1 | GigaSet 307x Device Driver | ||
2 | ========================== | ||
3 | |||
4 | 1. Requirements | ||
5 | ------------ | ||
6 | 1.1. Hardware | ||
7 | -------- | ||
8 | This release supports the connection of the Gigaset 307x/417x family of | ||
9 | ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB | ||
10 | connection. The following devices are reported to be compatible: | ||
11 | 307x/417x: | ||
12 | Gigaset SX255isdn | ||
13 | Gigaset SX353isdn | ||
14 | Sinus 45 [AB] isdn (Deutsche Telekom) | ||
15 | Sinus 721X/XA | ||
16 | Vox Chicago 390 ISDN (KPN Telecom) | ||

20 | Gigaset USB Adapter DECT | ||
21 | Sinus 45 Data 2 (Telekom) | ||
22 | Sinus 721 data | ||
23 | Chicago 390 USB (KPN) | ||
24 | See also http://www.erbze.info/sinus_gigaset.htm and | ||
25 | http://gigaset307x.sourceforge.net/ | ||
26 | |||
27 | We had also reports from users of Gigaset M105 who could use the drivers | ||
28 | with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.4.) | ||
29 | If you have another device that works with our driver, please let us know. | ||
30 | For example, Gigaset SX205isdn/Sinus 721 X SE and Gigaset SX303isdn bases | ||
31 | are just versions without answering machine of models known to work, so | ||
32 | they should work just as well; but so far we are lacking positive reports | ||
33 | on these. | ||
34 | |||
35 | Chances of getting an USB device to work are good if the output of | ||
36 | lsusb | ||
37 | at the command line contains one of the following: | ||
38 | ID 0681:0001 | ||
39 | ID 0681:0002 | ||
40 | ID 0681:0009 | ||
41 | ID 0681:0021 | ||
42 | ID 0681:0022 | ||
43 | |||
44 | 1.2. Software | ||
45 | -------- | ||
46 | The driver works with ISDN4linux and so can be used with any software | ||
47 | which is able to use ISDN4linux for ISDN connections (voice or data). | ||
48 | CAPI4Linux support is planned but not yet available. | ||
49 | |||
50 | There are some user space tools available at | ||
51 | http://sourceforge.net/projects/gigaset307x/ | ||
52 | which provide access to additional device specific functions like SMS, | ||
53 | phonebook or call journal. | ||
54 | |||
55 | |||
56 | 2. How to use the driver | ||
57 | --------------------- | ||
58 | 2.1. Modules | ||
59 | ------- | ||
60 | To get the device working, you have to load the proper kernel module. You | ||
61 | can do this using | ||
62 | modprobe modulename | ||
63 | where modulename is usb_gigaset (M105) or bas_gigaset (direct USB | ||
64 | connection to the base). | ||
65 | |||
66 | 2.2. Device nodes for user space programs | ||
67 | ------------------------------------ | ||
68 | The device can be accessed from user space (eg. by the user space tools | ||
69 | mentioned in 1.2.) through the device nodes: | ||
70 | |||
71 | - /dev/ttyGU0 for M105 (USB data boxes) | ||
72 | - /dev/ttyGB0 for the base driver (direct USB connection) | ||
73 | |||
74 | You can also select a "default device" which is used by the frontends when | ||
75 | no device node is given as parameter, by creating a symlink /dev/ttyG to | ||
76 | one of them, eg.: | ||
77 | |||
78 | ln -s /dev/ttyGB0 /dev/ttyG | ||
79 | |||
80 | 2.3. ISDN4linux | ||
81 | ---------- | ||
82 | This is the "normal" mode of operation. After loading the module you can | ||
83 | set up the ISDN system just as you'd do with any ISDN card. | ||
84 | Your distribution should provide some configuration utility. | ||
85 | If not, you can use some HOWTOs like | ||
86 | http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html | ||
87 | If this doesn't work, because you have some recent device like SX100 where | ||
88 | debug output (see section 3.2.) shows something like this when dialing | ||
89 | CMD Received: ERROR | ||
90 | Available Params: 0 | ||
91 | Connection State: 0, Response: -1 | ||
92 | gigaset_process_response: resp_code -1 in ConState 0 ! | ||
93 | Timeout occurred | ||
94 | you might need to use unimodem mode: | ||
