 All the packets that are inbound to my serial port start with 0x02 and
end with 0x03. How do I read the entire packet into a scalar?

Right now, using $loc = $ob->read(255) I can only get up to 16 bytes,
and sometimes I don't get the full 16 bytes.

My packet size will vary from 8 bytes to several hundred.

Thanks in advance for your help. And I did RTM but it didn't help.

Solved my problem by putting in:
$ob->read_char_time(0);
$ob->read_const_time(4000);

Still stuck on the write question.
