Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

17 | 1. Introduction | ||
18 | |||
19 | The Smartio family Linux driver, Ver. 1.1, supports following multiport | ||
20 | boards. | ||
21 | |||
22 | -C104P/H/HS, C104H/PCI, C104HS/PCI, CI-104J 4 port multiport board. | ||
23 | -C168P/H/HS, C168H/PCI 8 port multiport board. | ||
24 | |||
25 | This driver has been modified a little and cleaned up from the Moxa | ||
26 | contributed driver code and merged into Linux 2.2.14pre. In particular | ||
27 | official major/minor numbers have been assigned which are different to | ||
28 | those the original Moxa supplied driver used. | ||
29 | |||
30 | This driver and installation procedure have been developed upon Linux Kernel | ||
31 | 2.2.5 and backward compatible to 2.0.3x. This driver supports Intel x86 and | ||
32 | Alpha hardware platform. In order to maintain compatibility, this version | ||
33 | has also been properly tested with RedHat, OpenLinux, TurboLinux and | ||
34 | S.u.S.E Linux. However, if compatibility problem occurs, please contact | ||
35 | Moxa at support@moxa.com.tw. | ||
36 | |||
37 | In addition to device driver, useful utilities are also provided in this | ||
38 | version. They are | ||
39 | - msdiag Diagnostic program for detecting installed Moxa Smartio boards. | ||
40 | - msmon Monitor program to observe data count and line status signals. | ||
41 | - msterm A simple terminal program which is useful in testing serial | ||
42 | ports. | ||
43 | - io-irq.exe Configuration program to setup ISA boards. Please note that | ||
44 | this program can only be executed under DOS. | ||
45 | |||
46 | All the drivers and utilities are published in form of source code under | ||
47 | GNU General Public License in this version. Please refer to GNU General | ||
48 | Public License announcement in each source code file for more detail. | ||
49 | |||
50 | In Moxa's ftp sites, you may always find latest driver at | ||
51 | ftp://ftp.moxa.com or ftp://ftp.moxa.com.tw. | ||
52 | |||
53 | This version of driver can be installed as Loadable Module (Module driver) | ||
54 | or built-in into kernel (Static driver). You may refer to following | ||
55 | installation procedure for suitable one. Before you install the driver, | ||
56 | please refer to hardware installation procedure in the User's Manual. | ||
57 | |||
58 | We assume the user should be familiar with following documents. | ||
59 | - Serial-HOWTO | ||
60 | - Kernel-HOWTO | ||
61 | |||
62 | ----------------------------------------------------------------------------- | ||
63 | 2. System Requirement | ||
64 | - Hardware platform: Intel x86 or Alpha machine | ||
65 | - Kernel version: 2.0.3x or 2.2.x | ||
66 | - gcc version 2.72 or later | ||
67 | - Maximum 4 boards can be installed in combination | ||
68 | |||
69 | ----------------------------------------------------------------------------- | ||
70 | 3. Installation | ||
71 | |||
72 | 3.1 Hardware installation | ||
73 | |||
74 | There are two types of buses, ISA and PCI, for Smartio family multiport | ||
75 | board. | ||
76 | |||
77 | ISA board | ||
78 | --------- | ||
79 | You'll have to configure CAP address, I/O address, Interrupt Vector | ||
80 | as well as IRQ before installing this driver. Please refer to hardware | ||
81 | installation procedure in User's Manual before proceed any further. | ||
82 | Please make sure the JP1 is open after the ISA board is set properly. | ||
83 | |||
84 | PCI board | ||
85 | --------- | ||
86 | You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict | ||
87 | with other ISA devices. Please refer to hardware installation | ||
88 | procedure in User's Manual in advance. | ||
89 | |||
90 | IRQ Sharing | ||
91 | ----------- | ||
