[ECOS] How to check the input of STDIN channel?

[wang cui]

Thanks for your reply.

If I use the full interrupt driven serial driver for console, I think the 
driver will be intialised until the "cyg_io_init()", then the ealier output 
will be missing?

And I also want to printf messages in ISRs, can the "full interrupt driven 
serial driver" be used?
