[tkined] binary data and the udp extensions

I am having trouble transmitting binary data containing null bytes
over a udp channel created using the udp extensions of the Tnm package.
I have no trouble receiving binary data. If for example I receive 4
zero bytes
it comes back encoded like:

\x00\x00\x00\x00

But if I try to transmit the same string:

udp send udp1 \x00\x00\x00\x00

The receiver receives a zero length message.

I've also tried using binary strings:

set msg [binary format cccc 0 0 0 0]
udp send udp1 $msg

This also results in the receiver receiving a zero length message.

So how can I tranmit a udp message that conains null bytes?
