 59    This driver and installation procedure have been developed upon Linux Kernel
 60    2.4.x and 2.6.x. This driver supports Intel x86 hardware platform. In order
 61    to maintain compatibility, this version has also been properly tested with
 62    RedHat, Mandrake, Fedora and S.u.S.E Linux. However, if compatibility problem
 63    occurs, please contact Moxa at support@moxa.com.tw.
 64 
 65    In addition to device driver, useful utilities are also provided in this
 66    version. They are
 67     - msdiag     Diagnostic program for displaying installed Moxa
 68                  Smartio/Industio boards.
 69     - msmon      Monitor program to observe data count and line status signals.
 70     - msterm     A simple terminal program which is useful in testing serial
 71                  ports.
 72     - io-irq.exe Configuration program to setup ISA boards. Please note that
 73                  this program can only be executed under DOS.

 99 
100    3.1 Hardware installation
101    3.2 Driver files
102    3.3 Device naming convention
103    3.4 Module driver configuration
104    3.5 Static driver configuration for Linux kernel 2.4.x, 2.6.x.
105    3.6 Custom configuration
106    3.7 Verify driver installation
107 
108 
109    3.1 Hardware installation
110 
111        There are two types of buses, ISA and PCI, for Smartio/Industio
112        family multiport board.
113 
114        ISA board
115        ---------
116        You'll have to configure CAP address, I/O address, Interrupt Vector
117        as well as IRQ before installing this driver. Please refer to hardware
118        installation procedure in User's Manual before proceed any further.
119        Please make sure the JP1 is open after the ISA board is set properly.
120 
121        PCI/UPCI board
122        --------------
123        You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict
124        with other ISA devices. Please refer to hardware installation
125        procedure in User's Manual in advance.
126 
127        PCI IRQ Sharing
128        -----------
129        Each port within the same multiport board shares the same IRQ. Up to
130        4 Moxa Smartio/Industio PCI Family multiport boards can be installed
131        together on one system and they can share the same IRQ.
132 
133 
134    3.2 Driver files
135 
136        The driver file may be obtained from ftp, CD-ROM or floppy disk. The
137        first step, anyway, is to copy driver file "mxser.tgz" into specified
138        directory. e.g. /moxa. The execute commands as below.
139 
140        # cd /
141        # mkdir moxa
142        # cd /moxa
143        # tar xvf /dev/fd0
144 
145        or
146 
147        # cd /
148        # mkdir moxa
149        # cd /moxa
150        # cp /mnt/cdrom/<driver directory>/mxser.tgz .
151        # tar xvfz mxser.tgz
152 
153 
154    3.3 Device naming convention
155 
156        You may find all the driver and utilities files in /moxa/mxser.
157        Following installation procedure depends on the model you'd like to
158        run the driver. If you prefer module driver, please refer to 3.4.
159        If static driver is required, please refer to 3.5.
160 
161        Dialin and callout port
162        -----------------------
163        This driver remains traditional serial device properties. There are
164        two special file name for each serial port. One is dial-in port
165        which is named "ttyMxx". For callout port, the naming convention
166        is "cumxx".
167 
168        Device naming when more than 2 boards installed
169        -----------------------------------------------
170        Naming convention for each Smartio/Industio multiport board is
171        pre-defined as below.
172 
173        Board Num.        Dial-in Port         Callout port
174        1st board        ttyM0  - ttyM7        cum0  - cum7
175        2nd board        ttyM8  - ttyM15       cum8  - cum15
176        3rd board        ttyM16 - ttyM23       cum16 - cum23
177        4th board        ttyM24 - ttym31       cum24 - cum31
178 
179 
180        !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
181        Under Kernel 2.6 the cum Device is Obsolete. So use ttyM*
182        device instead.
183        !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
184 
185        Board sequence
186        --------------
187        This driver will activate ISA boards according to the parameter set
188        in the driver. After all specified ISA board activated, PCI board
189        will be installed in the system automatically driven.
