Hi, any modem gurus out there?

Sorry for the windy post, but I've included as much info as possible!

Background:
--------------------------------------------------------------------------------
-------------------------
   I've been trying to setup a simple home>office or
client>support file transfer sytem. I needed a sytem that would
automate file transfers - on demand.
  The requirements were:
       a. Run in MS-DOS mode.
       b. Small memory footprint, so I could shell-out to it.
       c. Transparent to the user. i.e. NO runtime intervention
           required.
       d. Would work for 99%(all?) of modems.
       e. Initial setup be a 'no-brainer', - which comm port?

  So far I've had varying degrees of success. I've tried a few
shareware packages from the net, but most failed to meet one or more
of the above requirements.
--------------------------------------------------------------------------------
-------------------------
For my own education:
   Are AUS modems setup with different defaults than US modems?
      A common thread with most US progs is that they set S0=0.
   Do all modern modems have the hardware to send a 'ring received'
message to the software - even when S0=0 ?
   If so, what's required by the software program to detect the
'ring'?
--------------------------------------------------------------------------------
-------------------------

I thought I had it licked when I used batch files to call DSZ for the
file-transfer protocol and a program like MODEM.EXE to send AT
commands to the modem - send ATDT to dial and ATS0=3 to detect and
answer the ring.
While all the above worked and files transfered ok, now I CAN'T GET
THE MODEM TO DROP THE CALL.
I've tried the usual ATH0 and an internal MODEM.EXE command called
'DROPDTR'. Also tried ATZ, AT&F, pausing between commands, etc.
The modem lights flash but the modem seems to ignore all AT's after
DSZ has returned. The only way to drop the call is to switch off the
modem or reboot if it's an internal job.

Any ideas?????
Frustrated.
