Easy serial port question

[Rick Nelson]

Hi all, I've got a simple problem on my hands --

I have two machines running Win NT, one has LabVIEW 5.1, the other just
has the run time engine (so it can run LabVIEW .exe files). They are
connected via a serial port, set to COM2 for both machines (good
connection verified thru HyperTerminal).

Anyway, when I run the sample VI "Labview <-> Serial", it seems to
work. But when I make it an executible, it returns "Error 37 - Device
not found". Now, I'm not *sure* it's working as just a VI because the
other computer does not have LabVIEW on it, but I don't get any errors.

.... and I am including "serpdrv" when making the .exe, but I think that
only matters for LabVIEW 3.1 and older.

Any ideas on what is going on?

I think a copy of serpdrv needs to be in the same directory as your new
executable.

Does the executable behave the same on both machines?

....if anyone else has had this problem... not only does serpdrv have to be
in the same dir, but you must append the following line to labview.ini
before compile:

serialDevices="COM1;COM2;COM3;COM4;COM5;COM6;COM7;COM8;
COM9;\\.\COM10;\\.\COM11;\\.\COM12;\\.\COM13;LPT1;LPT2;"

(all one line)

.... and then copy that .ini file to "myprogram.ini" and change the first
line from [labview] to [myprogram], and put the .ini file in the directory
as well.
