OtherUlise, one

two

This results from the fact that the detection of

The

example illustrates how a user would set
breakpoints in
his
device
driver
to
verif~
that
it
is
performing
the functions of
a
driver as specified in section
26.2.
The example shows EXbug 1 as the debug monitor:
=COpy #UDJTESTiNMD=DRIVER

The EXbug monitor is given control after

7.6 COpy
with EXORtape Reader
The COPY command will provide users with EXORtape ·paper
tape
readers
an
additional
device type,
Users with paper
tape readers that are similar to the EXORtape
can
also
use
the
COpy
command
without the requirement of a user-defined
device driver.
The EXORtape reader interfaces
through
a
PIA
on
the
EXORdisk
I
interface" module.
The following steps must be
followed to permit the EXORdisk
I
Interrace
Module
to
be
accessed by the COpy command.
