Maybe you could use fscommand to call a function that sets a state in your page, then call another function to check the state every so many milliseconds from the other flash.

search for "LocalConnection" in the flash help. there is a good example

// Code in the receiving SWF file
this.createTextField("result_txt", 1, 10, 10, 100, 22);
result_txt.border = true;
var receiving_lc:LocalConnection = new LocalConnection();
receiving_lc.methodToExecute = function(param1:Number, param2:Number) {
  result_txt.text = param1+param2;
};
receiving_lc.connect("lc_name");

// Code in the sending SWF file
var sending_lc:LocalConnection = new LocalConnection();
sending_lc.send("lc_name", "methodToExecute", 5, 7);
