NAME
zsc —
serial communications
interface
SYNOPSIS
zsc0 at obio?
DESCRIPTION
Thezsc 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.
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 currently under
development.
BUGS
Data loss is possible when using high speeds, particularly on older (68020 or 68030) Macintosh models and on busy systems.
