How do I suppress RTS?

[Greg_Sykora]

Using Windows2000, Labview 6.1, serial driver V1.45:

I need to interface with a low noise amplifier which uses asserted DTR(+) and suppressed RTS(-) to power an isolated RS-232 interface. With no handshake enabled, your serial initilize VI asserts RTS when asserting DTR.
The control I need is achieved in BASIC as:
10 OPEN "COM1:9600,N,8,1,RS,...
How do I achieve this in Labview?

Hello-

The control lines can be modified by a VISA Property Node. The control lines are in Properties>>Modem Line Settings. It might be necessary to right-click on the node and click "change to write".
