hi all, 
I am new to ecos and failed to load a example program(hello or twothreads) to Redboot in a PC target via serial line. 
gdb>set remotebaud 38400 
gdb>target remote /dev/ttyS0 
gdb>load twothreads 
Ignoring the package error,continuing... 
At the same time, the target screen became blank. 
Is it the wrong with serial line? 
However, I can use hyperterminal interact with redboot via serial line. And I can also made a example program image to PC floppy booter and succeed in debugging it via GDB. By the way, I can not see the printf output in GDB debugger. How should I configure it? 
Redboot is the lastest version downloaded from Redboot Home. 

Thanks in advance.
