HI

The AUX port has hardware flow control by default, so you will need to give the ports DTR and DCD signals at least to open them. Also the TX/RX will need to be crossed.

ah, The AUX port is generally named 'line aux' rather than one of the Async ports. Can you do a 'show line' this may show the aux port as 17 or something.
