I cut out most of the boring stuff.  Anyway, your problems are many fold 
I believe.  First, the modem at the other end, is most likely using your
same ESCAPE code "+++".  So it also enters command mode when it gets
this message.  So even if you do get most of the other rather involved
instructions to work, he is now ignoring you.  Second, I have had to put
a \d between my escape characters for the necessary time out.  My
version of your dialup script would be:

usrpwc24	=W-, "" \r\rATZ "" ATV1Q0E1S2=27 OK\r AT OK\r
ATX6M0DTW6816634 CONNECT\s2400 \r "" \d\d\033\d\033\d\033 OK\r
ATQ1V0E0S2=43O "" \010\010\010\r tion:--tion: \D\r\c
Connected-\r\d\D\r\c-Connected--in:--in:

Okay, so I cut out some of the embellishments, but you get the picture.
I first set my escape code to something else, and then I dial the name
and use my new escape code to get back to command mode.  Then I reset it
to the original.  I hope this helps.  (By the way, this is how I do it
too.  If my modem is not gagged, it picks up then phone and immediately
hangs up again.)
