[ECOS] network test problem on ipaq

[Weilong Li <weilongli2000 at yahoo dot com>]

I try to run tcp_echo, tcp_source and tcp_sink
program on ipaq.

>From linux host, I used serial port to connect
ipaq, then I used gdb to remotely run tcp_echo, after
tcp_echo is running, and I run tcp_source and 
tcp_sink, but I got "no route to host" message.
And I cannot ping ipaq.

While before I run tcp_echo, I can ping ipaq, and
tcp_source and tcp_sink can successfully run and
waiting for packets. But I cannot run tcp_echo
through gdb, it simply cannot load the program.

So it seems there are conflicts even I used
serial port to run tcp_echo, and used
ethernet interface to run tcp_sink and
tcp_source. Please help.

thanks,

Weilong
