<p class="Pp">The <code class="Nm">zsc</code> driver provides support for Z8530-
and Z85230-compatible EIA RS-232C (CCITT V.28) communications interfaces.
The Z8530 has a 3 character buffer, and the Z85230 has a 8 character buffer.
However, due to limitations in the design of the Z85230, the driver is
unable to distinguish it from the Z8530 and will not enable any enhanced
features of the controller.</p>
<p class="Pp">Input and output for each line may set to one of following baud
rates; 50, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, or any other baud rate which is a
factor of 115200.</p>
