Hi list, hi Deon,

I suspect you have that problems because of the use of an inverted 
signal in the FIF-232 (so far I can remember) compared to the standard 
RS232.

When I'm back home, tomorrow, I'll scan the original Yaesu FIF-232 
interface manual containing the schematic diagram. Then you'll receive 
it as soon as possible.
