[Elecraft] K2 interface with steppIR

[Jack Berry]

I had a similar problem with K3 and SteppIR SDA-100 controller. Experimenting 
with the order may solve the problem, it's worth a try.
I found that the how I added the devices, the order apparently made a 
difference. Try a fresh start the computer on, next turn on the radio and 
finally the SteppIR controller. That worked for me but I have not had the 
problem repeat so it may have been just a temporary software issue.

I  built my serial cable for the K2 to talk to my SteppIR controller from  the 
Elecraft manual. Works just fine. It also talks to my computer for  HRD, N1MM 
etc. So I decided to work on having the two interfaces work  together like they 
did with my IC 746 Pro.  However, building a Y cable  doesn't seem to be working 
out the way I want!  Each device works fine  when I have it plugged into the Y 
cable by itself but when I plug in  both at the same time, One or the other will 
freeze up.  I am simply  using pins 2, 3 and 5 from the K2 serial port wired 
straight through to  the female DB 9s at the device end and have 7 and 8 
jumpered at the  external device end.  What am I doing wrong?

My KPA500 arrives on Monday so I'd like to get this resolved before my next 
project!
