA, how I can setup
the COM2 to 9600 bps, which is the speed that DSC needs, if the actual
software of GpsMap276C does not allows me to make this change?
g) Concluding: has anybody successful tested the DSC function of
GpsMap276C, including the reception of "Position Reports"?
h) If yes, could he please, explain to me how this is done?

Thanks

Pascal
