- GammaLink Frequently Asked Questions v4.0.5, 25 Sep 1995.
-
- This is a list over common problems and questions about GammaLink's
- products. It is based on my experiences with technical support on
- GammaLink products and information from others, support engineers as
- well as customers. I currently work in technical support at Traffic
- Software, Iceland, and has therefore no connection to GammaLink
- other than they are one of the boards supported by our LAN fax
- software, Object-Fax. I will not be held responsible for any errors
- in or misuse of the information contained in this document, nor will
- any one else. I also have an Object-Fax FAQ that can be of interest
- to Object-Fax users.

- Part 1. Comparisons with other products
-
- 1.1 What is GammaFax?
-
- GammaFax is a high-end intelligent fax board for PC compatible
- computers with ISA or MC bus. The GammaFax boards are the most used
- intelligent fax board on the market (according to GammaLink).
-
- 1.2 What is GammaLink?
-
- GammaLink is the company who makes the GammaFax boards. They also
- have other products related to faxing. GammaLink is a wholly owned
- subsidiary of Dialogic, who makes other equipment for computerised
- telephony like voice boards.
-
- 1.3 Ophh, isn't that very expensive?
-
- Yes. The GammaFax board IS expensive compared to fax modems. That is
- because it is an intelligent fax BOARD, not a fax MODEM.
-
- 1.4 So, what's the difference?
-
- Why can't I just use a much cheaper fax modem?
-
- Maybe you can, but if you want your fax communications to be fast,
- reliable and easily expandable, you should really consider
- intelligent fax solutions instead of fax modems. For example, don't
- try to use more than four fax modems on the same PC-computer
- simultaneously. Since fax modems are interrupt driven, there will be
- an enormous amount of interrupts choking the computer. GammaLink has
- support for up to 30 lines in a single computer. It works too, and
- 24 lines send faxes with only 17% processor usage on a 33 MHz 486.
- This is because intelligent fax boards have their own processor and
- memory, which does all the hard work.
-
- I know of only three intelligent fax board makers, GammaLink,
- Brooktrout and PureData. The Intel SatisFAXion line of boards has
- been sold to PureData, who also makes its own line, Faxination.
- SatisFAXion boards are not necessarily intelligent boards. Some of
- them are, but the rest of them are simply internal fax modems with
- CAS drivers. So, if you buy SatisFAXion, be sure that you get the
- intelligent boards. You might also want to check out the I3 third-
- party drivers for SatisFAXion. At least if you are doing multiboard
- faxing. Since I haven't had any experience using Brooktrout, I can't
- say much about these boards.
-
- 1.5 Does GammaFax have a CAS interface?
-
- Yes. There is a file called GCAS.EXE that gives you CAS interface
- support for GammaFax boards. GCAS.EXE is not officially supported by
- GammaLink. It also has a couple of problems. The first one is that
- there is only one official version (1.0), but I have found three
- different EXE files. Microsoft call one of these 1.02, but I'm not
- sure which one. The other problem is that GammaFax boards don't
- support DCX files, which many applications use. You need to use PCX
- files instead, which are supported by both GCAS and other CAS
- implementations.
-
-
-
-
- The I3CAS driver is a third-party driver that works much better. It
- is available from GammaLinks BBS.
-
- 1.6 What's the difference between the GammaFax boards?
-
- There are three basic types of GammaFax boards, XP/CP, XPi/CPi and
- MLCP boards.
-
- The XPi and CPi can be viewed as newer versions of the XP and CP.
- The biggest differences are that the XPi/CPi boards use a removable
- sub-board for the line interface, to simplify manufacturing of
- international versions. The CPi has a couple of extras, like support
- for V.17, the 14.400 BPS fax standard, Error Correction Mode, Group
- 4 compression and built-in DTMF support. The XP/CP line is still
- there because the XPi/CPi line isn't approved in all the countries
- that the XP/CP line is.
-
- With the XP and XPi you can have up to four boards in the same
- computer, but with the CP/CPi you can have up to 16. Also the CP/CPi
- can be used with the real-time interface (see 4.3). The CP and CPi
- boards are available in MicroChannel versions. There is also the
- CPD-board, a version of the CP board made for DID circuits.
