cFos

What's new? 'cFos' ISDN Driver Family ---------------------------------------------------------------- Please read this list of changes and enhancements carefully, because we maybe changed some details that might concern you. To make things a little easier, here's a small legend: * New feature ! Software-change requires modification of your configuration x Bugfix - Information only Revision history: ---------------------------------------------- x Fixed a display bug with the "left" count of the volume budget. x Removed the OID vs. vendor ID check. some ethernet boards were falsely not found (e.g. D-Link). This should be fixed now. cFos/2 x Fixed TRAP 0e when connecting with VJ-compression. cFos/Win 3.81, 15-Jan-2001 cFos/NT 3.81, 15-Jan-2001 * SETUP now adds the "cFos ISDN, Internet, add. Sync PPP over HDLC" automatically if you have ISDN and there is a free COM-port. x The &S3 register is back. cFos/Win 3.80, 05-Jan-2001 cFos/NT 3.80, 05-Jan-2001 cFos/2 3.80, 05-Jan-2001 ! SETUP now automatically installs the Internet ISDN and/or DSL modem on Win98/ME, NT4/Win2k. Just run SETUP, restart and you're ready to go online! ! cFos now has also a volume budget management! Set S96 to the amount of megabytes of volume you have for free and set S93H=1 to activate displaying the volume budget instead of the time budget. Set S93H=2 to display both. Selecting the budget has been changed to S93L=<budget>. ! cFos has a small packet filter: "Poor man's Personal Firewall" It analyzes your incoming and outgoing packets and blocks possible harmful packets. This is designed to be a basic defense against some well-known weaknesses. It does not replace a "real" firewall software like Zonelab's Zonealarm (www.zonelabs.com). cFos inspects your PPP traffic and blocks all unknown protocols. Then it checks your IP traffic and blocks possible harmful ICMP messages and TCP & UDP packets to/from known weak ports. There are 3 security settings: S89 = 1: trusting: only block dangerous port access 3: cautious: block access to low ports 4: paranoid: block access to low ports and block all incoming TCP open Low ports are ports 0-1023, dangerous ports are right now 42, 67, 68, 79, 113 for incoming traffic and 137-139 for both incoming and outgoing traffic. At least cFos protects you from flooding your PC with PINGs and it closes the NETBIOS barn-door, which allows "bad guys" to use your PC's shares and maybe files. If you do not have any servers running that should be accessible from the net, then S89=3 is a good setting. * cFos now monitors the reason why a login failed. If it is due to some congestion on the host side, cFos disconnects the connection by itself, thus preventing Dail-Up Networking from clearing the password from its database. DUN will just tell you that the connection was disconnected and ask you if you'd like to redial. If this doesn't work for you (check back with a CTRACE.TXT file) then you should send us a snippet of CTRACE.TXT and NDISLOG.TXT showing the PAP or CHAP disconnect text. We'll then add this text to a collection of texts we check for so far. Note: this is not a reliable way, just a workaround, but a very convenient one, we think. * Inactivity registers S19, S85 & S86 may now be switched to second resolution by setting S74.7=1. * ATS74.8=1 also disconnects from packet handler in case of inactivity (S19, S85, S86). * Added PPPoE autodetection. By setting S92=255 you select the first PPPoE adapter in your system that can be found by cFos to be used. Typically there is only one PPPoE adapter. If you have more, you can still set them by setting ATS92=<number>, where <number> can be taken from NDISLOG.TXT. * cFos will now switch off the sending of LCP Echo-Req (see S83, S84) if the peer never answered to them. You can switch on the "hard" behaviour (i.e. drop the line even if the peer does not seem to answer Echo-Req's) by setting S74.9=1. * cFos now dumps values that differ from the defaults to the CTRACE.TXT (if enabled) when you do ATZ. Helpful for troubleshooting. * If you want to see the total connection time (instead of the charge