Try this query function:

Code:

function query(req, out)   if not sock then     return   end   sock:send(req .. '\r\n')   local res, err = sock:receive()   if not res then     return close(err)   end   local pos = res:find('~')   if not pos then     return close('invalid reply1 ' .. res)   end   res = res:sub(pos)   if res:sub(2, #req) ~= req:sub(2) then     return close('invalid reply2 ' .. res)   end   local val = res:sub(#req + 2)   log('response', req, out, val)   val = tonumber(val)   if val then     grp.checkupdate(out, val)   end end

Now this is working great, but still sometimes are status update is immediate, but  many times it is taking significant amount of time to update.