-
- The MLCP (MultiLine CP) boards, usually called CP-4, CP-6 or CP-12,
- has four, six or twelve fax channels on each board. The CP-4, come
- in four versions, CP-4/AEB, CP-4/MVIP, CP-4/SC and CP-4/LSI. The
- AEB, MVIP and SC versions have no line interface, instead they use a
- telephony interface (either AEB, MVIP, PEB or SCSA) to talk to other
- boards that have a line interface. This can be used of you have
- voice boards, or if you have a T1 line that you want to use for
- faxing. They can also be used with DID line interfaces. Because of
- this not all combinations of multiline boards and interface boards
- are compatible with the normal CPi board, however if you use one of
- the SC boards together with Dialogics SCSA line interface boards you
- should be able to get full compatibility. I haven't tried this
- myself yet.
-
- The PEB interface is compatible with the SCSA interface, so if you
- are using PEB boards, you should get the SC fax boards. The CP-4/PEB
- board mentioned in some GammaLink version is from my understanding
- just an old name for the CP-4/SC. The board was renamed when SCSA
- accepted PEB as the standard. The CP-6/SC and the CP-12/SC are like
- the CP-4/SC, only with 6 or 12 lines instead of four.
-
- The CP-4/LSI is simply four CPi boards in one, and are fully
- compatible with CPi. It will not be approved in countries requiring
- hardware modifications from the US standards. If you want multiline
- boards with approval in your country, then use the CP-4/SC together
- with the Dialogic LSI line of boards. They are approved in many
- countries.
-
- The newest addition to the GammaFax family is the CP/100 board. It
- is a cute half length board that seems to be exactly like a CPi
- except that it is much smaller and has no speaker. It also has the
- switches and LED's accessible without opening the computer.
-
-
-
-
- 1.7 Can I mix and match GammaFax boards?
-
- No. I have been told that you can mix XP with XPi, and CP with CPi
- boards. You also can mix XPi with CPi, but then you can't use more
- than four channels. You couldn't mix XP with CP boards earlier, but
- that may have changed, but you would still have a four channel
- limitation. If you have XP boards and need to use more than four
- channels you can upgrade your XP/XPi to a CP/CPi. You should be able
- to mix any kind of CP and CPi boards, including the multiline
- boards. You can have up to six multiline CP boards in one computer.
- Two CP-12 and one CP-6 would then give you the maximum of 30 lines!
-
- 1.8 Short summary of features
-
- - Latest version of the GammaFax software is 5.3
- - Intelligent, reliable sending

- - Intelligent queue-handling
- - Application transparent expanding of fax lines
- - Tool kit for DOS, OS/2 and Unix available
- - Up to 30 lines per chassis
- - Most boards support V.17, ECM, MMR & DTMF
- - Network transparency
-
- Part 2. GammaFax XP/CP
-
- 2.1 Install crashes on my 486!
-
- Don't worry. When starting install there's this snazzy graphics part
- that doesn't work on fast computers. Just lower the speed during
- install (by releasing the Turbo button if there is one, otherwise
- you should be able to do it with the BIOS setup), and it will be
- fine. Version 5.2 and later uses a different installation program,
- and doesn't have this problem.
-
- 2.2 Install worked fine, but the software doesn't.
-
- I have a fast 486 with Micro Channel bus.
-
- You'll need a special version of the dispatcher, made for 486's with
- MC-bus. Call your distributor. I BELIEVE, but I'm not sure, that
- this is fixed in versions 5.0 and later.
-
-
-
-
- 2.3 Problems with sending and receiving
-
- 2.3.1 I can't send and/or receive faxes, and I can't find
- anything that's wrong. What should I check?
-
- Start with this:
-
- 1. Check that the wall socket is working by connecting a telephone to
- it and dial somewhere. Please note that in some countries, like
- Norway and Sweden, you can't use the same cord for the telephone
- and the fax modem. The telephones there have often a different
- pin-out than the normal American.
-
- 2. Check that the cord between the wall and the board is connected to
- the upper socket on the fax board, and that the active cords are
- connected to the two connectors in the middle.
-
- 3. In the file GFAX.$DC there is a line 'GFXSHUTDOWN 1 0'. Be sure
- that it really ends with 0. Otherwise the board will just send or
- just receive faxes.
