Voice B.J. Guillot Data/Fax 713.893.9320 2611 Rushwood Circle 713.893.9124 Houston Texas 77067-1941 Copyright (C) 1993 B.J. Guillot. All Rights Reserved. ============================================================= BGFAX 1.0 Beta 5 WED 25 AUG 93 ============================================================= Dedicated to Gene Roddenberry 1921-1991 ------------------------------------------------------------- ABSTRACT FidoNet 1:106/400.0 ------------------------------------------------------------- BGFAX allows SYSOPs to accept faxes on their BBS line. BGFAX can also send faxes. (While BGFAX was originally designed just for sysops, it can also be used by Mr. Joe User who, like me, hates TSR based fax programs that all the commerical fax software developers love for some reason.) BGFAX is a tool designed for use with *ANY* Class 2 compliant fax modem. The fax modem must also support fully functional ADAPTIVE ANSWERING. Common Class 2 fax modems include the Supra, Practical Peripherials (may require purchase of a newer ROM revision if you are using an older model), Zoom, ZyXEL, etc. BGFAX will *NOT* function with Class 1 *ONLY* fax modems. Common Class 1 *ONLY* fax modems include *ALL* USR fax modems, Digicom Scouts, the AT&T Dataport, and the SupraLC. BGFAX can be used in FOUR distinct modes. FRONTEND MODE ... BGFAX will answer the telephone line ITSELF, handle events, pass data calls to a front end compatible BBS, and take fax calls. REAR END MODE ... BGFAX will be called from another program when an incoming fax is detected. FidoNet sysops using front end mailers such as Front Door, Intermail, D'Bridge, Dutchie, etc. are required to use this mode. The mailer must support the ability to exit to BGFAX when a fax is coming. SEND MODE ....... BGFAX has the ability to send faxes to another fax machine. (At this time, the file to be sent must already be in converted fax format.) INITIALIZATION .. BGFAX will only initialize the modem, and then quit. This mode is provided for people who need to use BGFAX in rear end mode, but their Fido mailer (or BBS software) will not allow the long initialization strings required for fax usage. ------------------------------------------------------------- INCLUDED FILES ------------------------------------------------------------- 1.

BGFAX can also be obtained from Fido 2:512/39. This system is called The Owl's Nest and is the Dutch Supra Distributor. They have three nodes: +31 0.2155.10921 +31 0.2155.12571 +31 0.2155.28096 ------------------------------------------------------------- MISCELLANEOUS NOTES ------------------------------------------------------------- BGFAX takes the fax call itself. It does *NOT* require any special TSR drivers to be used and does *NOT* pass control to another fax program to receive the fax. ...HOWEVER... You *WILL* need some type of external fax program to VIEW and PRINT the received fax. BGFAX currently supports two popular fax formats. Smith Micro Software's Quick Link II, which is included with several faxmodems, and ZyXEL's ZFAX software. (ZFAX will not function on a normal Class 2 faxmodem, but it will allow you to view and print BGFAX faxes stored in ZFAX format.) If anyone can get me the formats for other popular packages, I will gladly add them to BGFAX if its not too much trouble. A number of people have requested WinFax format, but I can't find any information on Delrina's WinFax file format. PLEASE NOTE: BGFAX does not need nor use a FOSSIL driver. BGFAX has internal communication support for all UART types including the 16550A FIFO chip. BGFAX assumes ... COM1=3F8x4 COM2=2F8x3 COM3=3E8x4 COM4=2E8x3 If you are using a nonstandard port configuration, whenever BGFAX requires a port number to be entered (such as po=2), instead of entering the port number, enter the base address and IRQ seperated by an 'x' character (such as po=2E8x5). BGFAX requires the base address be given in hexidecimal notation. If you are using a ZyXEL modem, whenever you specify the com port for BGFAX, you will need to put an exclamation point, !, i.e., po=2! so that BGFAX will not attempt to relock the DTE. Most modems work fine without the !, but remember this option is available. I've also heard that the Zoom VFP Internal Fax Modem may also require this ! option. BGFAX supports Desqview's alternate video buffer zone, if used, and will return ticks to other tasks. This program was compiled under Borland's Turbo Pascal 7.0. I do all testing with a Supra Fax Modem (ROCKWELL based) v.32bis external with V1.80-02 firmware and Frontdoor 2.02/NC running on a 386DX/40. I also routinely test