We have solved the problem with the modems "locking up".  The other issue 
that was reported was affecting only folks with the E model (w/ 6.11a 
roms), in that they could not send a fax to most sites.  The problem has to
do with timing/sensitivity of the fax handshake, and we are unable to
reproduce the problem in-house.. it apparently is dependent upon the RX 
level.

If anyone has the capability to burn their own roms, I will make versions 
of the beta roms available via FTP.  please email with your modem info, 
and problems experienced.

NOTE: the fax related problems are confined to sending.. receiving is 
apparently unaffected.  Customers who were unable to send have sent their 
modems back, and they test out fine in the lab..

BTW: The release of this rom should be sometime next week.  If you can't 
burn your own roms, I would prefer that you wait until the release is out, 
and we can go through normal channels to send out the update (no charge).
