Sorry, I am behind on my mails, due to an operation I couldn't do much of anything.
It doesn't really make sense what you are writing, because the K3/0 should never need to be placed into terminal mode
manually. Something somewhere may be wrong with the settings. If you mail my the HTML file of each RRC, I can see
if there is a mistake in one of them. Otherwise, Brandon at Elecraft may be able to see if he can figure it out.