92 | Each port within the same multiport board shares the same IRQ. Up to | ||
93 | 4 Moxa Smartio Family multiport boards can be installed together on | ||
94 | one system and they can share the same IRQ. | ||
95 | |||
96 | 3.2 Driver files and device naming convention | ||
97 | |||
98 | The driver file may be obtained from ftp, CD-ROM or floppy disk. The | ||
99 | first step, anyway, is to copy driver file "mxser.tgz" into specified | ||
100 | directory. e.g. /moxa. The execute commands as below. | ||
101 | |||
102 | # cd /moxa | ||
103 | # tar xvf /dev/fd0 | ||
104 | or | ||
105 | # cd /moxa | ||
106 | # cp /mnt/cdrom/<driver directory>/mxser.tgz . | ||
107 | # tar xvfz mxser.tgz | ||
108 | |||
109 | You may find all the driver and utilities files in /moxa/mxser. | ||
110 | Following installation procedure depends on the model you'd like to | ||
111 | run the driver. If you prefer module driver, please refer to 3.3. | ||
112 | If static driver is required, please refer to 3.4. | ||
113 | |||
114 | Dialin and callout port | ||
115 | ----------------------- | ||
116 | This driver remains traditional serial device properties. There're | ||
117 | two special file name for each serial port. One is dial-in port | ||
118 | which is named "ttyMxx". For callout port, the naming convention | ||
119 | is "cumxx". | ||
120 | |||
121 | Device naming when more than 2 boards installed | ||
122 | ----------------------------------------------- | ||
123 | Naming convention for each Smartio multiport board is pre-defined | ||
124 | as below. | ||
125 | |||
126 | Board Num. Dial-in Port Callout port | ||
127 | 1st board ttyM0 - ttyM7 cum0 - cum7 | ||
128 | 2nd board ttyM8 - ttyM15 cum8 - cum15 | ||
129 | 3rd board ttyM16 - ttyM23 cum16 - cum23 | ||
130 | 4th board ttyM24 - ttym31 cum24 - cum31 | ||
131 | |||
132 | Board sequence | ||
133 | -------------- | ||
134 | This driver will activate ISA boards according to the parameter set | ||
135 | in the driver. After all specified ISA board activated, PCI board | ||
136 | will be installed in the system automatically driven. | ||
137 | Therefore the board number is sorted by the CAP address of ISA boards. | ||
138 | For PCI boards, their sequence will be after ISA boards and C168H/PCI | ||
139 | has higher priority than C104H/PCI boards. | ||
140 | |||
141 | 3.3 Module driver configuration | ||
142 | Module driver is easiest way to install. If you prefer static driver | ||
143 | installation, please skip this paragraph. | ||
144 | 1. Find "Makefile" in /moxa/mxser, then run | ||
145 | |||
146 | # make install | ||
147 | |||
148 | The driver files "mxser.o" and utilities will be properly compiled | ||
149 | and copied to system directories respectively.Then run | ||
150 | |||
151 | # insmod mxser | ||
152 | |||
153 | to activate the modular driver. You may run "lsmod" to check | ||
154 | if "mxser.o" is activated. | ||
155 | |||
156 | 2. Create special files by executing "msmknod". | ||
157 | # cd /moxa/mxser/driver | ||
158 | # ./msmknod | ||
159 | |||
160 | Default major numbers for dial-in device and callout device are | ||
161 | 174, 175. Msmknod will delete any special files occupying the same | ||
162 | device naming. | ||
163 | |||
164 | 3. Up to now, you may manually execute "insmod mxser" to activate | ||
165 | this driver and run "rmmod mxser" to remove it. However, it's | ||
166 | better to have a boot time configuration to eliminate manual | ||
167 | operation. | ||
168 | Boot time configuration can be achieved by rc file. Run following | ||
169 | command for setting rc files. | ||
170 | |||
171 | # cd /moxa/mxser/driver | ||
172 | # cp ./rc.mxser /etc/rc.d | ||
173 | # cd /etc/rc.d | ||
174 | |||