BGFAX with a generic no-namer 2400 data, 9600 send/receive fax (SIERRA based) modem from Computer City running on the ever-so-slow 286/8. ------------------------------------------------------------- QUICK TUTORIAL ON SOME FAX CLASS 2 COMMANDS ------------------------------------------------------------- AT+FCLASS=? =========== This command will allow you to see if your fax modem supports the "unofficial" Fax Class 2 standard. The modem should report back a string similar to: 0,1,2 This indicates the modes the modem is capable of opering in. 0 means data, 1 means "official" Class 1, and 2 means "unofficial" Class 2. (3 may indicate "official" Class 2.0, which is not necessiarly compatible with BGFAX.) If the modem response if "ERROR" this means your modem does not have any CCITT standard fax capabilities. The above command is explained only for people's curiosity. BGFAX should always be used in data mode. If you issue an "AT+FCLASS=2" command, you may disable adaptive answer and cause your modem to attempt a fax connect on *ALL* incoming calls. AGAIN, do *NOT* use the "AT+FCLASS=2" command. GROUP III and CLASS 2 ===================== Many people are often confused between the terminology "GROUP" and "CLASS" regarding fax modems. ALL FAX EQUIPMENT is "GROUP 3" compatible. This includes fax machines, fax modems, standalone PC fax cards, etc. Group 3 just defines the fax specifications, e.g., black-and-white, the resolutions, etc. When Group 4 fax machines are available to consumers, they will offer color fax capabilities, but are fax modems will still only do black-and-white. "CLASS" refers only to fax modems. CLASS has NOTHING AT ALL to do with fax machines. Class 1, Class 2 and Class 2.0 are different methods of sending commands to a fax modem from a computer serial port. Many fax modems offer the Class 2 command set. AT+FAA=1 ======== This command will put your modem in ADAPTIVE ANSWERING mode. This means your modem will properly mate with either a standard modem data call or a fax machine/fax modem. Some modems, such as the Supra, will report a "FAX" response the instant a fax CNG tone is heard from the remote end. Some modems are brain dead and will report "FAX" whenever an "ATA" command is issued to the modem regardless of whether the incoming fax is data or fax. All modems, on true fax calls, will report a "+FCON" response code when the fax connection is truly established. (This is similar to a "CONNECT 14400" on a data call.) Many modems are slightly brain dead and will forget the +FAA setting when another command is issued to the modem. To ensure you always answer in adaptive mode, rather than using "ATA" to answer the phone, use the following: "AT+FAA=1;A". The ";", semicolon, is used as a seperator for fax commands. Some modems, such as the Supra, do not require it. Others, such as the PPI, will "ERROR" out if the semicolons are not used. A final note about adaptive answering: IT IS NOT 100% ACCURATE. Every now and then, your modem may get confused and think a data call is a fax call. There is nothing I can do about this as it is most likely a firmware problem with the modem. Some modems are very brain dead and allow low speed data callers to call the BBS, but all high speed callers are treated like they are fax machines. (That is NOT GOOD.) The only way to cure this is get a ROM chip upgrade to the modem, if a newer version exists. You'll just have to experiment and make sure your adaptive answer works about 95% of the time, or whatever you decide is good. The Supra Fax Modem, for example, is pretty good concerning adaptive answering. (Note that very earlier versions of the Supra, did not offer adaptive answering until the 1.2-H and 1.2-J ROMs appeared on the scene.) However, many older fax machines do not send out a CNG tone when they are engaged. Many fax modems, including the Supra, won't know what to do, and will assume the old fax machine is really a data caller. Again, this is not good, but its not that much of a problem. Tell the operator of the old fax machine to push their "START" button *IMMEDIATELY* after dialing the last digit of the telephone number instead of waiting to hear the fax tones on our end like many office people do. AT+FCR=1 ======== As silly as this command may sound, it gives permission to your fax modem the ability to accept fax calls. The fax modems default to *NOT* allow incoming fax calls (EVEN IF ADAPTIVE ANSWERING IS ENABLED!) So, just make sure +FCR is always equal to 1. AT+FLID="TRANQUILITY BASE" ========================== The above command sets your modems fax ID string. This is the