It would be helpful to know the values that $baud, $dbits, $sbits and
$parity contain .... just so we can see that they are sane :-)

I wonder if increasing the size of the read buffer enables you to collect
larger amounts of data.
----------------------------------
$PortObj->buffers(4096, 4096); # read, write
# returns current in list context
----------------------------------
Try increasing it to accommodate the larger inputs and see what happens.
That's probably not the way to fix the problem, even if it works .... but
knowing whether (or not) it works might help in finding the correct
solution.
Cheers,
Rob
