opening /dev/sequencer, in perl.

[Etienne Grossmann]

  Hello, I have been trying to open /dev/sequencer for writing : In C,
I do :

    fd = open("/dev/sequencer", O_WRONLY))

and the filehandle can be manipulated (carefully) to produce sound. In
perl, I have tried :

try1:
                open(FD,">/dev/sequencer") or die "NOPE\n"; 
                print FD "";

try2:
          use IO::File; 
                $fh = new IO::File "/dev/sequencer", O_WRONLY; 
                print "NOPE\n" unless defined($fh);

try3:
    use Fcntl; 
                sysopen(FD,"/dev/sequencer",O_WRONLY) ; 
                print FD "" ;


  but none of them work. 


  Would anyone have an explanation to my troubles?
