No I'm not adminstrator. I'm a newcomer to LabVIEW. I'm learning LabVIEW from LV Basic I CD. There's a exercise about serial communication but there are no demo for it. I used the example Basic Serial Write and Read.vi but got
Error -1073807246 occurred at Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->Basic Serial Write and Read.vi
VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it.
When I tried HyperTerminal I did see echo typed character. I don't know NISpay.
Setting I used:
data bits: 8
stop bits: 1
flow control: hardware

Thanks for your suggestion. The loopback test was working fine(I saw what I typed) from HyperTerminal by inserting the unmodified end of the cable into the serial port and the other cable end have the RX/TX pins shorted using paper clip. Also the COM1 listed under MAX-Devices and Interfaces-Ports.
I opened COM1 VISA Test Panel->Basic I/O->Write, Buffer showed *IDN?\n. Execute returned Return Count: 6, Return Status: 0.
Clicked on Read showed Count: 1024 and Execute showed Return Count: 0 and Return Status: xBFFF0015.
Here I attached the NI-SPY result. Thanks