190        Therefore the board number is sorted by the CAP address of ISA boards.
191        For PCI boards, their sequence will be after ISA boards and C168H/PCI
192        has higher priority than C104H/PCI boards.
193 
194    3.4 Module driver configuration
195        Module driver is easiest way to install. If you prefer static driver
196        installation, please skip this paragraph.
197 
198 
199        ------------- Prepare to use the MOXA driver--------------------
200        3.4.1 Create tty device with correct major number
201           Before using MOXA driver, your system must have the tty devices
202           which are created with driver's major number. We offer one shell
203           script "msmknod" to simplify the procedure.
204           This step is only needed to be executed once. But you still
205           need to do this procedure when:
206           a. You change the driver's major number. Please refer the "3.7"
207              section.
208           b. Your total installed MOXA boards number is changed. Maybe you
209              add/delete one MOXA board.
210           c. You want to change the tty name. This needs to modify the
211              shell script "msmknod"
212 
213           The procedure is:
214           # cd /moxa/mxser/driver
215           # ./msmknod
216 
217           This shell script will require the major number for dial-in
218           device and callout device to create tty device. You also need
219           to specify the total installed MOXA board number. Default major
220           numbers for dial-in device and callout device are 30, 35. If
221           you need to change to other number, please refer section "3.7"
222           for more detailed procedure.
223           Msmknod will delete any special files occupying the same device
224           naming.
225 
226        3.4.2 Build the MOXA driver and utilities
227           Before using the MOXA driver and utilities, you need compile the
228           all the source code. This step is only need to be executed once.
229           But you still re-compile the source code if you modify the source
230           code. For example, if you change the driver's major number (see
231           "3.7" section), then you need to do this step again.
232 
233           Find "Makefile" in /moxa/mxser, then run
234 
235           # make clean; make install
236 
237           !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
238           For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
239           # make clean; make installsp1
240 
241           For Red Hat Enterprise Linux AS4/ES4/WS4:
242           # make clean; make installsp2
243           !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
244 
245           The driver files "mxser.o" and utilities will be properly compiled
246           and copied to system directories respectively.
247 
248        ------------- Load MOXA driver--------------------
249        3.4.3 Load the MOXA driver
250 
251           # modprobe mxser <argument>
252 
253           will activate the module driver. You may run "lsmod" to check
254           if "mxser" is activated. If the MOXA board is ISA board, the
255           <argument> is needed. Please refer to section "3.4.5" for more
256           information.
257 
258 
259        ------------- Load MOXA driver on boot --------------------
260        3.4.4 For the above description, you may manually execute
261           "modprobe mxser" to activate this driver and run
262           "rmmod mxser" to remove it.
263           However, it's better to have a boot time configuration to
264           eliminate manual operation. Boot time configuration can be
265           achieved by rc file. We offer one "rc.mxser" file to simplify
266           the procedure under "moxa/mxser/driver".
267 
268           But if you use ISA board, please modify the "modprobe ..." command
269           to add the argument (see "3.4.5" section). After modifying the
270           rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
271           manually to make sure the modification is ok. If any error
272           encountered, please try to modify again. If the modification is
273           completed, follow the below step.
274 
275           Run following command for setting rc files.
276 
277           # cd /moxa/mxser/driver
278           # cp ./rc.mxser /etc/rc.d
279           # cd /etc/rc.d
280 
281           Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
282           create it by vi, run "chmod 755 rc.serial" to change the permission.
283           Add "/etc/rc.d/rc.mxser" in last line,
284 
285           Reboot and check if moxa.o activated by "lsmod" command.
286 
287        3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system,
288           you'll have to add parameter to specify CAP address of given
289           board while activating "mxser.o". The format for parameters are
290           as follows.
291 
292           modprobe mxser ioaddr=0x???,0x???,0x???,0x???
293                                 |      |     |    |
294                                 |      |     |    +- 4th ISA board
295                                 |      |     +------ 3rd ISA board
296                                 |      +------------ 2nd ISA board
297                                 +------------------- 1st ISA board
298 
299    3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
300 
301        Note: To use static driver, you must install the linux kernel
302              source package.
