Hello,
many thanks for an extremely useful package.
I observed the following issue in the example provided in the POD
documentation for the status method (line 2013):
=head2 Operating Methods
($BlockingFlags, $InBytes, $OutBytes, $LatchErrorFlags) = $PortObj->status
|| warn "could not get port status\n";
using || warn ... forces $PortObj->status to scalar context, so that only
the first element of the array on the LHS gets set (always to 4, being the
length of the status array), with the other 3 elements remaining undef.
Using'or' instead of '||' fixes this, i.e.:
=head2 Operating Methods
($BlockingFlags, $InBytes, $OutBytes, $LatchErrorFlags) = $PortObj->status
or warn "could not get port status\n";
Kind regards,
Chris
