Careful with those parens. You may not realize, but that

Hi I just don't understand the perlfaq example. All I want is to capture output
of an external command's stdout and stderr. Here is what I've tried:
sub get_exit() {
my ($exit_status, $std_out, $std_err) = @_;
my %error_codes = (

We are out of contest in here.
I know how to run open3, but I don't know how to test it. Repeating

the idea is to process the STDOUT ad the STDERR.
open don't do it

Since you mention simplifying the code, do you actually
need IPC::Open3 ? In your sample code, you're only
reading process output.
If you don't need IPC::Open3 complexity, you could just
use magic open to read output :
sub shell_run
{
print "";

I'm having a more or less complicated code, that was simplified to this.

Basically I'm suppose to be able to change the cameras
which are displayed on the webpage. Right now I can
change the cameras displayed on the webpage by
accessing Tip and typing in a command like '@01' (any
value through @01-@16) also you can type in '@22' (any

What's giving you this error message? If you're

I'm not sure where you got this idea. IPC::
As a last ditch effort to get this serial device to
write I found a Perl module called "IPC::Open3" it
seems to have the ability to write to a serial device.
Does any body have any experience with it? I read the
documentation on CPAN.org's site numerous times but
kept on asking my
