Re: VISA serial communication in LV 7 application

[Mike Burnett]

I have made a new VI.  All it has in it is

VISA Configure Serial Port.vi

The only input wired is VISA resource name, which is
"ASRL2::INSTR".  The only output wired is "error out".

When I run the VI, I get a green checkmark in the
error out status and 0 for the error out code.

When I build this VI into an application and run
it on the development system, I get a red X in the
error out status and -1073807246 in the error out code.

I have a feeling that either VISA serial communication
is broken on my Windows 2000 development system or LV7.

I really need to make this work, and I have no idea
what to do.

VISA serial communication in LV 7 application

[Mike Burnett]

My development environment is Labview 7.0 running under
Windows 2000.  I have a VI that communicates via VISA
serial.  The VI works fine, and information flows back
and forth over the serial line.  When I build the VI
into an application and run it on my development
system, everything appears to work fine.  There are
no errors of any type reported.  However,
no information is communicated over the serial
line.  This is really frustrating!
