However this would be a regressive step in that current testing
assumptions would stop working. Granted with the automated testing things
can be munged, but right now one of the good things about eCos testing is
that for manual testing users can run through the tests and check for
failures. Right now, at least they'll get a test failure if a serial
device is not configured correctly with ser_filter magic on the other end.
Perhaps we need a something that has "requires { CYGPRI_SER_TEST_SER_DEV
!= 0 }", but that would mean having new clean configurations that don't
work by default (or if an #ifndef in the test file itself, that doesn't
compile by default). That's something we didn't want to do as a policy
decision. The alternative would be the user not knowing that serial is not
being testing, unless they look in the serial driver configuration each
time they create a new configuration. If this principle was applied to all
devices (not that they're tested much at present :-|), that would be a lot
for a user to configure before they could even manage to do a proper test run.

I don't see an interface helps any. I imagine whatever solution is used
for CYGPRI_SER_TEST_SER_DEV should also be used for CYGPRI_SER_TEST_TTY_DEV.
