It turns out that I need a special cable to actually reach the "B" serial port
(which is the outgoing one). A great write-up about it is here:

And the cable is Sun part number X985A or 530-1869 which is going from $30-60+
depending on where you look. The pinout can be found here:

This is it, here:

Thanks to all who responded, especially Dave Gagliardi and Christopher Bernard.

Cheers,
