Ehhh... Bullshit. In this case it is also sent as concatenated messages.

Think other way (and forget the above as well). You probably also have
some Big Brother or other reality show where you vote with SMS for
something. There are really *lots* of SMS sent in the prime time. SMSC is
some black box that only forward messages. There's some logic behind it to
check the correctness (database or something). It has the limited
throughtput. And it can take a couple tens of the seconds before you got
the reply from the SMSC. I think I'm going to know on Monday what's the
possible timeout.

Markus showed me the solution from mygnokii on this. And I'm not really
impressed. It is the timeout implemented in the other way. And it may loop
If the phone can handle the next request (I don't think it can) before
replying with the SMSC answer we don't have to wait actively for the
response. Anyway, at the moment I don't think that solution implemented in
gnokii is a bad way to do it.
