You can&amp;#39;t, other than by doing own work. However, did you read the
link I posted? You might actually want to read your own
transmissions, just to know when to turn off the RS485 driver
chip.&lt;/p&gt;

&lt;p&gt;
The alternative is to busy-loop, looking at the TEMT status
bit.&lt;/p&gt;

hi&lt;/p&gt;

&lt;p&gt;
how can i disable the receiver when i am transmitting data so that
i dont get any receive interrupt ....so before transmitting i can
disable the receive enable and after transmitting the last byte i can
re-enable the receiver ..&lt;/p&gt;

&lt;p&gt;
Regards&lt;br /&gt;
Suresh&lt;/p&gt;

Maybe this link may be of help when you are going to actually use
RS485:&lt;br /&gt;
&lt;a href="http://www.netrino.com/Articles/RS485Enable/index.php"&gt;www.netrino.com/.../index.php&lt;/a&gt;&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: LPC2378-RS485</title><link>https://community.arm.com/thread/48777?ContentTypeID=1</link><pubDate>Wed, 17 Oct 2007 00:38:20 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ee1b9824-c978-4f25-8f49-5f6a9ac758e2</guid><dc:creator>Per Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
You could use any of the built-in USARTS for RS485.&lt;/p&gt;

&lt;p&gt;
The only significant differences between RS232 and RS485 is the
driver chip used, and that you must be able to turn on/off the driver
chip depending on if you are sending or receiving. This can be done
with handshake signals, but you may as well use any GPIO pin.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