175 | You may have to modify part of the content in rc.mxser to specify | ||
176 | parameters for ISA board. Please refer to rc.mxser for more detail. | ||
177 | Find "rc.serial". If "rc.serial" doesn't exist, create it by vi. | ||
178 | Add "rc.mxser" in last line. Next, open rc.local by vi | ||
179 | and append following content. | ||
180 | |||
181 | if [ -f /etc/rc.d/rc.serial ]; then | ||
182 | sh /etc/rc.d/rc.serial | ||
183 | fi | ||
184 | |||
185 | 4. Reboot and check if mxser.o activated by "lsmod" command. | ||
186 | 5. If you'd like to drive Smartio ISA boards in the system, you'll | ||
187 | have to add parameter to specify CAP address of given board while | ||
188 | activating "mxser.o". The format for parameters are as follows. | ||
189 | |||
190 | insmod mxser ioaddr=0x???,0x???,0x???,0x??? | ||
191 | | | | | | ||
192 | | | | +- 4th ISA board | ||
193 | | | +------ 3rd ISA board | ||
194 | | +------------ 2nd ISA board | ||
195 | +------------------- 1st ISA board | ||
196 | |||
197 | 3.4 Static driver configuration | ||
198 | |||
199 | 1. Create link | ||
200 | # cd /usr/src/linux/drivers/char | ||
201 | # ln -s /moxa/mxser/driver/mxser.c mxser.c | ||
202 | |||
203 | 2. Add CAP address list for ISA boards | ||
204 | In module mode, the CAP address for ISA board is given by | ||
205 | parameter. In static driver configuration, you'll have to | ||
206 | assign it within driver's source code. If you will not | ||
207 | install any ISA boards, you may skip to next portion. | ||
208 | The instructions to modify driver source code are as | ||
209 | below. | ||
210 | a. # cd /moxa/mxser/driver | ||
211 | # vi mxser.c | ||
212 | b. Find the array mxserBoardCAP[] as below. | ||
213 | |||
214 | static int mxserBoardCAP[] | ||
215 | = {0x00, 0x00, 0x00, 0x00}; | ||
216 | |||
217 | c. Change the address within this array using vi. For | ||
218 | example, to driver 2 ISA boards with CAP address | ||
219 | 0x280 and 0x180 as 1st and 2nd board. Just to change | ||
220 | the source code as follows. | ||
221 | |||
222 | static int mxserBoardCAP[] | ||
223 | = {0x280, 0x180, 0x00, 0x00}; | ||
224 | |||
225 | 3. Modify tty_io.c | ||
226 | # cd /usr/src/linux/drivers/char/ | ||
227 | # vi tty_io.c | ||
228 | Find pty_init(), insert "mxser_init()" as | ||
229 | |||
230 | pty_init(); | ||
231 | mxser_init(); | ||
232 | |||
233 | 4. Modify tty.h | ||
234 | # cd /usr/src/linux/include/linux | ||
235 | # vi tty.h | ||
236 | Find extern int tty_init(void), insert "mxser_init()" as | ||
237 | |||
238 | extern int tty_init(void); | ||
239 | extern int mxser_init(void); | ||
240 | |||
241 | 5. Modify Makefile | ||
242 | # cd /usr/src/linux/drivers/char | ||
243 | # vi Makefile | ||
244 | Find L_OBJS := tty_io.o ...... random.o, add | ||
245 | "mxser.o" at last of this line as | ||
246 | L_OBJS := tty_io.o ....... mxser.o | ||
247 | |||
248 | 6. Rebuild kernel | ||
249 | The following are for Linux kernel rebuilding,for your reference only. | ||
250 | For appropriate details, please refer to the Linux document. | ||
251 | |||
252 | If 'lilo' utility is installed, please use 'make zlilo' to rebuild | ||
253 | kernel. If 'lilo' is not installed, please follow the following steps. | ||
254 | |||
255 | a. cd /usr/src/linux | ||
256 | b. make clean /* take a few minutes */ | ||
257 | c. make bzImage /* take probably 10-20 minutes */ | ||
258 | d. Backup original boot kernel. /* optional step */ | ||
259 | e. cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz | ||
260 | f. Please make sure the boot kernel (vmlinuz) is in the | ||
261 | correct position. If you use 'lilo' utility, you should | ||
262 | check /etc/lilo.conf 'image' item specified the path | ||
263 | which is the 'vmlinuz' path, or you will load wrong | ||