-
- 2.3.2 When I start the GammaFax dispatcher everything seems to
- be OK. However, when I send a fax or try to send one to the GammaFax
- board, the card will pick up the phone but it will not try to
- connect. After that the board seems to 'get stuck', and won't
- respond. Is the card broken?
-
- No, probably not. The most frequent cause for this is that you have
- loaded the wrong binary file to the board. There is two binary
- files, GFXCP.BIN and GFXCX.BIN. GFXCP.BIN are used for ordinary XP-
- and CP-boards, GFXCX.BIN are used for CPi, MLCP and CP boards that
- has a DFX daughter board installed. I would guess XPi uses
- GFXCP.BIN.
-
- 2.3.3 When I look at the queue with the FAX menus the sending
- fax is marked BUSY, but when the board dialled the number I heard
- that it wasn't BUSY. It sounded as the board made a normal
- connection to the receiving fax machine. What's wrong?
-
- Nothing. BUSY doesn't mean that the answering end was busy, that is
- status 3931. BUSY means that the queue record is busy, i.e. being
- processed. It's the normal state for faxes being sent.
-
- 2.3.4 One or several of the faxes in the Queue are 'BUSY' but
- nothing happens. What to do?
-
- This could have several causes. Firstly, the view of the pending
- queue in the fax menus will not be updated unless you exit the view
- and enter it again. If that doesn't help you probably haven't loaded
- the dispatcher. If you have, then the dispatcher may have stopped
- working. Try to reset the queue file with GFQRESET. Now the faxes in
- the queue shouldn't be marked BUSY any longer. If the faxes become
- BUSY again, the dispatcher is up and running, otherwise you have to
- start the dispatcher, or restart you computer. If that STILL doesn't
- help, try to defragment your queue-file.
-
- If the record in the queue-file that is marked BUSY isn't a fax, but
- a font file, defragmentation of the queue-file is the hottest tips I
- have.
-
-
-
-
- 2.4 How can I prevent queue-file fragmentation?
-
- First you should restart the computer without starting the
- dispatcher. Then delete the queue-file. Defragment you hard disk
- with a disk defragmentation utility like Norton's Speedisk. Then
- create a new queue-file with 'GFQRESET -p3 -q2 -rn', where 'n' is
- the number of record you want, say 50. Then run GFQRESET with the
- same parameters every time you restart the computer. If the queue
- file still become fragmented, try increasing the number of records.
-
- 2.5 National character problems
-
- When I'm sending text files my national characters won't appear or
- there will be strange characters instead. Why?
-
- GammaFax will remove all non ASCII characters from text files. That
- way some older and simpler word-processing formats could be sent
- without modification. This means that all characters with ASCII-
- value 127 and above will be removed, as well as all lower than 32.
- Include the line 'GFXEXTEND x y' in your GFAX.$DC file. 'x' is the
- number of the fax board, usually 1, and 'y' should be 1 to include
- characters above 127 or 2 to include all characters. This will make
- your national characters appear. If you are using a code page other
- than 437, they will indeed appear, but not correctly. The default
- fax board font is code page 437, and you have to load a new font to
- the fax board to yield the correct results with other code pages.
- You should be able to receive those fonts from you dealer. I have
- fonts for code pages 437, 850, 862 and 865. There are also fonts
- that use Windows code page, so you can send text files created in
- Windows, and still get your national characters right. If you need
- other code pages than these there are also utilities available for
- creating fonts of your own.
-
- 2.6 I can't start the dispatcher
-
- I received an error message looking like this:
-
- ERROR: Sent 4096 bytes in message, but -3 were consumed by
- driver
- 13:11:18:1: gfdFlushBoard+++ Board has died 1
-
- What's wrong?
-
- Your fax board has too little memory. Starting with v4.4 the
- GammaFax software needs 512KB memory on the GammaFax boards, and
- many older boards only have 256KB. Upgrades are available from your
- dealer.
-
- 2.7 I get strange non-reproducible errors
-
- Any ideas what to do?
-
- Errors that are hard to reproduce might be caused by having a too
- old ROM revision on you GammaFax board. If the ROM is marked with a
- year earlier that 1990 you should contact your retailer to upgrade.
