[En-Nut-Discussion] uart help please

Hi,

I've been trying to modify the httpd example so that it can read serial data
from the same uart that it already prints out to.  Does someone know how I
can do this?  I looked at the uart.c example and tried many things to
incorporate the code from that example into the httpd, but nothing worked.

I see that the httpd example already assigns stdout to the uart, but how do
I assign stdin to the uart as well without interferring with the existing
fuctionality.  Can someone show me what changes do I need to make the
httpd.c file.  I've shown it below for convenience.  Thank you in advance.

Tony
