8-6-1 Remote Instructions
This Paragraph describes conversion between
the

These instructions are generated for connection with
terminal devices. Care should be taken
to
connection with
computers because
of
some echo-backs.
o Echo-back
The data entered from a terminal device
is
provided with
echo-backs from
the

o Data compare instructions
"RLV",
"RLV1"
and
"RLV2"
(Note 2)
Buffer data and transferred data are compared with each
other.
If
the
former differs from
the
latter,
the
abnormal

is
sent
back.

Notes:
1 ) Error processing
is
conducted when any format error
is
detected.
2) These instructions transfer data from a terminal
to
the
Programmer.
3) The data format
is
sent
out
when the end mark
or
terminate code
is
detected.
4) The Programmer ends
out
D1
(HEX11) and gets ready
for receiving data from an external equipment.
5) Time
