perform
the
same
function
as
the
BASIC
PR#
and
IN#
commands,
respectively.
T
he
syntax
for
the
printer

is
as
follow
s:
*# CTRL-P
#represents
the
slot
number
of
t
he
peripheral
device
to
which
data
is
to
be sent.
For

to
3FF
to
the
peripheral
device
with
its card
in
slot

*300.3FF
The
preceding
command
causes
subsequent
monitor

in
slot
#1

be
accepted
from
the
device
whose
controller
card
is

Data can again
be
accepted
from
the
keyboard

executing
the
following
command.
