serial connection

[Alvarion_Israel]

    Hello,

I have a problem with the serial connection, i have a device that will work only with speed 128K, the problem is that labview will not communicate with this device even though other 3rd party terminals  will work with it  without no problem.

Does anyone have an idea?

If it works with something like Hyperterminal but not LabVIEW, then you have probably written the LabVIEW program or using one of the shipping examples incorrectly. Are you sending the correct termination character (i.e. CR\LF) in the correct format? Do you get any error messages or codes? If so, what are they? If you've written a program, post what you have. If you are using an example, which one?

    The problem is that i cant change the rate to 128k...

Not all serial interfaces support this speed. Serial Baud Rates Supported By NI-VISA

Check the error out connector of VISA Configure Serial Port to see if it reports something like my computer does:

Error -1073807330 occurred at Property Node (arg 2) in VISA Configure Serial Port (Instr).vi->Untitled 5
