Hi I am using SIM900A and trying to connect it with LPC1769 and make it send message by uart. The system runs with no bugs and no stops but it is not working on the SIM900A which I have tested with tera term, it turns out to be working fine. The attached is my code.

The code is not working so I set a few printf to see where goes wrong. And the result is
reply: anbcdfsdf

So apparently it skips the first printf in the send function which I would like to know why. and the "\n"after the "reply" seems not working.
Could anybody assist me on this to improve the code and make it work?

Thank you very much.
