exec tethereal in TCL with options -omtp3.itu_pc_structure:3-8-3

Hi If someone can help. I am calling "exec tethereal" in TCL WISH to
decode a Packet. e.g. /tmp/tmp.cap file is cap file with ITU Release
Complete Message (RLC) and following in the hexdump.

00000000h: A1 B2 C3 D4 00 02 00 04 00 00 00 00 00 00 00 00 ;
00000010h: FF FF FF FF 00 00 00 8D 00 00 00 00 00 00 00 00 ;
00000020h: 00 00 00 09 00 00 00 09 05 7F FB BD 8F 28 01 10 ;
00000030h: 00

I am Trying to use the -omtp3.itu_pc_structure:3-8-3 option to show the
OPC & DPC in 3-8-3 format. NOW THIS WORKS GREAT WHEN I CALL THE
FOLLOWING COMMAND FROM THE COMMAND LINE PROMPT.

########################################################################
bash2.03$: exec tethereal -r /tmp/tmp.cap -V -x -omtp3.standard:ITU

HOWEVER WHEN I CALL THE SAME COMMAND IN TCL WISH - IT DOESN'T SHOW THE
OPC & DPC in 3-8-3 format. But Show the Unstructured.