string that is send to the remote end on fax connects. (It's the deal that's printed on the little 'confirmation reports' that many fax machines make.) The fax ID can ONLY BE A MAXIMUM OF *20* CHARACTERS. If you try to stuff more than 20 characters in a fax ID string, the modem will respond with an "ERROR". DO NOT USE HIGH-BIT ASCII CHARACTERS IN THIS STRING. Use only simple letters, numbers, and punctuation marks. (High-bit ASCII characters include foreign accented letters, inverted question marks, etc.) I've been told that some older fax machines will go nuts if you use a fax ID with ALPHABETIC letters and that the only true valid values, as specified by the CCITT, are PLUS, SPACE, DASH, and the numbers ZERO through NINE. I've never seen this happen personally, but am informing you of it nevertheless. AT+FDCC=1,5,0,2,0,0,0,0 ======================= The above command is what the power on defaults to a 14400 fax modem are, with one exception. The first number, 1, allows your fax modem to accept high resolution fax documents. The power on default to most modems are to accept only low resolution documents. The second number, 5, allows your fax modem to use fax speeds up to 14400 bps. If you issue the above command on a fax modem with an upper limit of 9600 on fax tranmissions, you will receive an "ERROR" or cause the modem to behave odd. Use this string on a 9600 fax modem: AT+FDCC=1,3,0,2,0,0,0,0 The remaining numbers are not that important. Changing them around, though, may cause BGFAX to fail. The command can also be abbreviated to "AT+FDCC=1,5" or "AT+FDCC=1,3". STACKING ======== A single command string can be made using what we need ... AT+FAA=1;+FCR=1;+FLID="BGFAX IS GREAT";+FDCC=1,5,0,2,0,0,0,0 However, if you are using BGFAX in rear end mode with a Fido mailer, you may have a hard time of making an initialization string that long, so you may be required to split the line into a few pieces. Remeber to make your ATA command "AT+FAA=1;A" if it is possible to change in your mailer. AT+FMFR? ======== If you want to find out who makes the fax datapump for your modem, this command should tell you if you enter it in while in terminal mode. My Supra (and many others) report "ROCKWELL". My Cheap 2400 data, 9600 S/R fax modem reports "SIERRA". Other modems report "EXAR". FAX MODE ======== Probably 95% of you will be using BGFAX with a high speed modem (v.32 or v.32bis). Many of you may have started off with slower 300, 1200, or 2400 modems from long ago. If you can remember back that far, when an incoming data call came in, you would see a string like "CONNECT 1200". If your port was set at 2400, you would garbage on the screen unless you shifted your bps rate down to 1200 to match that of the caller. Many newer terminal programs refer to this speed shift as "Autobaud". Modern modems require your serial port be locked at a specific speed (such as 19200, 38400, 57600, etc.) so that you can achieve higher thruput via compression engines such as MNP and v.42bis. The modem-to-modem speed may only be 14400, but the modem-to- computer speed stays "locked" at 38400. Autobaud is not required, and if used, would result is garbage on the screen. Why am I telling you all this? Well, I don't know who's silly idea it was, but the powers that be decided that fax modems should use the ancient method of changing the port rate when a fax is incoming or outgoing. After your modem reports the result code "+FCON" all further communications *MUST* be done at 19200 bps, even if you are locked at 38400 or 57600. If the port speed is not relocked at 19200, nothing but garbage will come on the screen. I'm telling you this because I frequently get mail asking me why I'm changing the port speed to 19200. It's not my fault! That's the way is has to be done! The only modem that I know that does not require this idiotic speed shift is the ZyXEL modem. In fact, a special option must be used to tell BGFAX you are using a ZyXEL or BGFAX will fail as it will try talking to the ZyXEL modem at 19200 instead of 57600 or whatever rate it's locked at. ------------------------------------------------------------- FRONTEND MODE ------------------------------------------------------------- If you plan on using BGFAX in Frontend mode, you need to do a couple of things first. 