D'Bridge, BGFAX, and USR 21k6 FAX Modem
---------------------------------------

Here are quite a LOT of words on how I've got my system running with
BGFAX, D'Bridge v1.54 and a USR DS FAX 21K6 V32-Turbo. I run this on
the BBS node 1, on an IBM PS/2 model 80, with the USR modem on COM2,
the BGFAX level I'm using is v1.10.  I've also tested with a new
D'Bridge beta 2108, which may turn out to be the next D'Bridge release.

The following describes how my set up is working and some ideas of what
you should do. The D'Bridge modem configuration file (MCF) file needs to be
changed, and you need to enter some commands on the External Receivers line
within the SECURITY/MISCELLANEOUS menu in the D'Bridge configuration
screens.

In the EXTERNAL RECIEVERS I have.....

+FCO|E:\BGFAX\BGFAX /FCO E:\BGFAX 2 Q /NF

The +FCO before the pipe is what my USR Modem reports when it answers a
FAX call, after the pipe (|) is the command line for the BGFAX reciever.
The 2 is for COM2 the Q is to tell BGFAX to receive the FAX in
Quick Link II format and the /NF is the FAX notify program that is
now included with BGFAX (see the BGFAX docs for details).
This is the fastest way to load BGFAX if you have enough extra RAM.

Another option is after the PIPE symbol, you could specify a batch file
to call BGFAX, e.g. +FCO|FAX.BAT

If there is not enough over head ram, you could try swapping D'Bridge
out by placing a "+" sign in front of the command line, +FCO|+FAX.BAT
Note the Plus (+) is AFTER the pipe!! The plus (+) on the +FCO word is
purely part of the modem response to a FAX connect. You could also drop
D'Bridge and exit with an errorlevel, +FCO|*X200 (200 errorlevel)


Now to the MCF file!!!

Some of the commands in this may be a bit over the top, but I spent a
couple of days playing with various options. Because of the limit
on the number of characters you can send to the modem in any one string
I think this combination is the safest and seems to work every time.

DIAL 2400 AT+FCLASS=0D
DIAL 4800 AT+FCLASS=0D
DIAL 9600 AT+FCLASS=0D
DIAL 19200 AT+FCLASS=0D

..... the rest is the standard relevant USR standard MCF file

Here are some notes on the above configuration to explain some of the
logic I used! The semicolons (;) may be excluded from the initialisation
strings, I read somewhere they should be included to separate FAX
commands when modem are in FAX mode, so I've included them.

You don't need the PREINIT but I've put it in for completeness.
The first INIT ATZ, just ensures that whatever your normal modem
config was, it is first restored before we set FAX mode with the MCF.
This is just in case you play with other FAX software that alters the
modem config other than the FAX changes we do in this MCF file!

The second INIT ATH0&I0+FCLASS=2.0, ensures that you put the modem
back ON hook and you initialise FAX Class 2.0. The &I0 is for
completeness, because if any FAX software puts the USR modem into
FAX Class 1 mode, &I2 is left initialised. If you have &I0 in your
saved ATZ config then you can exclude the &I0 from this line.

The INIT AT+FLI="Your Number" just sets your FAX ID number.
Note, the +FLI= command is the Class 2.0 version of Class 2 +FLID.

In the next INIT, the AT+FNR=1,1,1 sets the modem to report the
inbound FAX itentity, the +FAA=1 sets the modem to answer in call
selection mode so it will automatically differentiate between FAX
and data calls. The +FCR=1 set the modem to receive mode, I've heard
comments about some modems forgetting this command if another modem
FAX command is issued so I put this at the end of that command string.

The OFFHOOK AT+FCLASS=0M0H1 sets the Modem back to normal DATA mode
when D'Bridge is in off-line mode, it obviously takes the modem off
hook and sets the speaker OFF.

The ANSWER AT+FAA=1;A tells the modem to answer in automatic selection
mode! For some reason even though this is in a previous INIT string
I had to put this in the ANSWER line for it to answer correctly.

Note that the DIAL commands have +FCLASS=0 in them to set the modem
to dial out in normal data mode. The INIT strings set it back to
FAX mode when D'Bridge is waiting in receive mode after any dialing
out activity is completed.

If you have SPECIFIC DIAL numbers set in the COMMUNICATION PARAMETERS
menu then you will need to set those with a +FCLASS=0 as well.

The port is locked at 115200, and I use X00.SYS with the following
command in CONFIG.SYS to do that.

DEVICE=C:\X00\X00.SYS E 2 B,0,115200 B,1,115200 F=15 R=2048 T=1024

Hope that helps, if it's not all absolutely technically correct then
I apologise, but I spent two days playing with configurations and
options and it works great on my system so I thought I'd pass it on!
