What do you mean by "continuously ON-OFF"?

In other words you can say "to get 1 and 0(high and low signals) or getting suare wavw at the output of serial port"

You can do that only with the handshake signals, the data signal can not be controlled direct, it is driven by the data shift register.

In .NET's SerialPort class, see the RtsEnable and DtsEnable properties.
