o NB with the use of Override Settings, you need to ensure that the equipment you are

connecting to is setup to match the communications settings you are forcing.

CTS / DSR Always True

 CTS and DSR are incoming hardware handshaking lines. This means they receive signals

from the connected device which tell the Ethernet to Serial device when it is and isn‟t OK to

send data.

o Sometimes these signals may want to be ignored. By forcing CTS or DSR True, the

Ethernet to Serial device will ignore those signals and always send data.

o These settings are especially helpful when CTS and DSR are not physically

connected (such as in a 3 wire setup) and it is not acceptable for the data flow to stop

and start due to arbitrary variances on the unconnected signal lines.

o NB: Some ES devices do not support RTS/CTS or DTR/DSR handshaking and as a

result, “CTS Always true” or “DSR Always true“ will be enabled by default. Please

check the product datasheet for your device to see what hardware handshaking is

available.

Changing your COM label

1. If you need to change the COM label, Double click on the Port entry in Boost.LAN Manager

2. Click on the „Port Settings‟ tab and click Advanced

3. A new COM Port label can be selected from the dropdown menu. Click OK to set the new

COM Label.

4. If the COM Port number is labelled “in use”, it is either currently used by a COM Port present

on the system, or is reserved for a device which is not currently present. It is possible to

select this COM number and force the change, if you are sure it is not required by any other

device.
