Are you wanting to use a TCP/IP stack really? Or do you want to just send a 
string through the serial port. If you want a TCP/IP stack, then you need 
to make TCP/IP networking calls to create a new connection, and be running 
PPP at both ends. If you want to just send a string out a serial port in 
eCos, read the eCos serial driver documentation, which says to use 
cyg_io_write(). If you have more questions on this, take them to the eCos 
mailing lists: <http://ecos.sourceware.org/intouch.html> as this list is 
for lwIP only.
