[Elecraft] Re: K2 - KIO2 stop bit oddity - Solved

[Joe Planisky]

Well, I now know what's causing the problem.  It seems the culprit is  
my USB-to-serial adapter (a Tripp-Lite U209-000-R).  I managed to get  
my old PC (with real RS-232 serial port hardware) running well enough  
to try it there and everything worked perfectly with both 1 and 2 stop  
bits.  The KIO2 seems fine.

Thanks to all who replied.
