Hi, Thank you very much, after reinstall Measurement & Automation driver, it solve the error -1073807202. This Advanced Serial Write and Read vi working fine. I had another problem. I try to use the Advanced Serial Write and Read subvi in new blank vi (Try_Serial.vi). When i simulate using lookback test, try type something in the 'string to write' but it wouldn't display back on the 'read string' Try_Serial.vi. It just display on Advanced Serial Write and Read(M).vi. It couln't pass out the string. I would like to know why the Try_Serial.vi can't display out the string while i type something in string to write box? How to solve this problem? Thank for advice.

Hi, May i know how the LabView8.2 can be interface with uC via RS232? I had tried this "Advanced Serial Write and Read.vi" LabView itself sample. When i run this sample, it will comeout a message illustrate the error: "Error-1073807202 occurred at Property Node in VISA Configure Serial Port (Instr).vi->Advanced Serial Write and Read.vi...." I reallize the error is come out from Configure Port vi error out! I had tried loopback test. I'm using RS-232 cable. I short pins 2 and 3. In hyperterminal it work but the Advanced Serial Write and Read.vi couldn't. Please anyone can help me? Thank you.