count-down timer) even if there is charge info on the line, set S74.10=1. * Added time-budget handling feature: If you set S75.5=1 then the time budget starts counting from the second you login successfully, instead of counting the 'link time'. This way, unseccessful login (e.g. due to congestion) are not counted. This is set by default now only for the DSL modem in MDMCFOS.INF. * The MDMCFOS.INF modem auto-detection has been enhanced: The cFos ports announce themselves to the modem detection as DSL, ISDN sync PPP, add. ISDN sync PPP, in this order. If you don't have DSL, they start right with the ISDN modem, if you don't have ISDN, it's the DSL modem on all ports. * S70 can now be switched to 10th of Cents, Pfennig... Set S74.11=1 to do this. Ex: To set a unit price of 2.9 Pfennig use ATS74.11=1S70=29 x Windows Modems had an inactivity timer of 2 minutes set. This has been fixed; inactivity disconnect is no longer enabled by default. x If &S7 was longer than the PAP username it would not have been appended. This has been fixed. x Default of S75 changed to 128, i.e. PPP wakeup frames are no longer sent by default. This should help some switches/ ISDN boards that like to crash the connection if they receive data too early. x Fixed a bug which could cause GPFs with some CAPIs when used with COM port bytesize of less than 8. x Some cosmetical changes. cFos/Win * cFos/Win now supports ports COM1 up to COM99. If you want to use COM10 and higher, just add "COM10" (or the respective port name) in the parameters line. x Sometimes (e.g. with Installshield) programms would "hang" for about a minute when CFNDIS.EXE was loaded. Fixed. cFos/NT * Added -kr parameter: dynamic register/release. cFos does only register at CAPI when a port is opened and releases CAPI when all ports are closed. This way you may load cFos even if there is no CAPI loaded yet (cool for laptops with PCMCIA cards). Does not yet work with -v0 (CAPI2032.DLL support). If you specify -l3 or higher, -kr will be switched off, because you need to be registered permanently at CAPI to get incoming call notifications. * For the friends of the large status window: we added an option to automatically size the window to the minimum amount of lines needed. This is called "Auto-Size" and it's in the "Window Settings" submenu of the context menu. x Fixed a bug where cFos/NT would "eat up" file handles. Thanks to Maik Reiss for his good bug report. cFos/Win 3.52, 18-Sep-2000 cFos/NT 3.52, 18-Sep-2000 x Fixed a crash at DSL connection start. cFos/NT * CAPI2032.DLL interface became more tolerant to strange CAPIs. x Fixed DSL disconnect delay and crash when disconnecting during a download. cFos/Win 3.51, 03-Aug-2000 cFos/NT 3.51, 03-Aug-2000 cFos/DOS 3.51, 03-Aug-2000 cFos/2 3.51, 03-Aug-2000 ! Support for Austria Globalcall. Calls with empty called party numbers, like with Autria's Globalcall, or empty subaddresses are ignored. If you set S74.4=1 cFos matches such calls with the first MSN/subaddress set in &a0..9. ! Added functionality to the cFos Caller Monitor like playing .WAV files, opening files, executing commands and displaying your own taskbar icons on certain events. This is controlled by a file named CFOS.INI. LOCAL.INI is obsolete now. See a sample CFOS.INI file named SAMPCFOS.INI for more information. Additionally, you can view the last 10 callers in the context menu. * You can now activate the use of the current selected MSN for X.31/X.25 calls by setting bit 5 of register S74. Default is disabled. * Budgets are calculated in minutes by default. By setting S74.6=1 they may be calculated in seconds now, if you like. x Fixed an ERROR/LISTEN that could have been the first data you receive when opening a freshly started cFos. x Fixed slight problems when changing the reset day (S95) of an already used budget. Enhanced AT&G5 display. x Fixed a bug which prevented calls to the packet handler for X.31, case B calls. cFos/Win x Fixed a bug that prevented or delayed data to be written on disk in the context of DSL connections. This affected writing LOGFILE.TXT, accumulated charges and budget