Function
The function of these words is
defined by the Inner Board.
The flag corresponding to the speci-
fied FAL number will be turned ON
when FAL(006) is executed. Bits
A36001 to A39115 correspond to
FAL numbers 001 to 511.
The flag will be turned OFF when
the error is cleared.
ON when an error has occurred at
the RS-232C port. (Not valid in
peripheral bus mode or NT Link
mode.)
ON when the RS-232C port is able
to send data in no-protocol mode.
ON when the RS-232C port has
completed the reception in no-proto-
col mode.
When the number of bytes was
specified: ON when the specified
number of bytes is received.
When the end code was specified:
ON when the end code is received
or 256 bytes are received.
ON when a data overflow occurred
during reception through the RS-
232C port in no-protocol mode.
When the number of bytes was
specified: ON when more data is
received after the reception was
completed but before RXD(235) was
executed.
When the end code was specified:
ON when more data is received after
the end code was received but
before RXD(235) was executed.
ON when 257 bytes are received
before the end code.
ON when a communications error
has occurred at the peripheral port.
(Not valid in peripheral bus mode or
NT Link mode.)
The corresponding bit will be ON
when the RS-232C port is communi-
cating with a PT in NT link mode.
Bits 0 to 7 correspond to units 0 to 7.
The corresponding bit will be ON for
the PT that has priority when the
RS-232C port is communicating in
NT link mode.
Bits 0 to 7 correspond to units 0 to 7.
Indicates (in binary) the number of
bytes of data received when the RS-
232C port is in no-protocol mode.
