Which would be /dev/ttydiag which is a somewhat crude interface to
the diagnostic serial drivers.

I think you should try using the interrupt driven serial
interface, which will require some additional configuration.

I just tested this on a MOAB board; here's how I configured
the system:

  % ecosconfig new moab net
  % ecosconfig import moab_serial_config.ecm
  % ecosconfig tree

Try this and see if it helps.
