[Elecraft] K2/100 with N1MM Contest Logger

[Ray Spreadbury]

Hi Don
Thanks for the response.
You may well be right, I bought the adaptor off Ebay and it came from Hong
Kong, I will look for one with the FTDI chip set. Thank you also for the
other settings. I did make the special cable which I connected to the K2 and
the other end of the cable terminates in the Serial/USB adaptor and into the
laptop.

  Ray,

I see you are using a laptop, and I presume you have a USB to serial 
adapter that you are using.
I suspect that adapter is the problem.  Many of them do not like to run 
well at the slow rate used by the K2.  I cannot use my Prolific adapter 
at that rate, it fails exactly as you describe.

I would try several adapters before giving up.  I have reports that the 
ones with the FTDI chip are better, but I cannot confirm that.

Either 1 or 2 stop bits should work, 8 data bits, 4800 baud, no handshaking.
DTR and RTS do not matter to the K2 because there are no wires in the 
cable for those signals.
You must have the special cable connected to the K2 - connecting the 
serial adapter directly to the K2 can cause damage.
