details of error messages, see (3).
(a.6.2)
RTS
+-+ CTS
Tests
the
RTS·CTS circuit.
By
turning ON/OFF
the
RTS signal,
the
system reads these
states by means of
the
CTS and tests
them.
If
the
system
detects an error,
it
displays
the
following message.
RTS-CTS error.
(a.6.3) DTR
<-7
DSR
Test
the
DRT-DSR circuit.
By
turning ON/OFF
the
DTR signal,
the
system reads these
states
by means
of
the
DSR
and
tests
them.
If
the
system
detects an error,
it
displays
the
following message.
DTR-DSR error.
(a.6.4)
PORT
Tests
the
CI
and
CD
circuits.
By
turning
ON/OFF
the
DTR signal,
the
system reads these
states by means
of
the
CI
and
CD
and
tests them. If
the
system detects
an
error,
it
displays
the
following message.
Port error.
(2.2) Character
transport
test
(a) Test
This
test
is
conducted
by
specifying
the
transmission rate
and entering any characters
to
be transferred.
The data length, stop
bit, and parity
type
are set
to
8 bits,
1
bit, and
odd,
respectively.

(a.3) Execution and Completion of
Test
After starting
the
test,
the
system sequentially displays
characters being transferred. Upon
completion
of
the
test,
the
system displays
the
following message.

conducting
the
test.
For example, if
the
system detects
that

the
following message.

(3) Error Message
Since
the
following error messages are
the
same as those
of
the
8250,
it
is
advisable
to
also refer
to
them.
•
SD
timeout
Represents
that
a response
to
send
data
could
not
be
detected
in
the
specified period.
•
RD
timeout
Represents
that
an
interrupt
of
receive
data
in
response
to
send data could
not
be
detected
in
the
specified
period_
• TSreg
not
empty
The
transmitter
shift register was
not
empty.
• Overrun error
The
510
received 4 or more characters because the CPU
retrieved receive data with a delay.
In
other
words,
the
system received characters while
all
RX
buffers became
full.
• Framing error
Represents
that
the
system
detected
"0"
in
a
stop
bit.
• Parity
error
Represents
that
the
system
detected
a
parity
error.
• Compare error
Represents
that
the
transmit
data
did
not
accord
with
the
receive data.
• RTS-CTS error
Represents
that
this
control
line was
not
properly con-
nected.
• DTR-DSR error
Represents
that
this control line was
not
properly
connected.
