[Elecraft] School of hard knocks

[Charles Bland]

Gang,

Why working out the details of a serial interface cable between my 
Handspring Visor and K2 (trying-out Pat K0PC logging program - 
cool! try it!) I apparently made my K2 unhappy.

I must have got across one of the wrong lines on the KIO2 
connector. As a result, I ended-up with NO output from the K2 at 
all.

Short story: I popped a pin on the main MCU and had to replace 
the MCU.

Moral of the story: When doing a serial interface, only  use pins 
1,2,3, and 5. Stay off the rest.
