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

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
}

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