1. An evironment variable called BGFAX needs to be inserted in your AUTOEXEC.BAT or someother batch file. Example: SET BGFAX=C:\BGFAX This environment variable points to the location of your BGFAX configuration file and the directory where faxes will be received into. 2. Make sure the BGFAX.CNF configuration file is in the directory pointed to by the BGFAX environment variable and make any changes you think necessary. The included configuration file is self explantory. I won't repeat the format here. 3. BGFAX can exit with 4 possible errorlevels: 4 - fax was received 3 - local logon 2 - data call 1 - restart batch file If no errorlevel is encountered, it means the sysop aborted BGFAX by pressing the [Esc] key or a serious error occurred. 4. When BGFAX is waiting for a call, pressing Ctrl-R will reset the on screen counters. Ctrl-A will force BGFAX to send the answer string to the modem. 5. When a data call comes in, BGFAX creates a DOBBS.BAT file that looks like so: C:\BGFAX\EXEBBS.BAT 9600 1 528 /ARQ The first parameter is the DCE data speed, then the com port, number of minutes until the next event, and then the error correcting string, if any. The EXEBBS.BAT file must be created by you so that your bulletin board software is loaded up in frontend mode (ie., the data connection is already hot.) When you speed to specify the DCE rate in your EXEBBS.BAT file use the variable %1 and the com port is %2, etc. ------------------------------------------------------------- SEND FAX MODE ------------------------------------------------------------- If you wish to have BGFAX send a fax file that it has received to another fax number or send a fax file that has already been converted by Quick Link II or ZFAX. BGFAX /SEND FAX0001.ZFX 893-9124 See the BGFAX.CNF file for more info, such as maximum amount of busy signals and failures before exit, etc. At this time, only previously converted fax files can be sent. (i.e., ASCII files have to be translated to ZFAX .FAX format or QLII .QFX format.) BGFAX will exit with an errorlevel of 1 if the fax was not successfully sent, or no errorlevel if everything worked okay. ------------------------------------------------------------- INITIALIZATION MODE ------------------------------------------------------------- If you want BGFAX just to initialize the modem, you can have it do so with the BGFAX /INIT parameter. BGFAX will get the port, speed, and initialization strings from the BGFAX.CNF file in the directory specified by the BGFAX environment variable. This mode is provided for people who need to use BGFAX in rear end mode, but their Fido mailers (or BBS software) do not allow them to use the long initialization strings required for fax usage. ------------------------------------------------------------- REAR END MODE (FIDO MAILERS, ETC.) ------------------------------------------------------------- Rear end mode is useful for those of us who are FidoNet members where a Fido mailer is required to be running 24 hours a day. It will be your job to figure out how to get your mailer to exit to BGFAX when your modem informs the mailer a fax call is coming through. (See the BGFAX.HLP file for hints on specific mailers.) First of all, though, you need to discover what string your modem sends when it has reliably mated with an incoming fax. My Supra Fax Modem for example returns "FAX". All modems eventually report "+FCON". In my opinion, it is better to trigger your mailer to exit on "FAX" *IF* your faxmodem supports it. I've heard about some brain dead modems to report "FAX" whenever an "ATA" is sent to the modem. If your modem does that, do *NOT* use "FAX" as the trigger string in your mailer. Why is it better to use "FAX" as a trigger string? My Supra reports "FAX" as soon as it hears the CNG tone from the remote fax device. It takes about 1.5 seconds or so for the fax machine and my Supra to mate, which gives BGFAX plenty and plenty of time to load up and take the fax, even on slow computers. (It should be noted that your mailer must exit *IMMEDIATELY* upon receipt of the fax trigger string, because after those 1.5 seconds, if the remote fax machine cannot mate, it will hangup!) For those whose modems do not report "FAX", you will have to use the "+FCON" string as the trigger string. One downside to this is that it makes timing much more critical and you will probably miss your chance of obtaining the remote fax ID string. Your mailer should run BGFAX as soon as the trigger string comes in the port. It should call BGFAX in the following manner: BGFAX /how [faxpath port faxtype [pid]] FAXPATH will be the directory where incoming faxes are to be placed. PORT is a valid communications port from 1 to 4, or, optionally, a hexidecial base address and IRQ formatted as followed "3F8x5". Also, optionally, if the port has a bang, !, following it, it will force the port to stay locked at the current speed rather than shifting to 19200 on fax connects. (THIS '!' IS TO BE USED ONLY FOR ZYXEL MODEMS, OR FOR PEOPLE THAT REALLY KNOW WHAT THEY ARE DOING.) FAXTYPE is a single character 'Z' or 'Q'. 