264 | (or old) boot kernel image (vmlinuz). | ||
265 | g. chmod 400 /vmlinuz | ||
266 | h. lilo | ||
267 | i. rdev -R /vmlinuz 1 | ||
268 | j. sync | ||
269 | |||
270 | Note that if the result of "make zImage" is ERROR, then you have to | ||
271 | go back to Linux configuration Setup. Type "make config" in directory | ||
272 | /usr/src/linux or "setup". | ||
273 | |||
274 | Since system include file, /usr/src/linux/include/linux/interrupt.h, | ||
275 | is modified each time the MOXA driver is installed, kernel rebuilding | ||
276 | is inevitable. And it takes about 10 to 20 minutes depends on the | ||
277 | machine. | ||
278 | |||
279 | 7. Make utility | ||
280 | # cd /moxa/mxser/utility | ||
281 | # make install | ||
282 | |||
283 | 8. Make special file | ||
284 | # cd /moxa/mxser/driver | ||
285 | # ./msmknod | ||
286 | |||
287 | 9. Reboot | ||
288 | |||
289 | 3.5 Custom configuration | ||
290 | Although this driver already provides you default configuration, you | ||
291 | still can change the device name and major number.The instruction to | ||
292 | change these parameters are shown as below. | ||
293 | |||
294 | Change Device name | ||
295 | ------------------ | ||
296 | If you'd like to use other device names instead of default naming | ||
297 | convention, all you have to do is to modify the internal code | ||
298 | within the shell script "msmknod". First, you have to open "msmknod" | ||
299 | by vi. Locate each line contains "ttyM" and "cum" and change them | ||
300 | to the device name you desired. "msmknod" creates the device names | ||
301 | you need next time executed. | ||
302 | |||
303 | Change Major number | ||
304 | ------------------- | ||
305 | If major number 30 and 35 had been occupied, you may have to select | ||
306 | 2 free major numbers for this driver. There are 3 steps to change | ||
307 | major numbers. | ||
308 | |||
309 | 1. Find free major numbers | ||
310 | In /proc/devices, you may find all the major numbers occupied | ||
311 | in the system. Please select 2 major numbers that are available. | ||
312 | e.g. 40, 45. | ||
313 | 2. Create special files | ||
314 | Run /moxa/mxser/driver/msmknod to create special files with | ||
315 | specified major numbers. | ||
316 | 3. Modify driver with new major number | ||
317 | Run vi to open /moxa/mxser/driver/mxser.c. Locate the line | ||
318 | contains "MXSERMAJOR". Change the content as below. | ||
319 | #define MXSERMAJOR 40 | ||
320 | #define MXSERCUMAJOR 45 | ||
321 | 4. Run # make install in /moxa/mxser/driver. | ||
322 | |||
323 | 3.6 Verify driver installation | ||
324 | You may refer to /var/log/messages to check the latest status | ||
325 | log reported by this driver whenever it's activated. | ||
326 | ----------------------------------------------------------------------------- | ||
327 | 4. Utilities | ||
328 | There are 3 utilities contained in this driver. They are msdiag, msmon and | ||
329 | msterm. These 3 utilities are released in form of source code. They should | ||
330 | be compiled into executable file and copied into /usr/bin. | ||
331 | |||
332 | msdiag - Diagnostic | ||
333 | -------------------- | ||
334 | This utility provides the function to detect what Moxa Smartio multiport | ||
335 | board exists in the system. | ||
336 | |||
337 | msmon - Port Monitoring | ||
338 | ----------------------- | ||
339 | This utility gives the user a quick view about all the MOXA ports' | ||
340 | activities. One can easily learn each port's total received/transmitted | ||
341 | (Rx/Tx) character count since the time when the monitoring is started. | ||
342 | Rx/Tx throughputs per second are also reported in interval basis (e.g. | ||
343 | the last 5 seconds) and in average basis (since the time the monitoring | ||
344 | is started). You can reset all ports' count by <HOME> key. <+> <-> | ||
345 | (plus/minus) keys to change the displaying time interval. Press <ENTER> | ||
346 | on the port, that cursor stay, to view the port's communication | ||
347 | parameters, signal status, and input/output queue. | ||
348 | |||
349 | msterm - Terminal Emulation | ||
350 | --------------------------- | ||
351 | This utility provides data sending and receiving ability of all tty ports, | ||
352 | especially for MOXA ports. It is quite useful for testing simple | ||
353 | application, for example, sending AT command to a modem connected to the | ||
354 | port or used as a terminal for login purpose. Note that this is only a | ||
355 | dumb terminal emulation without handling full screen operation. | ||
356 | ----------------------------------------------------------------------------- | ||
357 | 5. Setserial | ||
358 | |||
359 | Supported Setserial parameters are listed as below. | ||
360 | |||
361 | uart set UART type(16450-->disable FIFO, 16550A-->enable FIFO) | ||
362 | close_delay set the amount of time(in 1/100 of a second) that DTR | ||
363 | should be kept low while being closed. | ||
364 | closing_wait set the amount of time(in 1/100 of a second) that the | ||
365 | serial port should wait for data to be drained while | ||
366 | being closed, before the receiver is disable. | ||
367 | spd_hi Use 57.6kb when the application requests 38.4kb. | ||
368 | spd_vhi Use 115.2kb when the application requests 38.4kb. | ||
369 | spd_normal Use 38.4kb when the application requests 38.4kb. | ||
370 | |||
371 | ----------------------------------------------------------------------------- | ||
372 | 6. Troubleshooting | ||
373 | |||
374 | The boot time error messages and solutions are stated as clearly as | ||
375 | possible. If all the possible solutions fail, please contact our technical | ||
376 | support team to get more help. | ||
377 | |||
378 | Error msg: More than 4 Moxa Smartio family boards found. Fifth board and | ||
379 | after are ignored. | ||
380 | Solution: | ||
381 | To avoid this problem, please unplug fifth and after board, because Moxa | ||
382 | driver supports up to 4 boards. | ||
383 | |||
384 | Error msg: Request_irq fail, IRQ(?) may be conflict with another device. | ||
385 | Solution: | ||
386 | Other PCI or ISA devices occupy the assigned IRQ. If you are not sure | ||
387 | which device causes the situation,please check /proc/interrupts to find | ||
388 | free IRQ and simply change another free IRQ for Moxa board. | ||
389 | |||
390 | Error msg: Board #: C1xx Series(CAP=xxx) interrupt number invalid. | ||
391 | Solution: | ||
392 | Each port within the same multiport board shares the same IRQ. Please set | ||
393 | one IRQ (IRQ doesn't equal to zero) for one Moxa board. | ||
394 | |||
395 | Error msg: No interrupt vector be set for Moxa ISA board(CAP=xxx). | ||
396 | Solution: | ||
397 | Moxa ISA board needs an interrupt vector.Please refer to user's manual | ||
398 | "Hardware Installation" chapter to set interrupt vector. | ||
399 | |||
400 | Error msg: Couldn't install MOXA Smartio family driver! | ||
401 | Solution: | ||
402 | Load Moxa driver fail, the major number may conflict with other devices. | ||
403 | Please refer to previous section 3.5 to change a free major number for | ||
404 | Moxa driver. | ||
405 | |||
406 | Error msg: Couldn't install MOXA Smartio family callout driver! | ||
407 | Solution: | ||
408 | Load Moxa callout driver fail, the callout device major number may | ||
409 | conflict with other devices. Please refer to previous section 3.5 to | ||
410 | change a free callout device major number for Moxa driver. | ||
