1-13-94              The use of ATZ / AT&W

     Any program that uses ATZ in the initialization or command string, is
expecting  that  it  is the ONLY software that you will  be  using  on  the
computer  with that modem. As that is extremely unlikely, we dissaprove  of
that practice strongly. Replace the ATZ with (99% of the time)  AT&F&C1&D2.
Put in whatever they use for a carraige return (if they show one). If there
are  additional  parameters  put  them between the  above  string  and  the
carraige  return  character(s).  (Most often the ^M is  used  for  carraige
return.)

     If  you  must  use ATZ, then I suggest you store  it  in  profile  '1'
(profile  '0' is default) so any program that requires default  will   work
correctly.  Store  with AT...&W1 and then instead of ATZ use ATZ1  and  you
will use your stored profile '1', leaving profile '0' alone as default.  If
the  particular  software cannot be set to ATZ1, then you  can  temporarily
make profile -1 the default by using AT&Y1 in a terminal program (you don't
have  to save &Y1).  Use AT&F&W to restore profile 0 to default. Then  you
can  then restore the modem to factory default quickly with ATZ which  will
call profile 0. AT&Y0 will return profile -0 to default (you could put  &Y0
in the init string of the terminal/fax init you commonly use.)

     ATZ  or  ATZ1 must be the ONLY commands in a string. Calling  Z  in  a
string overwrites any command ahead of it, and any command after Z does not
get issued.
