The > other computer will simulate one or more disk drives which are acessible by > commands sent over the serial line. 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? 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?
