[Elecraft] [K3] Built in USB interface for K3

[Phil Hystad]

But, how is this any different then using an external RS232 to USB converter cable or whatever.

My own desire is to get rid of the funky antiquated RS232 protocol that is troubled by line speed issues, signaling lines that aren't needed and so on.  USB offers so much more but you lose that when you have to filter it out by converting to an RS232 device no matter where you put it.
