     The  proper setup for all Zoom V-series modems... Use AT&F&C1&D2  (&D0
for  Mac) for the init string.(for the White V42bis [2400] or Turbo  modems
add  S36=7 to the string) OR pick the Hayes 2400 from  software  selection.
Set  RTS/CTS  =ON, Lock DTE to 19,200 (9600+ models) or 9600  (2400  v42bis
models),  do not follow modem connect, or set Autobaud  detect=OFF/NO.   If
your software has the option to 'drop DTR to hang-up' set that to YES. When
you enter any AT command, that sets the port/modem speed, bits & parity. If
you do AT&W all current settings are saved, including speed, bits, parity &
the modem will 'awaken' with those settings.

     Any program that uses ATZ in the intitialization 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 disapprove  of
that  practice. 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.)

    Some commands for some Hayes hi-speed modems are proprietary (not CCITT
v32bis)  so picking a Hayes hi-speed modem is not the right choice. IF  you
must pick a modem, pick a Hayes Smartmodem 2400.

     >>>   I always recommend you start any string AT&F in all programs  to
make sure it's set back to factory, eliminating any conflicting setup  from
another program.

     >>>See Appendix F for pin assignments on external. When using a  9-pin
cable only pins 2-8 and 20 are used (of the 25 pins).

     Some  Fax  software (Winfax for example) does not reset the  modem  to
Data mode when done. AT+FCLASS=0 will reset to data mode.