'Z' for ZyXEL ZFAX format, 'Q' for Smith Micro Software's Quick Link II fax format. The /how deal is the most critical switch. There are three possible settings. /FAX ... Use this on modems like the Supra where the "FAX" response is generated by the modem, otherwise, you will have to use one of the following: /FCON ... If your modem reports +FCON only, try this option first. If it doesn't seem to work, try ... /FAST ... what is the difference between these last two? If you use the /FCON switch, BGFAX will assume the fax machine has already fully mated with your fax modem, and will BLINDLY tell the remote fax machine to start sending a page. HOWEVER, if the machines have not fully mated, this will distrub the mating process and make both ends hangup. If you use the /FAST switch, BGFAX will assume the fax machine is still in the process of mating with your modem and will wait for the "OK" signal before telling it to start sending the page. The /FAST switch may be necessary on very fast computers, or just depending upon what type of modem is being used. Consider these situations ... (My Supra exits with the "FAX" result, but for testing purposes, I ignored it to show you an example of how the /FCON and /FAST switches work. In reality, I *SHOULD* use the /FAX option as it works more reliable, but this is for example purposes only) ... a. Running FD 2.02/NC with a 386DX/40 and my external modem, I have to use the /FAST option or BGFAX will hang up right away when it is called. b. Running FD 2.02/NC with a 286/8 and my external modem, I have to use the /FCON option or BGFAX will sit there and eventually time out after 40 seconds. c. Running FD 2.02/NC with the same 286/8 and my INTERNAL 2400 data, 9600 send/receive fax modem, I must use the /FAST option or BGFAX will sit there and timeout. When a fax is inbound, I call BGFAX in rearend mode with the following command line for my Supra: BGFAX /FAX C:\BGFAX 1 Z The /FAX means that I used the modem response "FAX" as a trigger for FD (see BGFAX.HLP for more details), C:\BGFAX is the path where I want all faxes to be stored, "1" is the communications port, and the "Z" represents I want faxes saved in ZyXEL's ZFAX image format. If you want to run BGFAX on a multinode system, an optional fifth parameter can be used. This fifth parameter can be up to three characters and it is called the PID. Example: BGFAX /FAX C:\BGFAX 1 Z 99 The only difference between the command above and the previous one is that rather than making a BGFAX.LOG, all log entries will be written to a file called BGFAXpid.LOG, in this case, BGFAX99.LOG. ------------------------------------------------------------- AFTER YOU RECEIVE THE FAX ------------------------------------------------------------- NAMING CONVENTION ================= The name of the fax file will be FAXnnnn.xFX where "nnnn" is a number that is padded with zeros and "x" is the letter "Z" or "Q" depending upon which fax format you save the file in. If you ever see a BGFAX.TMP file in your directory, it should *NOT* be there, as it should have been renamed in the FAXnnnn.xFX format. If it is there, it means some kind of problem happened during the fax reception. FAXIN.LOG ========= BGFAX creates a BGFAX.LOG file that contains a bunch of information that is mainly only for debug purposes. A much cleaner log file is called FAXIN.LOG and looks like this: Date Time ET Bytes Rate Filename Remote Fax ID Pgs Notes ------------------------------------------------------------------------------- 07-22 11:52 00:42 18183 9600*FAX0001.ZFX Not Available 2 Finished 07-22 18:04 00:38 18182 9600 FAX0002.ZFX Not Available 2 Not Done 07-22 21:30 00:29 17793 14400*FAX0003.ZFX 7138939124 1 Finished 07-22 21:42 00:29 17541 14400 FAX0004.ZFX TRANQUILITY BASE 1 Finished 07-22 21:44 00:32 16941 9600*FAX0005.ZFX Null ID Received 1 Finished 07-22 22:21 01:22 107392 14400*FAX0006.ZFX 7132424708 1 Finished The asterick between the fax DCE rate and the filename indicates the fax was marked as high resolution. "Not Done" under Notes means that BGFAX believed more pages were to have followed, but were not actually received. "ET" is estimated time. Everything else is self explanatory. DOPRINT.BAT =========== After you successfully receive a fax, BGFAX will exit with an errorlevel of 4 and create a DOPRINT.BAT file. Example: C:\BGFAX\EXEPRINT.BAT C:\BGFAX\FAX0086.ZFX You do not have to do anything with this at