Even if I uncomment the 'SerSetParams(...)' line shown above, it makes
no difference. :-(
I'm busy reading through the article mentioned below to try and see
what I'm doing wrong. So far I found no hints as to the cause of the
problem. The article does mention a CR (#13) must be sent as the last
character in each command. I appended #13 to my dial string, but still
nothing.
