- Is this true? Not on my MultiTech's at least. As best I recall: they
- require something like <plus><plus><plus>AT<valid_AT_command><return>,
- otherwise they simply "return" to data mode and pass the data through.
- I *think* (don't have the manual handy at the moment). I'm sure someone
- will correct me if I'm wrong :-). This sequence seems "relatively" safe.
- In any event, I have to agree with you, Geoff, I've never used the
- escape sequence and I've, always disabled it in un-attended applications
- especially.
