comm package issue

Hi,

I am trying to invoke commands on a remote machine using comm package
in Tcllib.
I am running into an issue where the command never returns and is
blocked.

Below is the sample code.

On server (windows):

% package req comm
4.3
% comm::comm config -local 0
% comm::comm config
-port 3926 -silent 0 -encoding utf-8 -chan ::comm::comm -local 0 -
listen 1 -serial 0 -socket sock176
%


On client (windows)

% package require comm
4.4
% comm::comm config -local 0
% comm::comm connect "3926 10.155.0.101"
sock276
% comm::comm send "3926 10.155.0.101" set a 1


The send command never returns. If I do -async, then it returns but
the command is never evaluated on the remote side. Looks like its
waiting for something.

I am using latest 8.4 Tcl version and it happens whether client/server
are linux/Windows.

Any suggestions as to what I am doing wrong here. I remember vaguely
that I did once try using comm and it used to work fine on remote
machines.

Thanks.
