Flow Control 4
The WaveLAN/EC-S supports six different flow controls that you
can use to customize the incoming and outgoing data flows
between your WaveLAN/EC-S device and the host device
connected via the Serial RS-232 port.
You can use the [flow control] menu to select which flow controls
you would like the WaveLAN/EC-S to recognize or ignore.
■
To allow the WaveLAN/EC-S to recognize a specific flow
control signal, change the parameter value to “yes”.
■
To instruct the WaveLAN/EC-S to ignore a specific flow control
signal, change the parameter value to “no” (=default).
The host device can use one or more of the following incoming
flow control signals to instruct the WaveLAN/EC-S when to start/
stop sending data:
■
incoming software

.
■
rts (request to send).
■
dtr (data terminal ready).
You can set the WaveLAN/EC-S device to use one or more of the
following outgoing flow control signals whenever it wishes to
instruct the host device to start and stop sending data:
■
outgoing software.
■

dsr (data set ready).
Your WaveLAN/EC-S will typically send these signals to the host
computer whenever its buffers are full or empty again.
