Yes:

read EP, $in, 2; $rec_len = unpack ("S>", $in);

But whether that is the right output will depend upon what you got sent.

This would also produce the same output on either type of machine:

read EP, $in, 2; $rec_len = unpack ("S<", $in);

But which of those would produce the correct output, depend entirely on whether the data was packed in little or big-endian order to start with.

And that cannot be determined by the receiver; it can only be assumed.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
