Error class constants are as follows:
The following class constants can be used to test the LastErrorCode value.

|---|---|---|
| NoError | 0 | No error code. |
| AccessDenied | 100 | Access denied. |
| PortNotFound | 101 | Port not found. |
| InvalidOptions | 102 | Invalid options. |
| BreakCondition | 103 | Hardware detected a break condition. Usually due to a signal rate mismatch. |
| FramingError | 104 | Hardware detected a framing error. Occurs when the designated "start" and "stop" bits are not valid. |
LastErrorCode can be set as well as read. This is useful for subclassing a Serial.