data. cFos/NT x Sometimes the clock was corrupted. This has been fixed. x Fixed a memory leak when -v0 was used. x Fixed SETUP32 process which sometimes put a -v in Parameters. * Usually the cFos status window is open after start when the driver part was unable to load (e.g. no CAPI driver found). The -jo parameter starts the status window closed even if the driver did not load. - Changed the SETUP32 process so that you have to boot less under some strange circumstances. - Changed time cFos/NT waits for the CAPI driver to start up from 5 to 10 seconds. Hopefully this fixes problems with ELSA CAPIs. cFos/Win 3.50, 02-Jun-2000 cFos/NT 3.50, 02-Jun-2000 cFos/DOS 3.50, 02-Jun-2000 cFos/2 3.50, 02-Jun-2000 ! New Product: cFos/ATM is a new driver with special Broadband-CAPI / ATM SVC and PVC support! cFos/ATM allows the use of a world of modem applications with broadband networks like ATM. cFos/ATM combines ISDN, ATM and DSL (PPPoE) into one product. cFos/ATM includes licenses for cFos/Win, cFos/NT and cFos/2. It runs with (normal) narrowband CAPI drivers or with broadband CAPI drivers, like the most recent drivers for HST Saphir 2025 and 2155 cards. Many thanks to Joern Bardwyck, again, for the many helpful hints and explanations! We added a special broadband modem register set *S0 to *S14 and two new string registers &S8 / &S9 to allow you to select a great variety of ATM (Q.2931) parameters. Special broadband ATM features are: - cFos treats SVCs like dialup connections with modems or ISDN. - Full ATM protocol- and protocol-parameters selection by evaluating all relevant signaling elements. - Full protocol signalling for outgoing calls. - Max. framesize negotiation according to Q.2931, appendix F.3. - Traffic contracts: CBR, VBR (realtime and non-realtime) with constant or variable bitrates, UBR, UBR+ and ABR (with selection of PCR and MCR). - Provisions for narrowband <-> broadband interworking, by evaluation of narrowband information elements. - Mapping of narrowband listen mask -> broadband listen mask. - User-selectable AAL1 parameters, user-codable BBC values. - Support of CAPI's ATM channel allocation features for PVCs and dedicated VPs/VCs for SVCs, see registers *S8 / *S9 for details. - Support for RFC 2364, PPP over AAL5 incoming and outgoing calls, ie. cFos evaluates / provides the required signalling element. Also LAN LLC encapsulation can be used and signalled. - Support for protocol signalling according to TR 9577. - Support for HST broadband spec. (default) and the current broadband CAPI proposal (use -j$ switch). By providing full signalling support for outgoing calls and evaluation of the respective info elements for incoming calls, we hope that this time a lot of compatibility problems, which exist in ISDN because the signalling elements are not used properly, can be avoided. For a complete documentation of cFos/ATM's additional broadband features see ATM.HTM. ! Removed &P and &U modem commands. Use string registers &S11 and &S12 instead. ! The current ISDN MSN is now used as X.31/X.25 calling party number. Thus you can set your calling number in the same way as with ISDN dial-up connections by settings &Ax and &En. ! Filename changes: CTRACE -> CTRACE.TXT LOGFILE -> LOGFILE.TXT ! The PROFILE data format has changed, old profile data will have to be re-entered and saved again. Sorry for the trouble, but the old system was getting too small. * Speeded PPP dialin in conjunction with MS DialUp-Network. Be sure to turn off IP-Header-Compression under Windows 9x with T-DSL for fast login! Rightclick on your T-DSL connection in Dailup-Network and select Properties -> Server Types -> TCP/IP settings -> IP-Header-Compression and switch it off. Be sure to switch off the Properties -> Server Types -> Logon to Network as well! * Added subaddressing support: You can now dial subadresses by using @ in the phone number or register S115. Also you can listen to subaddresses or combinations of MSNs and subaddresses. For more information see register &S10 (in MODEM.TXT) about simulating MSNs by using subaddresses and SUBADD.HTM for a complete