<div>one caveat I discovered when implementing smart beaconing via the serial port.... anytime you send a command via the serial port, it will "snatch" the display from you. For example, you are entering a message using the DMTF keypad and a command gets send over serial port, the message will simply exit and you loose what you were doing. It's pretty darned frustrating, so much so that I abandoned smart beaconing for the d700. Now, simply catching data from the serial port with a external processor, manipulating it and sending to the GPS would be ok... but trying to set frequecy on the display _will_ interrupt the user if he's doing something... and I could not find a way to let the external processor know that you were using the display to hold off sending data.....

<div style="DIRECTION: ltr"> The data on the DB9 serial port also seems to include data similar to what could be used to control the D7/D700 display. Wouldn't be surprised to learn it is the same data sent to the display. It apparently includes data to indicate when the A or B side squelch opens or closes (CT 0,1 etc) and may include info to control how many bars of the signal strength should be displayed when the squelch is open. When you transmit, it sends what I think is the receive frequency, offset and other unknown parameters. Need to investigate these display commands or operation reports in more detail.
<br><br>If you wanted to use the LIST n position data from the DB9 serial port to create Waypoints with APRS icons using the Garmin Protocol, you would have to find a way to route this from the DB9 serial port to the D7/D700 GPS serial port. It may be possible to do this by wiring the output of the PIC or ARM etc device to the GPS serial input. The GPS would still send Position data to the D7/D700 GPS port, but would receive Waypoint data from the "PIC" port.
<br><br>An external application on a desktop or laptop could also create the waypoints/icons using Garmin protocol and use an external device to route the data to the Garmin GPS in a somewhat similar manner. May need to ensure that only waypoint data is routed to the GPS input.
