All FD*.TXT files are good for both FD 2.12/SW and FD 2.20/ML.  One note
is needed for FD 2.20/ML: [FDSETUP] Modem -> Fax -> Internal = "NO".

NOTE: US Robotics owners, please read over the USR section in the READ.ME
      file before proceeding!

Please make sure the following three items are true before proceeding...
(1) Your modem is NOT set to "Auto Answer" mode (REGISTER S0 MUST EQUAL 0)
(2) DIP switch #5 is in the "SUPPRESS AUTO ANSWER" position
(3) 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 FDSETUP ...

[FDSETUP] Modem -> Default Settings -> Command Strings
  On-hook ... ATZ|
  Dial ...... AT
   Prefix ... +FCLASS=0DT
  Init-1 .... ATZ|
  Init-2 .... AT+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

[FDSETUP] Modem -> Default Settings -> 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.

[FDSETUP] Mailer -> Errorlevels
  Fax ... 255

[FDSETUP] Modem -> Default Settings -> Messages
   Fax ... +FCO              <-- RIGHT
   Fax ... CONNECT +FCO      <-- WRONG

FDRUN.BAT should contain something similar to ...

@echo off
c:
cd\fd
fd
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
  fdrun.bat
:end

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