95 | |||
96 | 2.4. Unimodem mode | ||
97 | ------------- | ||
98 | This is needed for some devices [e.g. SX100] as they have problems with | ||
99 | the "normal" commands. | ||
100 | |||
101 | If you have installed the command line tool gigacontr, you can enter | ||
102 | unimodem mode using | ||
103 | gigacontr --mode unimodem | ||
104 | You can switch back using | ||
105 | gigacontr --mode isdn | ||
106 | |||
107 | You can also load the driver using e.g. | ||
108 | modprobe usb_gigaset startmode=0 | ||
109 | to prevent the driver from starting in "isdn4linux mode". | ||
110 | |||
111 | In this mode the device works like a modem connected to a serial port | ||
112 | (the /dev/ttyGU0, ... mentioned above) which understands the commands | ||
113 | ATZ init, reset | ||
114 | => OK or ERROR | ||
115 | ATD | ||
116 | ATDT dial | ||
117 | => OK, CONNECT, | ||
118 | BUSY, | ||
119 | NO DIAL TONE, | ||
120 | NO CARRIER, | ||
121 | NO ANSWER | ||
122 | <pause>+++<pause> change to command mode when connected | ||
123 | ATH hangup | ||
124 | |||
125 | You can use some configuration tool of your distribution to configure this | ||
126 | "modem" or configure pppd/wvdial manually. There are some example ppp | ||
127 | configuration files and chat scripts in the gigaset-VERSION/ppp directory. | ||
128 | Please note that the USB drivers are not able to change the state of the | ||
129 | control lines (the M105 driver can be configured to use some undocumented | ||
130 | control requests, if you really need the control lines, though). This means | ||
131 | you must use "Stupid Mode" if you are using wvdial or you should use the | ||
132 | nocrtscts option of pppd. | ||
133 | You must also assure that the ppp_async module is loaded with the parameter | ||
134 | flag_time=0. You can do this e.g. by adding a line like | ||
135 | |||
136 | options ppp_async flag_time=0 | ||
137 | |||
138 | to /etc/modprobe.conf. If your distribution has some local module | ||
139 | configuration file like /etc/modprobe.conf.local, | ||
140 | using that should be preferred. | ||
141 | |||
142 | 2.5. Call-ID (CID) mode | ||
143 | ------------------ | ||
144 | Call-IDs are numbers used to tag commands to, and responses from, the | ||
145 | Gigaset base in order to support the simultaneous handling of multiple | ||
146 | ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem | ||
147 | mode"). Without Call-IDs (in Unimodem mode), only a very limited set of | ||
148 | functions is available. It allows outgoing data connections only, but | ||
149 | does not signal incoming calls or other base events. | ||
150 | |||
151 | DECT cordless data devices (M10x) permanently occupy the cordless | ||
152 | connection to the base while Call-IDs are activated. As the Gigaset | ||
153 | bases only support one DECT data connection at a time, this prevents | ||
154 | other DECT cordless data devices from accessing the base. | ||
155 | |||
156 | During active operation, the driver switches to the necessary mode | ||
157 | automatically. However, for the reasons above, the mode chosen when | ||
158 | the device is not in use (idle) can be selected by the user. | ||
159 | - If you want to receive incoming calls, you can use the default | ||
160 | settings (CID mode). | ||
161 | - If you have several DECT data devices (M10x) which you want to use | ||
162 | in turn, select Unimodem mode by passing the parameter "cidmode=0" to | ||
163 | the driver ("modprobe usb_gigaset cidmode=0" or modprobe.conf). | ||
164 | |||
165 | If you want both of these at once, you are out of luck. | ||
166 | |||
167 | You can also use /sys/module/<name>/parameters/cidmode for changing | ||
168 | the CID mode setting (<name> is usb_gigaset or bas_gigaset). | ||
169 | |||
170 | |||
171 | 3. Troubleshooting | ||
172 | --------------- | ||
173 | 3.1. Solutions to frequently reported problems | ||
174 | ----------------------------------------- | ||
