DO NOT USE THIS HELP FILE FOR IM 2.28 OR LOWER.  IM 2.29c ADDED AN EXTENDED
ANSWER FIELD, AND IT IS ASSUMED YOU ARE USING THAT VERSION OF INTERMAIL!

NOTE: USR Sportster 14.4K modems cannot be used with BGFAX and FD

NOTE: I do not recommend using the 21600 USR modem (v.32terbo) with BGFAX
      because of many problems in the fax mode (09/20/93 and 12/08/93).

The only USR modem I recommend using with BGFAX is the 28800 V.Everything
with at least the 12/02/94 FLASH firmware.  The 28800 Sporster modem should
work with the same configuration, but I have not tested with one.

Please make sure the following two items are true before proceeding...
(1) Your modem is NOT set to "Auto Answer" mode (REGISTER S0 MUST EQUAL 0)
(2) You have already put all relevant DATA commands for the BBS into NVRAM

Note that, generally, fax (AT+F) commands CANNOT be stored in NVRAM.
Here is the relevant information from IMSETUP ...

[IMSETUP] Modem -> Advanced Setup -> Command Strings
  On-hook ... ATZ|
  Dial ...... AT
   Prefix ... +FCLASS=0DT
  Init-1 .... ATZ|
  Init-2 .... ATS0=0+FCLASS=2.0|
  Init-3 .... AT+FLI="713 555 1212"|

  +fclass=0dt              enables data mode operation on outgoing calls
  +fclass=2.0              enables fax mode operation
  +fli="713 555 1212"      sets your FAX ID, up to 20 characters
  +fnr=1,1,1               tells modem to let BGFAX know connect speed

[IMSETUP] Modem -> Advanced Setup -> Answer Control
  Manual answer    Yes
  Force answer ... AT+FCLASS=2.0|~AT+FAA=1;+FNR=1,1,1;A|
  Answer delay ... 2

The "+faa=1" causes the modem to answer adaptively, i.e., to automatically
determine whether the incoming call is fax or data and return the response
to the modem.  Why are we duplicating the "+fclass=2.0" command?  In case
you were attempting to dial out and experience a "NO DIALTONE" situation,
it will cause the modem to reinitialize fax mode so that the +faa=1 command
will be accepted.  The answer delay may need to be modified if you are
using an external Caller ID box.

[IMSETUP] Modem -> Advanced Setup -> Connect Strings

You will see a list of 14 or so preconfigured connect strings, press
<INSERT> to add one.  The USR modem will report "+FCO" on when an incoming
fax call is detected when in Class 2.0 adaptive answering mode.

  Connect Message                          Speed  EC  BBSexit  Terminate

  +FCO                                     19200  N   0        255

-------------------------------------------------------------------------

Notice that "BBSexit" is equal to ZERO.  "Terminate" instructs IM to exit
IMMEDIATELY as it receives the fax response.  ("BBSexit" tells the user
to press <Esc>, and obviously, a fax machine cannot do that.)  The "19200"
speed is basically a dummy variable, as it could be any speed number.

IMRUN.BAT should contain something similar to ...

@echo off
c:
cd\im
im
if errorlevel 255 goto fax
if errorlevel 103 maint.bat
if errorlevel 102 toss.bat
if errorlevel 101 local.bat
if errorlevel 100 dobbs.bat
goto end
:fax
  rem ---1 is for com1, and z is for zfax format
  bgfax /fco:4 c:\bgfax 1 z
  rem ---if /fco:4 gives you problems, try using /fcos instead
  imrun.bat
:end

P.S... USR's FAX/ARQ light WILL flash when waiting for calls!
