Good morning Salva,


I think you lead us to the correct track... :-)


open OUT, ">", "./trace.out";
my $line =0;
foreach (@cmdout) {
    $line++;
    my $bytes = print  $line.": ".$_;
    print OUT "$line: bytes: $bytes, err: $! \n";
}
close(OUT);

IF everything is fine trace looks like this for all lines:
...
1880: bytes: 1, err: Inappropriate ioctl for device 
1881: bytes: 1, err: Inappropriate ioctl for device 
1882: bytes: 1, err: Inappropriate ioctl for device 
1883: bytes: 1, err: Inappropriate ioctl for device 
1884: bytes: 1, err: Inappropriate ioctl for device 
...

IF it starts to fail:
...
1891: bytes: 1, err: Inappropriate ioctl for device 
1892: bytes: 1, err: Inappropriate ioctl for device 
1893: bytes: , err: Resource temporarily unavailable
