LICENSE IMPORTANT - read the file "LICENSE.txt" for the INTEL SOFTWARE LICENSE AGREEMENT BEFORE COPYING, INSTALLING OR USING. also note: The serial driver open source code located in the directory "serialdrv" is work covered under the GNU GENERAL PUBLIC LICENSE (GPL). The "serialdrv" directory has the GPL in the file "GPL.txt". ------------------------------------------------------------------------------- 2. Release Notes This release supports 2.4.x kernels. This release is not compatible with kernels prior to 2.4. The 536EP corecode binary was compiled with gcc version 2.96 v92 support added: modem on hold AT command set, PCM upstream, v44, and quick connect are implemented. Linux Compatability tests are performed on the latest or previous versions of the following distributions: Mandrake, RedHat, and SuSE ------------------------------------------------------------------------------- 3. INSTALLATION Prerequisites: 1. root access 2. bash shell to run install scripts 3. a 536EP modem 4. KERNEL SOURCE HEADERS FOR THE KERNEL YOU ARE RUNNING (found on your distribution's CD) 6 steps to install 1. login as ROOT 2. extract the archive into a directory with "tar -zxvf <archivename>.tgz" 3. cd into the directory it created. 4. Type: make clean 5. Type: make 536ep 6. Type: make install-536ep 7. When you restart the computer,Tye: bash 536ep-inst The installation script has been designed for the following distributions release versions mandrake-release SuSE-release redhat-release debian_version (including Corel) slackware-version conectiva-version bluepoint-release Unknown distributions install modules and utilities but will not install boot scripts!. Please examine the 536ep-inst script if you have a different distribution. The driver is split in two. A serial driver and core driver. The core driver must be loaded first since the serial driver depends on it. The serial driver registers itself as character device major number 240, minor number 1. The serial driver takes one argument right now, which is a number to override the default major number if you need to. ATTENTION: if the driver compiles but the script just wont work for you. Here are the bare minimum steps to get your modem to work. 0. log in as root. 1. insmod -f 536epcore.o 2. insmod -f 536ep.o 2a. you can start "hamregistry" at this point if you wish. 3. rm /dev/536ep 4. mknod /dev/536ep c 240 1 (note "240" is the default, if it does not work see what /proc/devices says 536ep's major number is) 5. ln -s /dev/536ep /dev/modem 6. start a comm application like minicom and use the modem. 7. see section 3 (International Users) for info on setting the correct country settings. ------------------------------------------------------------------------------- 4. FILE DESCRIPTIONS 536ep-inst installation script to install 536ep modules and supporting files files copied to /lib/modules/(kernel-version)/misc 536epcore.o driver core code module 536ep.o pseudo serial driver for 536ep, depends on 536epcore.o files copied to /etc/rc.d/... (path differes per distribution) 536ep-boot boot scrip to start and stop 536ep modules files copied to /usr/sbin hamregistry hamregistry is the "registry" like tool that the modem uses to get and store persistant data such as county info and profile strings. files copied to /etc hamregistry.bin file that stores the initial persistant data for modem. ------------------------------------------------------------------------------- 5. INTERNATIONAL USERS hamregistry will store the last country setting you set in the modem. in minicom (or equivalent comm application) the commmand to change country setting is "AT+GCI=" the command takes a t.35 country code in hexadecimal. below is a list of currently supported t.35 country codes. you can also put this "AT" command in the init string of the comm application you are using. if you are a CTR-21 country I think you should be able to choose a CTR-21 country on the list and be ok. but that's no guarantee. The same goes for countries that are "USA" compatable. (this table also exist in the source file wwh_dflt.c that ships with the 536epcore driver) country code t.35 code --------------------------- USA 1 B5 KOR 82 61 ECU 593 35 BOL 591 14 CHL 56 15 COL 57 27 PAN 507 85 PER 51 88 SAU 966 98 THA 66 A9 VNM 84 BC SWE 46 A5 DNK 45 31 FIN 358 3C NOR 47 82 ISL 354 52 IRL 353 57 ISR 972 58 LIE 423 68 ESP 34 A0 TUR 90 AE DEU 49 42 AUT 43 0A CHE 41 A6 CYP 357 2D GRC 30 46 ITA 39 59 LUX 352 69 NLD 31 7B GBR 44 B4 BEL 32 0F FRA 33 3D PRT 351 8B PAK 92 84 JPN 81 00 RUS 7 B8 AUS 61 09 MYS 60 6C CHN 86 26 HKG 852 50 SGP 65 9C NZL 64 7E ARG 54 07 BRA 55 16 MEX 52 73 TWN 886 E3 IND 91 53 PHL 63 89 IDN 62 54 BHS 103 0B BRB 104 0E BMU 105 12 GTM 502 49 HTI 509 4E HND 504 4F JAM 1 5B NIC 505 7F PRY 595 87 PRI 121 8C SUR 597 A3 TTO 117 AC URY 598 B7 VEN 58 BB ZWE 263 C4 GUY 592 4D EST 372 E0 HUN 36 51 SVN 386 E2 ARE 971 B3 SVK 421 2E CAN 107 14 CRI 506 1B DOM 110 33 SLV 503 37 GMB 220 41 GIB 350 45 POL 48 8A EGY 20 36 CZE 420 2E ZAF 27 9F GUF 594 E1 ------------------------------------------------------------------------------- 6. Thanks to the following beta testers for their valuable input and suggestions during the HaM 333 beta test between January 2 - 26, 2001 Dorian S. Araneda Sean Walbran Rob Clark Marvin Stodolsky Dominique Duval Roman Krais Ulrich Guenther Marcelino Viana Pinheiro Thomas S. Iversen Jospeh Teichman Michel Bartolone (MED) Ramon Gonzalez Montoiro Ryoji Kawagishi Torsten Vogel "jandro" Ian Carr-de Avelon Helga Weindl Ed Casas Bernhard Hoelcker Alexander "Sasha" Voytov Albert Woo Peter Hirschmann and all of the helpful