175 | Problem: | ||
176 | You have a slow provider and isdn4linux gives up dialing too early. | ||
177 | Solution: | ||
178 | Load the isdn module using the dialtimeout option. You can do this e.g. | ||
179 | by adding a line like | ||
180 | |||
181 | options isdn dialtimeout=15 | ||
182 | |||
183 | to /etc/modprobe.conf. If your distribution has some local module | ||
184 | configuration file like /etc/modprobe.conf.local, | ||
185 | using that should be preferred. | ||
186 | |||
187 | Problem: | ||
188 | Your isdn script aborts with a message about isdnlog. | ||
189 | Solution: | ||
190 | Try deactivating (or commenting out) isdnlog. This driver does not | ||
191 | support it. | ||
192 | |||
193 | Problem: | ||
194 | You have two or more DECT data adapters (M101/M105) and only the | ||
195 | first one you turn on works. | ||
196 | Solution: | ||
197 | Select Unimodem mode for all DECT data adapters. (see section 2.4.) | ||
198 | |||
199 | 3.2. Telling the driver to provide more information | ||
200 | ---------------------------------------------- | ||
201 | Building the driver with the "Gigaset debugging" kernel configuration | ||
202 | option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional | ||
203 | information useful for debugging. | ||
204 | |||
205 | You can control the amount of debugging information the driver produces by | ||
206 | writing an appropriate value to /sys/module/gigaset/parameters/debug, e.g. | ||
207 | echo 0 > /sys/module/gigaset/parameters/debug | ||
208 | switches off debugging output completely, | ||
209 | echo 0x10a020 > /sys/module/gigaset/parameters/debug | ||
210 | enables the standard set of debugging output messages. These values are | ||
211 | bit patterns where every bit controls a certain type of debugging output. | ||
212 | See the constants DEBUG_* in the source file gigaset.h for details. | ||
213 | |||
214 | The initial value can be set using the debug parameter when loading the | ||
215 | module "gigaset", e.g. by adding a line | ||
216 | options gigaset debug=0 | ||
217 | to /etc/modprobe.conf, ... | ||
218 | |||
219 | Generated debugging information can be found | ||
220 | - as output of the command | ||
221 | dmesg | ||
222 | - in system log files written by your syslog daemon, usually | ||
223 | in /var/log/, e.g. /var/log/messages. | ||
224 | |||
225 | 3.3. Reporting problems and bugs | ||
226 | --------------------------- | ||
227 | If you can't solve problems with the driver on your own, feel free to | ||
228 | use one of the forums, bug trackers, or mailing lists on | ||
229 | http://sourceforge.net/projects/gigaset307x | ||
230 | or write an electronic mail to the maintainers. | ||
231 | |||
232 | Try to provide as much information as possible, such as | ||
233 | - distribution | ||
234 | - kernel version (uname -r) | ||
235 | - gcc version (gcc --version) | ||
236 | - hardware architecture (uname -m, ...) | ||
237 | - type and firmware version of your device (base and wireless module, | ||
238 | if any) | ||
239 | - output of "lsusb -v" (if using an USB device) | ||
240 | - error messages | ||
241 | - relevant system log messages (it would help if you activate debug | ||
242 | output as described in 3.2.) | ||
243 | |||
244 | For help with general configuration problems not specific to our driver, | ||
245 | such as isdn4linux and network configuration issues, please refer to the | ||
246 | appropriate forums and newsgroups. | ||
247 | |||
248 | 3.4. Reporting problem solutions | ||
249 | --------------------------- | ||
250 | If you solved a problem with our drivers, wrote startup scripts for your | ||
251 | distribution, ... feel free to contact us (using one of the places | ||
252 | mentioned in 3.3.). We'd like to add scripts, hints, documentation | ||
253 | to the driver and/or the project web page. | ||

15 | * new data and mark it dirty and add the page into a BIO which | ||
16 | * is then written out. | ||
