http://sources.redhat.com/ecos/license-overview.html has the best summary. 
  You are only obliged to release the eCos (and RedBoot) source code - you 
can either do it directly to the people you are giving the binaries to *as 
long as you put it alongside the binaries*, or you can make it available 
to all. Read the overview :-).

BTW, there is already break support in the serial driver, it's just the 
API isn't well documented :-|. See 
devs/serial/generic/16x5x/current/src/ser_16x5x.c and search for 
CYGNUM_SERIAL_STATUS_BREAK. How did you do it?
