This is most likely an IRQ problem.  NA cannot share IRQs between COM 
ports.  Windows let you do it, but that is irrelevent.  Each COM port has 
to have its own IRQ.

Also, is the COM3 port address correct?  Go to the COM port setup screen in 
CONFIG - is the hex address (at the left end of the COM3 line) what you 
expect it to be?

I know this type of configuration works, I do it all the time at K8CC.  But 
you have to be sure of what the port setting are, and it can be confusing 
to figure out without yanking cards out of the machine and doing things by 
trial and error.
