CSS(4) Kernel Interfaces Manual CSS(4)NAME
css - DEC IMP-11A LH/DH IMP interface
SYNOPSIS
/sys/conf/SYSTEM:
NCSS css_controllers # DEC/CSS IMP11-A ARPAnet IMP interface
DESCRIPTION
The css device provides a Local Host/Distant Host interface to an IMP. It is normally used when participating in the DARPA Internet. The
controller itself is not accessible to users, but instead provides the hardware support to the IMP interface described in imp(4). When
configuring, the imp(NIMP) pseudo-device is also included.
DIAGNOSTICS
css%d: not alive. The initialization routine was entered even though the device did not autoconfigure. This is indicates a system prob-
lem.
css%d: can't initialize. Insufficient UNIBUS resources existed to initialize the device. This is likely to occur when the device is run
on a buffered data path on an 11/750 and other network interfaces are also configured to use buffered data paths, or when it is configured
to use buffered data paths on an 11/730 (which has none).
css%d: imp doesn't respond, icsr=%b. The driver attempted to initialize the device, but the IMP failed to respond after 500 tries. Check
the cabling.
css%d: stray output interrupt csr=%b. An interrupt occurred when no output had previously been started.
css%d: output error, ocsr=%b icsr=%b. The device indicated a problem sending data on output.
css%d: recv error, csr=%b. The device indicated a problem receiving data on input.
css%d: bad length=%d. An input operation resulted in a data transfer of less than 0 or more than 1008 bytes of data into memory (according
to the word count register). This should never happen as the maximum size of a host-IMP message is 1008 bytes.