-
-
-
-
- 2.8 Error status 3500
-
- When I send faxes the faxes will get the error status 3500,
- ``GFX_NOTCOMPATIBLE, Queue record ID/ROM ID mismatch.'' What kind of
- stupid status is that?
-
- Some applications demand CP boards, for example Lotus Notes. Using
- those software's with XP boards usually results in this error
- status. There are XP to CP upgrades available from your dealer.
-
- 2.9 Only one page will be sent
-
- When I try to send to a specific fax I always get an error status.
- The recipient says that he receives the first page sent, but not the
- rest. Why can't I send to this fax?
-
- I have experienced this problem with some Swedish fax machines of
- the brand Teli or Televerket. These fax machines do something wrong
- in the handshake between pages. Insert the line 'MODEMCTRL x 1076 1'
- where 'x' is the fax board number, into your GFAX.$DC. It causes the
- fax board to ignore that protocol error and continue. Since I don't
- know of any problem with having that command in the GFAX.$DC file I
- recommend it to everyone in Sweden.
-
- 2.10 Does GammaFax work with Windows?
-
- Yes, and no. Windows is an inherently unstable environment in some
- ways. Amongst all the things it does is a lot of so called 'context-
- switches'. Occasionally a context-switch may not be advertised
- properly by Windows, and which will cause the GammaFax dispatcher
- (and much other software) to crash. The result of this is that if
- you start the GammaFax dispatcher, Windows will crash somewhat more
- often, about once a week according to people who tried this. A
- normal Windows installation would crash a couple of times a week in
- any case, so the difference might not be that big. Best way to get
- rid of this problem is to put the board in a PC not running Windows
- and move the queue-file to the network. If you have to run Windows
- on the computer with the GammaFax boards, exit Windows when you're
- not using it. Otherwise, it works fine. Using a fax modem is not a
- solution, since this will cause more trouble that the GammaFax
- boards would, just different trouble.
-
- My limited testing of GammaFax and Windows 95 indicates that the
- GammaFax dispatcher doesn't work if you load it from AUTOEXEC.BAT.
- Loading it in a DOS-box seems to work though. If you only run the
- dispatcher you can run it in foreground mode in a DOS-box. If you
- also run some other DOS-software you could probably load the
- dispatcher in background mode in the same DOS-box as the other
- software.
-
- Part 3. GammaNet/Networks
-
- 3.1 How can I use my GammaFax board from a network?
-
- Since the GammaFax boards work well on networks, you don't actually
- need anything extra. But the GammaFax software included with the
- boards don't have any support for sending faxes from inside
- applications. That is what most people want from their network fax.
- There are lots of different software to do this, both for DOS,
- Windows and OS/2.
-
-
-
-
- A good bet is to use the software of a GammaLink Fax Server partner.
- GammaLink knows who these are, so call them or call your GammaLink
- distributor.
-
- 3.2 My fax board doesn't send when my network is started
-
- What can I do?
-
- You probably are using Novell NetWare, right? Be sure that you start
- the network software before the GammaFax dispatcher, GFDCP.EXE.
- NetWares NETX.EXE does much great magic when it starts, but that
- magic will unfortunately disrupt the GammaFax software. Although I
- only know about this kind of problem with NetWare, It is recommended
- for all networks to load the network before the GammaFax software.
-
- 3.3 Sending from another computer in the network.
-
- The dispatcher will work with the network software loaded, but I put
- the GammaFax queue file GFAX.$QU on a network server, so I can reach
- it from other network stations, or use it with network software
- (cc:Mail, GammaNet, Object-Fax, etc.). It works if I send a fax from
- the computer with the fax board, but not if I send it from somewhere
- else. This ought to work, isn't GammaFax network transparent?
-
- Yes, it is. Just make sure that you have set the time correctly on
- all the computers that are using GammaFax. Every fax sent will be
- marked with a time and date so you can delay sending to later. If
- you don't set a time and date, it will be marked with the current
- time and date. So, if the computer used as a fax gateway is a week
- behind the computer from where the fax was put into the queue, the
- fax will not be sent until next week. Utilities for time
- synchronising are usually included with your network.
