ZSC(4)              NetBSD/mac68k Kernel Interfaces Manual              ZSC(4)


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

     Data loss is possible when using high speeds, particularly on older
     (68020 or 68030) Macintosh models and on busy systems.
