serial port error code

[Smith]

Hi;
I'm using Labview 7.1, I used the example code "Basic serial Write and read.vi", and I set up like this : baudrate 9600, 8 bit data, 1 bit stop, 1 bit start, no parity, no flow control, visa resource name COM1, but it couldn't run, and this error dialogue appeared : "Error-1073807202 occured at Property node in VISA configure serial port(inst).vi->basic serial write and read.vi".
I checked this error code in help but i still couldn't understand and solve this problem.Can anybody explain it to  me?

regards
Smith

Hi Smith:

This sounds like a VISA problem.  What version of VISA do you have?  VISA 3.4.1 is the lastest version and can be obtained at ni.com.  Try upgrading VISA and let me know if this helps.

Hi;
Yeah, you were right, I downloaded the NI serial 1.8, and installed it. After that, I ran that program again, and  the error dialogue didn't appear anymore. And I used the software Portmon to monitor the serial port, it gave out the correct result.
Thank you very much.

Smith
