Express Serial read/write VI errors out

[fbrandeber]

Hi,

Calling and putting in parameters in the express vi, and clicking on run, results in and immediate error with no error message, just a large negative number, which appears to come from the error out port on the initialization vi. I am new to current labview, used it over a decade ago. Hardware I am trying to access works with a windows program written for it. Windows serial port monitor indicates, as does my port breakout box, that the vi does not access the port at all.

Machine is an hp750n Pavilion. I am running the 30 day demo package of version 8.02. I am hoping that someone can push me over this bump in the road to using a current version of labview. :headbang:
