Property Value
Type:
System..::.Boolean
true if the port is in a break state; otherwise, false.
| Exception | Condition |
|---|
| IOException | The port is in an invalid state. - or - An attempt to set the state of the underlying port failed. For example, the parameters passed from this SerialPort object were invalid. |
| InvalidOperationException | The stream is closed. This can occur because the Open method has not been called or the Close method has been called. |
The break signal state occurs when a transmission is suspended and the line is placed in a break state (all low, no stop bit) until released. To enter a break state, set this property to true. If the port is already in a break state, setting this property again to true does not result in an exception. It is not possible to write to the SerialPort object while BreakState is true.