description of cFos' use of MSNs & subaddresses. * Added PPP LAN LLC encapsulation according RFC2364. You can set S75.1=1 to activate it. * Improved detection of some ethernet boards (cFos/Win & cFos/NT). * New nice Icons * Parameter -dtt generates CTRACE.TXT files with 1/100 sec timestamps for cFos/Win and 1/1000 sec timestamps for cFos/NT. * You can specify a CAPI reject cause in Register S38. This can be useful for the Fido Freepoll feature. See MODEM.TXT for more information. * Changed ATD modem command, so that it will no longer need an actual phone number when used with ADSL. * Changed default of register S109 to reflect changes in CAPI 2.0 3rd edition. You can reset it to 127 if you experience problems with older CAPIs (ie. ERROR/LISTEN modem responses). Also registers S41 & S42 are no longer mapped to register S109. Please use S41, S42 for CAPI 1.1 and S109 for CAPI 2.0. * Improved protocol selection for incoming calls. cFos should now be able to handle incoming X.31, Case B calls. * cFos can change your username in outgoing PAP authentication requests. This may be useful e.g. for dialins that require to have a domain part at the end but software that does not support that. There are two ways: -- Set &S6 to the old username and &S7 to the new one. cFos will replace the old one (if found) with the new one. -- Leave &S6 empty and set &S7 to the domain to be added. &S7 will be added to the username if it's not already there. * Now cFos always creates an NDISLOG.TXT file, when used for DSL / PPPoE. It contains information about the last PPPoE session and your ethernet adaptors. It will be overwritten with the next PPPoE login attempt. x Fixed a bug with PPP Echo-Reqs which could cause DSL- disconnects. x Charges wouldn't be displayed in the correct position in the small status window. Fixed. x Sometimes the V.120 protocol would not be selected properly for incoming calls. Fixed. x Fixed a bug where multiple PPP frames where encoded into one HDLC frame. - By default cFos also listens to call of type packet mode and 56k rate adaption and all types of GSM/V.110 calls. Therefore we changed defaults of registers S107 & S14. - Modified CAPI 1.1 to CAPI 2.0 mapping. Changing register S14 will also change S107/S108, changing register S20/S21/S27 will change S100..S103 and changing S16/17 will generate BC,LLC,HLC values and thereby change register &S0..&S2. No other mapping is performed (ie. no mapping on ATZ will occur). - Changes to the statusline: CPS-rates are now like 1234 (up to 9999 cps), then 12k3 (up to 99999 cps) and then like 123k. Online-time counter is now like mm'ss (up to 99min 59sec), then like hh:mm. cFos/NT ! Support for CAPI2032.DLL! SETUP32 will detect if you have no kernelmode CAPI driver and look for a CAPI2032.DLL. If found, it will add the switch -v0. This REQUIRES the status window to be present, i.e. it will NOT work if you're not logged in. You may activate it manually if you have problems with your kernelmode CAPI (eg. API_GET logic startup error or spurious crashes or hangs with network CAPI drivers). Just add -v0 in SETUP32's parameter field. If used and debugging is on (-d.. switch used) the status window will create a CDTRACE.TXT log file. Send this to us if there are problems in our CAPI2032.DLL support. PLEASE send us a mail if CAPI2032.DLL support works better than the 'old' kernelmode support! Please include \WINNT\CFSETUP.LOG in your mail. * Now CAPIs with non-standard names (like DiCapi instead of CAPI20x) are supported. Use -v<name> (like -vDiCapi) to activate it manually. Usually the installer will set the right CAPI name for you. x Fixed freezes of cFos/NT with DSL under Win2000. x Fixed time-sync bug under Win2k. - -jr switch is now default. Use -jj to re-activate CAPI re- registering. cFos/Win - Removed 'Stop Service' context menu selection. Use 'CFOSDW -d' instead. cFos/2 x Fixed slow internet uploads. cFos/NT 3.03 BETA, 09-Feb-2000 ! cFos/NT has now PPPoE (i.e. (A)DSL) support! How to use cFos/NT DSL with Telekom T-DSL: -- Dedicate one cFos COM-port to DSL -- Add the "cFos DSL ..." modem to that port