[Elecraft] Mac utility with K3S Puts K3S in TX mode!

[Guy Olinger K2AV]

Consider the FTDI driver as a program and part of the computer.

If CONFIG:PTT-KEY is *not* OFF-OFF in the K3, then you have to exert
knowledgeable control over the DTR/RTS states from the computer.
Otherwise, turn them off so you don't get surprised.

If PTT-KEY *is* OFF-OFF in the K3, then those states, from whatever
source outside the K3, are ignored, period.
