I've been trying to talk to a scrolling LED display via the serial port using WIN32::SerialPort with varying degrees of success. Problem is I can't quite tell why/when/what.

first I tried: 

use Win32::SerialPort qw( :STAT 0.19 );
my $PortObj = new Win32::SerialPort ("COM1") || die "Can't open COM1: 
+$^E\n";
$PortObj->baudrate(9600);
$PortObj->parity("none");
$PortObj->databits(8);
$PortObj->stopbits(1);

$PortObj->write ("feed me");

$PortObj->close || die;
undef $PortObj;

[download]
which worked once or twice.
then I omitted setting any params which worked fine for a whole evening, now nothing works.

SerialPort seems to pick up the settings on its own with little trouble, and a light comes on on the device whenever I try and talk to it, it's just failing to write.

any thoughts?
