We bought a tty interface board for Multibus. We are trying to
install it to our SUN-2/120 (Unix version: Release 2.0), but
there is a problem with the device driver software. 

SUN Microsystems provides a manual titled "Writing Device Drivers
for the Sun Workstation." But it does not cover device drivers for
ttys. The source program of Sun's tty (zs) device driver is not
opened to the public. We are now disassembling the object
code of the zs tty driver to know how the driver should work.

Please give us any helpful information about writing TTY device
driver for the SUN work station.
