[ECOS] Serial ports on SA-1100

I have an custom-port SA-1100 based system which appears to be (otherwise)
functioning properly. I'm trying to do some serial I/O in my main()
function. I've tried reading and writing data to either /dev/ttydiag
(pointed to port 0) or to /dev/ser1, but in both cases the cyg_io_lookup
works fine, and cyg_io_write and cyg_io_read return -EDEVNOSUPP (-202).
I'm not explicitly starting the scheduler in cyg_user_start() - my
understanding was that if I have not overriden cyg_start(), that is done for
me. (The code is definitely making it into main(), so I think that part is
okay anyway.)
Any idea what I could be doing wrong?
