A select()able serial device, acting as a transport.

Method Details

### connectionLost(self, reason) The connection was lost. This is called when the connection on a selectable object has been lost. It will be called whether the connection was closed explicitly, an exception occurred in an event handler, or the other end of the connection closed it first. Clean up state here, but make sure to call back up to FileDescriptor. Overrides: `twisted.internet.abstract.FileDescriptor.connectionLost` (inherited documentation)

### doRead(self) Some data's readable from serial device.

### fileno(self) File Descriptor number for select(). This method must be overridden or assigned in subclasses to indicate a valid file descriptor for the operating system. Overrides: `twisted.internet.abstract.FileDescriptor.fileno` (inherited documentation)

### writeSomeData(self, data) Write some data to the serial device. Overrides: `twisted.internet.abstract.FileDescriptor.writeSomeData`

Class Variable Details

    ### connected Type: `int` Value:
        1
