1. Introduction
The TIP815
--
SW
--
12 OS
--
9 device driver allows the operation of the TIP815 ARCNET IP with a
device
--
independent interface with
t815_open
,
t815_read
,
t815_write
and
t815_cntrl
functions.
After installation of the device driver in the I/O system messages can be transmitted to and received
from the ARCNET Interface by calling the
t815_write()
or
t815_read()
functions.
Special I/O operation that do not fit to the standard I/O calls will be performed by calling the
t815_cntrl() function with a specific function code and an optional function
--
dependent argument.
This driver invoke a mutual exclusion and queuing mechanism to prevent simultaneous requests by
multiple users from interfering with each other.