using the Modem manager (Start > Settings > Control Panel > Modems) -- Windows will offer to reconfigure RAS, follow that suggestion. -- Add a RAS port using the cFos DSL modem. -- Finish RAS setup and reboot when you're asked. -- Start Dial-Up Networking and add a new connection. Select the cFos DSL modem and enter an arbitrary phone number (like 42). Save the new entry. -- Click 'Dial' and enter your account data when prompted: It's like "111111111111222222222222#0001@t-online.de". The 1's are your "Anschlusskennung" and the 2's are your "T-Online-Nr.". -- That's it! Have fun with your new high-speed-cFos! Note for WinPoET users: Be sure to Stop the "WinPPPoverEthernet" service in Start > Settings > Control Panel > Services (in German it's under Start > Einstellungen > Systemsteuerung > Dienste). Otherwise, WinPoET will disconnect your cFos/NT PPPoE sessions! It's not enough to close the taskbar icon! * The cFos DSL modems in the .INF file are set to use the budgets 10 (Card 1) and 9 (Card 2). Add the day in the month when your budget is reset by hand in Start > Settings > Control Panel > Modems > cFos DSL modem > Properties > Connection > Advanced by settings the "Extra Settings" to ATS95=<day> S94=<minutes per month for budget>. cFos/Win 3.02a, 22-Dec-1999 x Fixed a bug which caused ADSL disconnects when used in combination with ISDN caller monitor. cFos/Win 3.02, 20-Dec-1999 cFos/NT cFos/DOS cFos/2 * Added a smaller cFos status window. This is now the default. You can select old-style (large window) and new-style (small window) in the context menu. The new window contains the following information: line 1: serial number line 2: charging pulses, cps rate, connection timer line 3: dialed/calling number or budget info line 4: caller monitor There are also 2 indicators, the left moves when a block is received, the right when one is transmitted. By double-clicking the client area of the window you can switch the window's title bar on and off. * Added support for 2 (or more) ethernet cards (ADSL/PPPoE). cFos actually supports up to 10 ethernet cards. You can select the card by ATS92=x. 1=first card, 2=second, ... For convenience we added a second cFos (A)DSL modem to the modem manager for easy selection of the second ethernet card. * cFos now writes the disconnect reason to the LOGFILE if logging is activated. x Fixed modem-information for ADSL. When doing PPPoE cFos now reports 10.000.000 bit/s so that some media players will play broadband stream. - You may experience problems playing broadband streams with windows media player. According to our tests you can solve them by deactivating UDP. Start program files\windows media player\mplayer2.exe and select "view" -> "options" -> "advanced" -> "Windows Media" and deactivate the UDP check box. cFos/Win x Fixed a GPF and some memory problems, which could occur when cFos/Win was used with ADSL only. Thanx to Michael Lau and Oliver Rode. x Fixed a serious bug which could cause all kinds of problems when cFos was loaded without a working CAPI, ie. ADSL only. x Fixed a bug which caused a crash when clicking on "Help!" in the context menu. Thanx to Hans-Georg Joepgen. cFos/Win 3.01, 03-Dec-1999 * Added automatic blocksize adjustment in order to overcome problems with MTU/MRU sizes greater than 1492. x Fixed PPPoE address field handling and a lot of other inconsistancies to RFC2516 and 2 bluescreens when an error occurred during PPPoE session negotiation. Many thanks to Heinz Rickes for his superb bug-reports/traces and helpful hints. x Fixed a bug in RFC1662 conversion which could affect send (but not receive) speed. - Note! In our tests WinPoET interfered with the cFos PPPoE packets by actively trying to disconnect cFos' PPPoE session, therefore you have to shutdown WinPoET before using cFos: right-click on WinPoET's tray icon and select shutdown. cFos/Win 3.00, 25-Nov-1999 cFos/NT 3.00, 25-Nov-1999 cFos/DOS 3.00, 25-Nov-1999 cFos/2 3.00, 25-Nov-1999 .... If you're interested in even older history, get it from our BBS as CFOSHIST.ZIP. ------------------------ End of file ---------------------------
