I have never heard of two start bits on async protocol.

Neither have I!

Two stop bits yes and these, when used, do play a role of providing an extra bit time of dwell between characters to permit software to get the receive data registers unloaded.

Quite so.

In fact, the stop bit is the same state as the line idle state - so it's not possible to distinguish between sending 2 stop bits, and one stop bit followed by one bit-time of idle!
