I've only used Device::SerialPort under Linux, but, your stated data format looks funny. 1 start bit is ok. 1 stop bit is ok. 8 data bits dictates no parity, not odd parity. Serial data bytes are 8 bits, not 11.
Sample code:
# Perl Polling Test
# Title: Perl to chipKIT Serial Poll Test
# Author: James M. Lynes, Jr.
# Version: 1.0
# Creation Date: June 10, 2012
# Modification Date: June 10, 2012
use strict;
use warnings;
# Initialize the serial port - creates the serial port object $Arduino
use Device::SerialPort::Arduino;
my $Arduino = Device::SerialPort::Arduino->new(
port => '/dev/ttyUSB0',
baudrate => 9600,
databits => 8,
parity => 'none',
);
while(1) {
$Arduino->communicate('P'); # Send a poll
print ($Arduino->receive(), "\n"); # Print poll respons
+e
sleep(1); # Delay until next p
+oll
}
package Device::SerialPort::Arduino;
use strict;
use warnings;
use Time::HiRes;
use Carp;
use Device::SerialPort;
use vars qw($VERSION);
our $VERSION = '0.07';
sub new {
my $class = shift;
my $self = bless {}, $class;
my %init = @_;
# Sets many parameters for Device::SerialPort usage
$self->{'port'} = $init{'port'};
$self->{'baudrate'} = $init{'baudrate'};
$self->{'databits'} = $init{'databits'};
$self->{'parity'} = $init{'parity'};
$self->{'stopbits'} = $init{'stopbits'};
$self->initialize();
return $self;
}
sub initialize {
my $self = shift;
$self->{'DSP'} = Device::SerialPort->new( $self->{'port'} )
or croak "Can't open " . $self->{'port'} . " - $!\n";

There's never enough time to do it right, but always enough time to do it over...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
