NAME
kmc, kdiload, kmcdump - control KMC11 input/output
processors
SYNOPSIS
/etc/kdiload [ dev [ file ] ]
/etc/kmcdump [ dev ]
DESCRIPTION
These commands control the KMC11-B microprocessors used for
Datakit protocol processing.
Kdiload resets KMC device dev, copies the microcode in file
into the KMC's memory, and starts the KMC. Dev may be a
pathname or a single character key identifying the KMC; the
default is `2'. File defaults to that specified in if a
single character key is used, otherwise.
Kmcdump stops the KMC and copies its state into files in the
working directory. Dev may be a single character key or a
pathname; the default is `2'. The KMC's memory is copied to
the file core.k.nnn, where k is the keyletter and nnn is
some number; the state of the KMC's registers and some trace
information from Unix is written to regs.k.nnn.
These commands search the file for KMC devices and microcode
files. The file contains lines of three blank-separated
fields:
single character identifying this KMC
full pathname of the KMC device file
full pathname of the microcode to be used in this KMC
The KMC with key K uses Datakit special files with names
like /dev/dk/dkK03. If there is only one KMC for Datakit,
its key is `2'. If the only KMC is the only Datakit inter-
face in a machine, its key is `2', and its special files
look like /dev/dk/dk03.

BUGS
For the moment, the only permissible keys are `0' and `2'.
The KMC and Datakit filename conventions are arcane, and
based on obsolete notions; they should be replaced.
