2) Information necessary for
link-level and NetIPC logging.
3) Information required to
connect terminals and printers to
the system through one or more
DTC.
The only file name that the
system recognizes as the
configuration file is
NMCONFIG.PUB.SYS.
control-X echo Three
exclamation marks (!!!) output
to the terminal screen when the
cancel character (normally
[CTRL]-X) is entered.
control-Y trap User-written
procedure to which control is
passedwhenthesubsystembreak
character (normally
[CTRL]-Y) is
entered during execution of a
program with subsystem break
enabled.
cross-validate The process of
assuring that information
contained in two locations is
consistent where it is imperative
that it be consistent. For example,
an automatic cross-validation
occurs when you enter SYSGEN
to assure that information
contained in NMCONFIG.PUB.SYS
agrees with system configuration

D bit Delivery confirmation bit.
Used in the X.25 protocol, the
setting of the D bit in DATA
packets indicates whether
delivery acknowledgment of the
packet is required from the local
DCE or from the remote DTE. It
therefore allows the choice
between local and end-to-end
acknowledgment.
DCE Data circuit-terminating
equipment. The interfacing
equipment required in order to
interface to data terminal
equipment (DTE) and its
