Looks good.  If you're getting data, even gibberish, you're probably
using a good cable.  There is the off chance that the previous user of
this system set the baud rate to something other than 9600.  I'd also
set the xmit/recv pace (also known as handshake) to none, at first.

Try stepping up the baud rate, one step at a time, 19200, then 38400.  I
doubt it would be set faster than that.  Possibly slower too, could be
2400.
