Before executing sequences.
Before executing RECV
processing.
None
Only during RECV processing.
None

processing.
None
RTS/CTS flow control: RTS sig-
nal turned ON when reception
buffer reaches 200 bytes.
Modem control: RTS signal
turned ON when data is sent
and turned OFF when send is
completed.
RTS/CTS flow control: Data
send is on standby when CTS
signal turns ON; data can be
sent when CTS signal turns
OFF.
Modem control: ON when
sequence execution is started,
OFF when completed.
Turns ON only for modem con-
trols.
During RTS/CTS flow control and modem control, the ER signal
will be controlled according to modem control operations, the RTS
signal will turn ON when sending, and the RTS/CTS flow control
operations will be used for the RTS and CTS signals for
receptions.
None

execution.
Before executing sequences.
Upon FLUSH command
execution.
(Unit Ver. 1.2 or later: Either
clear or hold before executing
sequences.)
Except when executing SEND
processing.
During sequence execution
(reception processing not
performed except during
sequence execution).
During sequence execution
(even during SEND processing)
RTS/CTS flow control: RTS sig-
nal turned ON when reception
buffer reaches approximately
2 Kbytes.
Modem control: RTS signal
turned ON when data is sent
and turned OFF when send is
completed.
RTS/CTS flow control: Data
send is on standby when CTS
signal turns ON; data can be
sent when CTS signal turns
OFF.
Modem control: ON when
sequence execution is started,
OFF when completed. Also can
be turned ON or OFF as
required during modem control
by executing OPEN to turn ON
the ER signal or by executing
CLOSE to turn OFF the ER sig-
nal in sequence steps. The ER
signal can also be controlled
across multiple steps.
The WAIT command can be
used to stop transitions between
steps to allow transitions from
the CPU Unit.
This is useful, for example, to
perform processing in the CPU
Unit after a specific step but
before executing the next step.
