<Does the DL11 port have an interrupt that is driven when data is
<received, or do processes have to constantly poll it to receive data?

Yes or you can poll.

<Is the information stored on a PDP-11 disk in 8 or 9 bit words?  How
<many bits per word are transmitted/received by the DL11?

Disks are 8bit (2 8bit, 1 word = 16bits) and the DL can be set to send 
7 or 8 bits and with or with out parity.