-
- Also, don't forget that the file that you send has to be available
- from the fax gateway with the same path and name as from your
- computer. You can't send the file C:\FOOBAR\FROTZ.TXT, since C: is
- your local hard disk. The fax gateway will then look for the file on
- its own local hard disk. You have to copy the file to a network
- drive that is common for both your computer and the gateway. If you
- have GammaNet, it includes a utility called FAXN. It is a modified
- FAXM that will do the necessary copying automatically.
-
- 3.4 Problems with LAN Manager or LAN Server
-
- I have set up a fax gateway on my LAN Manager or LAN Server network,
- but the dispatcher will stop working very often. What should I do?
-
- There has been some problem with using the GammaFax DOS dispatcher
- on LAN Manager and LAN Manager derivatives. This is fixed in version
- 5.0 and later of the dispatcher, but if you still experience this
- problem there's an easy way out. Get the OS/2 version of the
- dispatcher from your dealer, and install the fax board in your LAN
- Manager server. Since the OS/2 version doesn't have this problem the
- system should now be more stable. If not, then the GammaFax software
- wasn't the problem. You might also want to try the GFDSHIELD command
- used to fix problems with Banyan Vines.
-
-
-
-
- 3.5 Problems with Banyan Vines
-
- I have problems similar to the LAN Manager problem above, but I have
- Banyan Vines. Will 5.1 fix those problems?
-
- Yes, with version 5.1 features a new undocumented configuration
- command, GFDSHIELD. Try to insert a line first in the GFAX.$DC file
- like this:
-
- GFDSHIELD 0xnn
-
- Where nn is the software vector for the hardware interrupt your
- network card is using, according to this table:
-
- IRQ Vector IRQ Vector
- 2 0A 9 71
- 3 0B 10 72
- 4 0C 11 73
- 5 0D 12 74
- 6 0E 13 75
- 7 0F 14 76
- 8 70 15 77
-
- Part 4. GammaFax development
-
- 4.1 GPI vs. CAS
-
- GammaFax supports two interfaces, the GammaFax GPI and Intel CAS.
- Which should I use?
-
- It depends on what you're after. The GPI is a much better API and
- gives you much better control over the faxes and the fax sending.
- Using the GPI will also lessen the overhead needed since there will
- be no CAS to GammaFax queue conversion.
-
- CAS, on the other hand, doesn't restrain you to use only GammaLink
- boards. In a way it is a choice between high and low end. CAS
- enables your customers to use cheaper boards, the GPI gives you the
- high performance and reliability you want. However, the GammaFax CAS
- interface isn't officially supported by GammaLink.
-
- See also 1.5
-
- 4.2 GPI and XP boards
-
- It says that applications developed with the GPI can't use the
- cheaper XP boards. Why not?
-
- Actually you CAN use the XP board with GPI developed applications,
- but it wasn't officially supported before version 5.1 of the
- GammaFax software. Since both the XP and CP boards talks to the
- queue file in the same manner, the application putting records into
- the queue file aren't aware of what kind of card that is actually
- used. Therefore you can use XP boards without any problems, as long
- as you are only communicating with the boards through the queue
- file. That is the normal way to do things, so don't worry. However,
- with the GPI you have another option, you can use the real-time
- interface to talk to the boards. This didn't work with XP and XPi
- boards before version 5.1.
-
-
-
-
- 4.3 What is the real-time interface?
-
- Usually you communicate with the fax boards via the queue file using
- the GFD functions. This usually causes a couple of seconds of
- delays. With the real time interface you get closer control over the
- sending through real-time status information. This might be useful
- in certain situations, but it does make things more complicated, and
- using the real time interface might prevent you from using the
- cheaper XP boards. It also means that you have to run your software
- in the same computer as the GammaFax dispatcher. Usually not a
- problem, but it is one of the nice features of the GammaLink API
- that you have complete transparency of OS, networks and number of
- boards, which you will lose when using the real-time interface.
-
- The real-time interface is made up by the GFD and GFV functions. You
- should also beware that the real-time interface changed between 5.0
- and 5.1. Applications using the real-time interface compiled with
- the 5.0 GPI will not work with the 5.1 dispatcher, and vice versa.
