WaveLAN/EC-S User’s Guide
NOTE:
Most devices today are designed to allow RTS flow control
in the computer’s direction. However if the host device that
will be connected to your WaveLAN/EC-S is rather old,
you may need to verify if this device does support bi-
directional RTS/CTS control.
If it does not support bi-directional RTS/CTS control, the
device will probably expect the modem to send data at any
time. However if the WaveLAN/EC-S device would not do
so (for example waiting for a CTS) subsequent data
frames might get lost.
To emulate the “old-style” RTS/CTS behavior you may
need to use configure the flow control slightly different:
■
Set the RTS parameter to “
no
”.
■
Set the CTS parameter to “
rts
”.
Doing so, the WaveLAN/EC-S will:
■
Always forward data received at its WaveLAN
interface directly to the host device.
■
Check the Serial RS-232 port for incoming “Request
To Send” signals and respond with “Clear To Send”
whenever it is ready to receive data.

This section defines control over digital inputs and outputs of the
WaveLAN/EC-S, separately from the data lines described in the
previous section “Flow Control” on page 4-31.
Using the controls in this section enables you to send digital data
from one WaveLAN/EC-S to another without interpretation by the
WaveLAN/EC-S device itself. Like the flow control signals
