</blockquote><h1><i>sysMailboxEnable</i>(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong><i>sysMailboxEnable</i>(&nbsp;)</strong> - enable the mailbox interrupt</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS sysMailboxEnable
    (
    INT8 * mailboxAdrs /* mailbox address */
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine enables the mailbox interrupt.
<p>
</blockquote><h4>NOTE</h4><blockquote><p>
This routine has no effect, since the hardware does not support mailbox
interrupts.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
ERROR, always.

</blockquote><h1><i>sysBusTas</i>(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong><i>sysBusTas</i>(&nbsp;)</strong> - test and set a location across the bus</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>BOOL sysBusTas
    (
    INT8 * addr /* address to be tested and set */
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine performs a test-and-set (TAS) instruction across the backplane.
<p>
</blockquote><h4>NOTE</h4><blockquote><p>
This routine is equivalent to <b><i><a href="../hpux/sysLib.html#vxTas" >vxTas</a></i>(&nbsp;)</b>, since there is no VMEbus.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
TRUE if the value had not been set but is now,
or FALSE if the value was set already.

    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine creates a device on one of the pcConsole ports.  Each port
to be used should have only one device associated with it, by calling
this routine.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
OK, or ERROR if there is no driver or one already exists for the
specified port.

<p>
Serial device interrupts cannot be connected in <b><i><a href="./sysLib.html#sysSerialHwInit">sysSerialHwInit</a></i>(&nbsp;)</b> because
