[Elecraft] Any ideas on how to run serial (DB9) and USBserial at the same time?

[Don Wilhelm]

David,

The solution for the KX3 and KXPA100 is greatly simplified if you use 
the KX3 to KXPA100 adapter cable.
You connect the KXPA100 to the personal computer and the adapter cable 
splits out the RS-232 signalling to the KX3.  See the connections on 
page 14 of the KXPA100 manual.  The KX3USB cable connects between the 
KXPA100 and the PC.

No MAGIC BOX needed.

The PX3 does not have to be continuously connected to the computer.  For 
firmware updates, Configuration Save and Restore, you can connect a 
KX3USB cable and run the PX3 Utility for those operations (those are 
done off-line and not real-time).
