Please wrap your text in <p> and your code in <c> tags so it's readable.

A few things to try:

1. Check the return value of write_settings(): $PortObj->write_settings or die "failed to write_settings";

2. Turn off handshake: $PortObj->handshake("none");

3. Check the return value of write():

my $count_out = $PortObj->write($sendData);
warn "write incomplete\n" if $count_out != length($sendData);

4. Wait a little while before closing the port - add a sleep(3); before $PortObj->close(). (Note: Although this may not be needed, a quick skim of the module's docs don't make it clear whether write() is blocking or not.)
