NAME

conc − Datakit concentrator

SYNOPSIS

ctlfd = open("rawdkdev/ctl", ORDWR);
write(ctlfd, "push conc", 9);
write(ctlfd, "config name nc0 nc1...", n);

­bind -a #Kname ­/dev dkctlfd = open("/dev/name/n/ctl", ORDWR);

DESCRIPTION

The concentrator partitions the channel space of a raw Datakit device (typically ­#i or #h) into subspaces of size nc0, nc1... Channel numbers are adjusted on all messages so that each subdevice sees a channel space starting at zero. This arrangement must agree with the switch configuration as provisioned by the local Datakit operating company.
