The SerialService is a thead service object that is meant to service attached serial ports.
Multiple pool objects may be created and multiple serial ports may be attached to the same thread of of execution. This allows one to balance threads and the serial ports they service.
The TTYPort and TTYService classes are used to form thread-pool serviced serial I/O protocol sets. These can be used when one has a large number of serial devices to manage, and a single (or limited number of) thread(s) can then be used to service the tty port objects present. Each tty port supports a timer control and several virtual methods that the service thread can call when events occur. This model provides for "callback" event management, whereby the service thread performs a "callback" into the port object when events occur. Specific events supported include the expiration of a TTYPort timer, pending input data waiting to be read, and "sighup" connection breaks.
