VISA configuration serial port error

[MileP]

I have labVIEW2010 installed in Windows 7, and a USB to Serial RS232 converter for COM8.

When trying to test the serial communication, I got the error -1073807330 at VISA Configuration Serial Port VI output.

The serial port baudrate is 57600, and I followed http://digital.ni.com/public.nsf/allkb/837E900144390C8C86256E35006C6A2D when setting up other configurations.

Any suggestions?

Thank you.

By the way, I tried with hyperterminal and the COM8 works fine. Is it possible that VISA doesn't support virtual COM port?

Visa supports real and virtual com ports

Are you sure you are not asking too many characters?

try the basic serial example.

Sorry

I misinterpreted the error code. This one means that the attribute you set is not accepted by your adapter.

It could be that your adapter's driver does not correctly communicate what baudrates are supported or that 57600 is simply not supported but I don't believe that. It also could be that it should be a slightly different baudrate.

Maybe find out via hyperterminal together with NI-SPY

Sorry. It was my mistake. I tried another USB to serial port adapter and it works.
