                     30: .I acc
                     31: device provides a Local Host/Distant Host
                     32: interface to an IMP.  It is normally used when participating
                     33: in the DARPA Internet.  The controller itself is not accessible
                     34: to users, but instead provides the hardware support to the IMP
                     35: interface described in
                     36: .IR imp (4).
                     37: When configuring, the 
                     38: .I imp
                     39: pseudo-device must also be included.

                     41: .BR "acc%d: not alive" .
                     42: The initialization routine was entered even though the device
                     43: did not autoconfigure.  This indicates a system problem.
                     44: .PP
                     45: .BR "acc%d: can't initialize" .
                     46: Insufficient UNIBUS resources existed to initialize the device.
                     47: This is likely to occur when the device is run on a buffered
                     48: data path on an 11/750 and other network interfaces are also
                     49: configured to use buffered data paths, or when it is configured
                     50: to use buffered data paths on an 11/730 (which has none).
                     51: .PP
                     52: .BR "acc%d: imp doesn't respond, icsr=%b" .
                     53: The driver attempted to initialize the device, but the IMP
                     54: failed to respond after 500 tries.  Check the cabling.
                     55: .PP
                     56: .BR "acc%d: stray xmit interrupt, csr=%b" .
                     57: An interrupt occurred when no output had previously been started. 
                     58: .PP

                     63: The device indicated a problem receiving data on input.

                     66: An input operation resulted in a data transfer of less than

                     68: data into memory (according to the word count register).
                     69: This should never happen as the maximum size of a host-IMP
                     70: message is 1008 bytes.
