Monitoring DTR RTS CTS

[gfhf]

Hello,

I'using Labview 5.1.1

I just want to monitor DTR RTS CTS states of my COM port.

I think it's basic, I know Google is my friend but i've spend too much
time trying tips that do not work.


What is the easiest way to perform the task according to you ?

thank you.

Are you using VISA or the older serial functions? With VISA, you can do it with a VISA property node (Modem Line Settings). In your old version of LabVIEW the property node may have been called something (attribute nodes?). The other serial driver has a function called serial line ctrl.vi and it's in vi.lib>platform>_sersup.llb.
