NAME
zsc -- serial communications interface
SYNOPSIS
zsc0 at obio?
DESCRIPTION
The zsc driver provides support for Z8530- and Z85230-compatible EIA
RS-232C (CCITT V.28) communications interfaces. The Z8530 has a 3 char-
acter buffer, and the Z85230 has a 8 character buffer. However, due to
limitations in the design of the Z85230, the driver is unable to distin-
guish it from the Z8530 and will not enable any enhanced features of the
controller.
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.

HISTORY
The zsc driver was originally derived from the sun3 zs driver and is cur-
rently under development.
BUGS

(68020 or 68030) Macintosh models and on busy systems.