Linux HaM users around the world and at www.linmodems.org ------------------------------------------------------------------------------- 7. Security issues the 536ep-inst and 536ep-boot file install the files and device nodes as root for the owner and group. this will cause problems for those who want to user the modem to dialout using an account other than root. In SuSE, "dialout" is the group used to install the files and device node. This way, anyone belonging to the "dialout" group can use the modem to dialout. (take a look at /etc/group) I did not want the script to allow full access of the modem to everyone without "root" knowing. Edit the 536ep-boot and 536ep-inst scripts to fit your needs. ------------------------------------------------------------------------------- 8. Compile issues a. this driver will now compile with the this path: /lib/modules/<kernel version>/build/include the 2.4.4+ kernels says to copy the /boot/vmlinuz.version.h over to the kernel build path. I have the makefile do this if this file exists. You must install the kernel source code anyways. It should be on your distribution's CD. ------------------------------------------------------------------------------- 9. What is the Hamregistry? The hamregistery is an application that stores data for the 536ep driver onto the disk. hamregistry stores information from the driver that needs to persist from reboot to reboot such as you current country setting. The 536ep-inst install script and the 536ep-boot script start this utility automatically for you. If this tool is not present when the driver gets used your profile, quickconnect, and current country setting will not be saved but the driver should still work fine. The only step that would need to be done is to make sure that the driver is set to the correct country with at+gci= (see section 5) ------------------------------------------------------------------------------- 10. What's v92 and v44? a. modem on hold: (ISP and your ISP dialer must also support this) This will allow you to pause your ppp connection to answer an incoming call. You will need call waiting, dialer, and ISP support for this to work. When you are done with the call you can resume your ppp connection without having to reconnect. The AT command set for this feature exist in the driver. b, pcm upstream: (ISP must also support this, as of version 4.32 I dont know any ISP's that do) This will allow faster upload speeds. to enable: at+pig=0 to disable: at+pig=1 c. quickconnect: Once you make a call to a v92 modem, your phoneline characteristics are stored. Whenever you make a new v92 connection it will use this data to make the call negotiation quicker (approx 10 seconds). to enable: at+pqc=0 at+pss=0 to disable: at+pss=2 d. v44: (ISP must also support this) A better compression protocol than v42 which can give you better transfer speeds. ------------------------------------------------------------------------------- 11. The Hamregistry tool The hamregistry tool is used to provide persistance of settings across reboots. The haminst and hamboot scripts automatically setup and start the hamregistry background task for the modem to use. The hamregistry tool has command line arguments for those who wish to customize persistant settings. To use these command lines you must first stop the driver with "bash hamboot stop". Once the driver has been stopped you may run hamregistry with one of these arguments to store into the /etc/hamregistry.bin persistance file: (supply value for items in < >) -mfg <Modem manufactures name> -mod <Modem model name> -hookflash <0,1,2> hookflash method: 0=(default)without tone 1=with tone 2=reserved -v92rptopt <0,1> control v92 reporting: 0=PCM upsteam only 1=(default) all v92 -gpio_lpohd <0,1> Handset Hook detection: 0=not supported 1=(default)supported -current_country <t.35 code> This info is written to the /etc/hamregistry.bin file. If hamregistry.bin exists along with the installation files, haminst will copy it to /etc/hamregistry.bin when installing the modem. ------------------------------------------------------------------------------- 12. Known Bugs/Issues a. If you see this message "536ep:rs_open: DSP did not reset. try again or restart computer" and you KNOW you have a HaM modem installed Disable "PNP OS" in your bios. There is a problem with the driver and linux PNP. After a time, Linux PNP will disable the card and the driver currently can not reenable itself. b. Be aware that the build replaces your /lib/module/<kernver>//build/include/linux/version.h file with /boot/vmlinuz.version.h (this is what Linus T. told me to do with a compiler error) c. There may be an incompatibility with DevFS. The 536ep device may be located in /dev/tts/536ep instead of /dev/536ep. Be aware of this and link /dev/modem to the 536ep device that corresponds to your setup. e. Currently there is a problem with the 536ep driver and SuSE 7.2 ppp connections. I have been able to get ppp connection with bellsouth by calling this bash script and wvdial config section: ------my script---------------------- #! /bin/sh /usr/sbin/pppd -detach lock asyncmap 00000000 \ defaultroute debug /dev/modem 57600 \ ipparam ppp0 linkname ppp0 \ noauth \ connect "/usr/bin/wvdial --chat bellsouth" ------my /etc/wvdial.conf section --- [Dialer bellsouth] Modem = /dev/modem Baud = 57600 Init1 = ATZ Inti2 = ATQ0 V1 E1 S0=0 &C1 &D2 Dial Command = ATDT Phone = 6859500 Username = myloginname Password = mysecretpassword #Ask Password = 1 Stupid Mode = 0 ------------------ ------------------------------------------------------------------------------- 13.
