baud, hardware flow control (RTS/CTS) and interrupt driven receives. Note
that because of the peculiarities of the 6551 chip transmits are not
interrupt driven, and the transceiver blocks if the receiver asserts flow
control because of a full buffer.</P>
<P>You need an adapter to use the builtin port, since the output levels
available at the user port don't follow the RS232 standard.</P>
