Hi! 
I work with LPC2138 ARM and i want to establish the communication
between the microcontroller and the Modbus.As slave the
microcontroller receives a frame from the master(modbus).The problem
is that i don&amp;#39;t know how the slave can respond to the</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: communication with Modbus in C</title><link>https://community.arm.com/thread/99432?ContentTypeID=1</link><pubDate>Tue, 17 Jul 2007 04:22:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:14ca89bd-a371-4f69-8852-2b1d31dfe317</guid><dc:creator>Peclare Mambe</dc:creator><description>&lt;p&gt;&lt;p&gt;

I am using RTU form of Modbus.&lt;/p&gt;

You haven&amp;#39;t mentioned if you are using the ASCII or RTU form of
Modbus.&lt;/p&gt;

&lt;p&gt;
You can emit binary strings using embedded hex codes, like
&amp;quot;\x10\x12\x14&amp;quot;, but normally printf() isn&amp;#39;t really the best way if
you are using a binary protocol. Then it is normally better to get
and put the individual characters.&lt;/p&gt;
