[tkined] problem: binary data and the udp send

Hello!

It seems like Tnm udp command cuts messages at zero value.

Here is my code:

set msg [binary format H2H2H2 01 00 01]
set broadcast [udp open 68]
udp send $broadcast 195.222.130.75 67 $msg

Using tcpdump I found that only first byte (01) is sent to network:

tcpdump -s 600 -x -l src 192.168.1.1 and udp port 68

17:00:23.061397 myhost.bootpc > ourrouter.bootps: [|bootp]
                         4500 001d e6bc 0000 4011 07c5 c3de 8246
                         c3de 824b 0044 0043 0009 7206 01
                                                           ^^^ there is no
00 01 here

My Tcl is 8.0.3 on Linux. Scotty is last 3.0.0 snapshot. I checked for
possible problem in "binary" command - it looks to be OK.

Any suggestions?

Tnanks in advance.
