Many thanks for all suggestions privately and to this list. I can confirm that;
Ports have been checked with K3 utility Checked correct port in device manager on PC Did not stop after upgrading software I am using KUSB with latest drivers since arrival of K3 #191 K3 is set at 38400 baud I'm going to examine the transistor on the IO board. Apparently the plastic transistors can degrade over time on older K3's and the voltage drops under load to the RS232. Thanks to K1WHS for this suggestion. 73 & HNY!