all, but it is provided for those of you who wish to print faxes as they are received. It will call the EXEPRINT.BAT file and pass it the parameter with the path and name of the fax file that was just received. If you are using Smith Micro Software's Quick Link II, for example, and are one of those people that leave your printer on 24 hours a day, your EXEPRINT.BAT file might contain this: @echo off printfax %bgfax%\%1 24pin.qlp ------------------------------------------------------------- HANGUP STATUS CODES ------------------------------------------------------------- When BGFAX reports "Problematic fax reception", it will indicate a fax hangup code, such as [+FHNG: 73]. This chart, taken from the Supra CLASS_2.TXT fax command set documentation (which, I believe was taken from the Rockwell Class 2 documentation), allows you to match up the +FHNG message with its true meaning. For example, +FHNG: 73 would indicate "T.30 T2 timeout, expected page not received", which really does not say much, but it may give you some clue. I don't know what most of these mean myself, so I don't know whether it will provide you any luck or not, but, many people asked that it be included, so here it is. |------------------------------------------------------------| | Code | Cause Description | |----------|-------------------------------------------------| | 0-9 | CALL PLACEMENT AND TERMINATION | |----------|-------------------------------------------------| | 0 | Normal and proper end of connection | | 1 | Ring Detect without successful handshake | | 2 | Call aborted, from +FK or AN | | 3 | No Loop Current | |----------|-------------------------------------------------| | 10-19 | TRANSMIT PHASE A & MISCELLANEOUS ERRORS | |----------|-------------------------------------------------| | 10 | Unspecified Phase A error | | 11 | No Answer (T.30 T1 timeout) | |----------|-------------------------------------------------| | 20-39 | TRANSMIT PHASE B HANGUP CODES | |----------|-------------------------------------------------| | 20 | Unspecified Transmit Phase B error | | 21 | Remote cannot receive or send | | 22 | COMREC error in transmit Phase B | | 23 | COMREC invalid command received | | 24 | RSPEC error | | 25 | DCS sent three times without response | | 26 | DIS/DTC received 3 times; DCS not recognized | | 27 | Failure to train at 2400 bps or +FMINSP value | | 28 | RSPREC invalid response received | |----------|-------------------------------------------------| | 40-49 | TRANSMIT PHASE C HANGUP CODES | |----------|-------------------------------------------------| | 40 | Unspecified Transmit Phase C error | | 43 | DTE to DCE data underflow | |----------|-------------------------------------------------| | 50-69 | TRANSMIT PHASE D HANGUP CODES | |----------|-------------------------------------------------| | 50 | Unspecified Transmit Phase D error | | 51 | RSPREC error | | 52 | No response to MPS repeated 3 times | | 53 | Invalid response to MPS | | 54 | No response to EOP repeated 3 times | | 55 | Invalid response to EOM | | 56 | No response to EOM repeated 3 times | | 57 | Invalid response to EOM | | 58 | Unable to continue after PIN or PIP | |----------|-------------------------------------------------| | 70-89 | RECEIVE PHASE B HANGUP CODES | |----------|-------------------------------------------------| | 70 | Unspecified Receive Phase B error | | 71 | RSPREC error | | 72 | COMREC error | | 73 | T.30 T2 timeout, expected page not received | | 74 | T.30 T1 timeout after EOM received | |----------|-------------------------------------------------| | 90-99 | RECEIVE PHASE C HANGUP CODES | |----------|-------------------------------------------------| | 90 | Unspecified Receive Phase C error | | 91 | Missing EOL after 5 seconds | | 92 | Unused code | | 93 | DCE to DTE buffer overflow | | 94 | Bad CRC or frame (ECM or BFT modes) | |----------|-------------------------------------------------| | 100-119 | RECEIVE PHASE D HANGUP CODES | |----------|-------------------------------------------------| | 100 | Unspecified Receive Phase D errors | | 101 | RSPREC invalid response received | | 102 | COMREC invalid response received | | 103 | Unable to continue after PIN or PIP | |----------|-------------------------------------------------| | 120-255 | RESERVED CODES | |------------------------------------------------------------| ------------------------------------------------------------- ACKNOWLEDGEMENTS ------------------------------------------------------------- I would like to thank the following people for their assistance during the beta test phase.
