Already had it set that way.

With the wire ends of the adapter NOT connected to anything, type on your keyboard, you should see nothing on the screen.
If you do see the character on the screen - disable the character echo in minicom ;

I couldn't find the option for disabling character echo in minicom, but in any case, nothing shows up on the screen when I type with the computer keyboard.

Now, connect the Tx and Rx leads of your adapter together -
type into the emulator, observe the characters appearing on the screen.
If they don't appear on the screen with the adapter "looped back" to itself and character echo disabled in the configuration -
Something is not right with the adapter setup, check the instructions for the adapter board.
