modem problem

[Admin]

Ok -- here's the scoop.  I'm calling the site "elric" (with Uutry) and i'm doing
it over a bidirectional serial port, /dev/cul0, using uugetty:

Everything works fine (in a relative fashion) if i gag the modem by turning off
verbose mode.  But this causes unnecessary delays while i time out waiting for
the login: prompt instead of looking for "CONNECT".  It *does* work however.

But, what i wanted to do is (silly me) speed this process up somewhat.  The
problem is to have the modem in verbose mode whilst calling OUT, but in "gag"
mode while otherwise idle.  So, i concieved of the somewhat-short-of-
brilliant idea of initializing the modem to be in verbose mode; then waiting
until i get CONNECT and going temporarily into the modem's command mode with
"+++", issuing the gag order and finally returning on-line with ATO and
preceding apace from there on as if nothing had happened.  At most, just a few
seconds delay would have occurred between the CONNECT and my initial CR to
the called site's getty.  Certainly no worse than the current situation.

But nooo..  As soon as i issue the +++, the carrier drops the carrier like a hot
potato.  What the heck am i doing wrong here?  The USR manual mentions nothing
like:
	"As soon as the +++ is entered the modem not only
	 enters the  command state,  but also  immediatly
	 drops the carrier like a hot potato"

(my severe embellishment, a hacker's inalieanable rite (sic))

Has anyone else run into this or is this just yet another fundamental mis-
understanding of the way the modem/uugetty is supposed to work (not a terribly
unusual situation, i might add (:-)) 

The hopefully relevant data follows, in my quite imitable, verbose fashion:
