how to control rs232 signals (DTR, DSR, etc.)

[Vanessa]

my device is in sleep mode by default. i need to activate its DTR
every 20 minutes to wake the device up, poll for DSR and establish a
connection for at least 1 minute with another device of the same type.
any pointers on how to go about this? i'm pretty new in using labview.
my version is 6.0.2. thanks a lot!

Hi Vanessa,

I recommend you to read this Knowledgebase and to have a look into this Example.

I've seen too late that you're using LV 6.0.2. I've attached the example so that you can open it.

There are VISA properties to do that.

Functions palette --> Instrument I/O --> VISA --> VISA Advanced --> Property node --> Click on Property --> Modem Line Settings
