Hello,
As part of a larger power cycling program I need to monitor a serial port for a phrase to indicate the system has finished (SYSTEM_READY). For some reason the serial port "looses" 10-ish bytes of data. I think that it is because the port receives the extra data between reading the number of bytes on the port and the time it actually retrieves the data and flushes the buffer. To test this I tried to write another VI just to list out what the serial port is spewing out and see if it matches the log I received from TeraTerm. It works as expected until it tries to execute the VISA Read VI. Then I get the -1073807298 error with the text "VISA Read in Serial Console.vi". I found an article that seemed pertinent but I add the buffer I/O VI and nothing changed. I'm using LabVIEW 2011 (32-bit) on a Dell Optiplex 745. The serial port is integrated into the board, and the computer has an ICH8/ICH8R Family LPC Interface Controller. Does anyone have any suggestions?
Thanks,
Simon
