Yup.  I hope that you're using Class 1 with this USR.  And... if you are
there is yet another problem.  All USR modems (including the Couriers that
I've tried) have a 110 - 150 ms pause after +FTH=3 and before the CONNECT
response.  For some reason this is the catalyst in some environments to
induce "no response to EOP".  And, having actually listened to the fax
squelching in these situations, you'll find that the remote isn't even
sending the MCF message, probably because it's not even hearing EOP at all.
 This is not isolated to USR modems.  All Lucent-chipet modems also suffer
from a similar delay, but theirs is 860 - 890 ms.  To USR's benefit, on the
2nd and 3rd repeats of EOP the delay is back to normal 40 - 50 ms (Lucents
are consistently delayed), and many remote systems will respond to them at
that point.  However, some do not.

The workaround for this problem is to use Class 2 with the Lucents (if
available), but I'd not recommend that you use Class 2.0 with the USRs
unless exceptionally needed.  There is a way to configure your config file
(by merging the Class 1 and Class 2.0 prototype configs except for the
"ModemType" entries) so that you can use DestControls to specify ModemType,
but I'll leave that for you to figure out if you choose to be that brave ;-)

Lee.
