+ Driver for the Telestrat integrated serial controller and the Atmos with a
+ serial add-on.
+ Note that because of the peculiarities of the 6551 chip together with the
+ use of the NMI, transmits are not interrupt driven, and the transceiver
+ blocks if the receiver asserts flow control because of a full buffer.
