Display Console Operation, Mod 158 (cont'd)
Error Message Response
If
a console hardware error occurs,
the
following message may appear on the screen:
IEE170E
RETRYABLE
ERROR. RECENT ACTION
MAY
NEED TO
BE
REPEATED. IEE170E PRESS THE CANCEL
KEY
TO RESTORE THE
SCREEN.
Perform
the
indicated action (press
the
CANCEL key). This should restore
the
screen,
including messages displayed
in
the message area,
the
PFK display line,
the
instruction
line, and
the
warning line.
Note: If you
do
not
press
the
CANCEL key,
the
system will automatically rewrite
the
screen (same effect as CANCEL) after
about
30
seconds have elapsed.
If
a console
hardware error results from keyboard input,
the
system
will
always regard it as a
temporary error. If it becomes apparent
to
you
that
the
error
is
permanent, switch
control
to
an alternate console (procedures for console switch are
describ~d
in
the
Operator's Library Reference publication for
the
system you are using.)
Blank Screen Response
If
the
console screen goes blank, a console switch
is
probably taking place. The follow·
ing message should appear
on
the new console:
IEE1431 OLD=xxx, NEW=xxx, VALDCMD=xx
IEE1431 ROUTCDE=i<x[,xx] T=x
H=x
In
the
actual message,
the
appropriate values will appear
in
place
of
the
x's.
Use
the
alternate console
to
continue operating
the
system, and have
the
old console checked
for
the
source
of
the
error.
NOTE:
It
is
normal for
the
screen
to
go
blank for a few seconds
if
the
back·tab key
is
pressed when the cursor
is
not
in
the
entry area.
Locked Keyboard Response
Sometimes
the
system
is
unable
to
blank
the
screen.
If
you find
that
you
cannot
enter
commands through a console
that
appears normal,
try
to
restore
the
screen by per·
forming a CANCEL action.
If a console switch has taken place, operate
the
system from
the
alternate console, and
have
the
old console examined for
the
source
of
the error.
NOTE: I nhibited input, with
or
without
keyboard locking, may also occur when
the
system goes into an ABEN D
wait
state
or
when a problem occurs
in
the
message
handling portion
of
the control program. Check the procedures described for console
inactivity under "System Errors."
