But how to control with the AMIGA's serial port (which software)? I put the pictures of this card below. Yes I have the external serial connector for this card: Do I connect it to the AMIGA serial connector? And how to control (which software)? Thanks for your help.
It says RS-232 so that is serial. It probably came with a short cable to connect from the external serial to the Amiga. Try hooking it up and talking to the card with a terminal program. You'll at least get output when you match the cards speed and mode correctly (example 9600 8-N-1).
