PilotinControl:

Can you give a bit more detail about the error message and/or the changes you made to the code?

    Exact Error: Time::HiRes::alarm(): unimplemented in this platform at line 87.
[reply]

      PilotinControl:

      I see, I didn't expect that Time::HiRes was going to vary between platforms. It was just a toy thing anyway. Just remove the "use Time::HiRes" line, and change the setup_serial_interface subroutine to:

      sub setup_serial_interface {
    #my $seconds_per_transmission = 0.567;
    my $seconds_per_transmission = 1;

    $SIG{ALRM} = sub {
        push @serial_data, rand;
        alarm $seconds_per_transmission;
    };

    # First packet of data should occur in a couple seconds
    #alarm 2.5;
    alarm 3;
}

      and it should work just fine for you. (I just made those changes to my local copy and tried it out, it still works here, and shouldn't give you the error you reported.)

      The Time::HiRes was included simply so I could use fractional seconds for the alerts, it wasn't really important.

    That's the point... I made no changes to the code....copied and pasted the code into notepad....saved it as a perl file...opened in Perl ran the code and got the error
