If you have control of the mystery device's software, the solution is obvious: don't do baud rate detection. If you can't fix it that way, the only simple thing I can think of to try is to add a delay circuit that prevents data from getting through at all until some time after power is applied.

(More complicated possibilities abound, such as putting another custom circuit in the line that sends the @ character before the RC has a chance to foul up the baud rate.)
