Eh. Really? OK, well, I would advise against this method, but I was determined to get it working using my original unpack version.. so here goes

sub str_to_hex { my $str = shift; my @h; for my $s (split(/(....)/, unpack("H*", $str))) { if ($s ne '') { if (length($s) < 4) { $s = ("0" x (4 - int(length($s)))) . $s; } push @h, "0x" . $s; } } push @h, "0x0000" while @h < 4; return @h; } for (str_to_hex("COM7:")) { print $_ . "\n"; }

This outputs
0x434f
0x4d37
0x003a
0x0000