303 
304        3.5.1 Backup the built-in driver in the kernel.
305           # cd /usr/src/linux/drivers/char
306           # mv mxser.c mxser.c.old
307 
308           For Red Hat 7.x user, you need to create link:
309           # cd /usr/src
310           # ln -s linux-2.4 linux
311 
312        3.5.2 Create link
313           # cd /usr/src/linux/drivers/char
314           # ln -s /moxa/mxser/driver/mxser.c mxser.c
315 
316        3.5.3 Add CAP address list for ISA boards. For PCI boards user,
317           please skip this step.
318 
319           In module mode, the CAP address for ISA board is given by
320           parameter. In static driver configuration, you'll have to
321           assign it within driver's source code. If you will not
322           install any ISA boards, you may skip to next portion.
323           The instructions to modify driver source code are as
324           below.
325           a. # cd /moxa/mxser/driver
326              # vi mxser.c
327           b. Find the array mxserBoardCAP[] as below.
328 
329              static int mxserBoardCAP[]
330              = {0x00, 0x00, 0x00, 0x00};
331 
332           c. Change the address within this array using vi. For
333              example, to driver 2 ISA boards with CAP address
334              0x280 and 0x180 as 1st and 2nd board. Just to change
335              the source code as follows.
336 
337              static int mxserBoardCAP[]
338              = {0x280, 0x180, 0x00, 0x00};
339 
340        3.5.4 Setup kernel configuration
341 
342           Configure the kernel:
343 
344             # cd /usr/src/linux
345             # make menuconfig
346 
347           You will go into a menu-driven system. Please select [Character
348           devices][Non-standard serial port support], enable the [Moxa
349           SmartIO support] driver with "[*]" for built-in (not "[M]"), then
350           select [Exit] to exit this program.
351 
352        3.5.5 Rebuild kernel
353           The following are for Linux kernel rebuilding, for your
354           reference only.
355           For appropriate details, please refer to the Linux document.
356 
357            a. cd /usr/src/linux
358            b. make clean             /* take a few minutes */
359            c. make dep               /* take a few minutes */
360            d. make bzImage           /* take probably 10-20 minutes */
361            e. make install           /* copy boot image to correct position */
362            f. Please make sure the boot kernel (vmlinuz) is in the
363               correct position.
364            g. If you use 'lilo' utility, you should check /etc/lilo.conf
365               'image' item specified the path which is the 'vmlinuz' path,
366               or you will load wrong (or old) boot kernel image (vmlinuz).
367               After checking /etc/lilo.conf, please run "lilo".
368 
369           Note that if the result of "make bzImage" is ERROR, then you have to
370           go back to Linux configuration Setup. Type "make menuconfig" in
371           directory /usr/src/linux.

386    3.6 Custom configuration
387        Although this driver already provides you default configuration, you
388        still can change the device name and major number. The instruction to
389        change these parameters are shown as below.
390 
391        Change Device name
392        ------------------
393        If you'd like to use other device names instead of default naming
394        convention, all you have to do is to modify the internal code
395        within the shell script "msmknod". First, you have to open "msmknod"
396        by vi. Locate each line contains "ttyM" and "cum" and change them
397        to the device name you desired. "msmknod" creates the device names
398        you need next time executed.
399 
400        Change Major number
401        -------------------
402        If major number 30 and 35 had been occupied, you may have to select
403        2 free major numbers for this driver. There are 3 steps to change
404        major numbers.
405 
406        3.6.1 Find free major numbers
407           In /proc/devices, you may find all the major numbers occupied
408           in the system. Please select 2 major numbers that are available.
409           e.g. 40, 45.
410        3.6.2 Create special files
411           Run /moxa/mxser/driver/msmknod to create special files with
412           specified major numbers.
413        3.6.3 Modify driver with new major number
414           Run vi to open /moxa/mxser/driver/mxser.c. Locate the line
415           contains "MXSERMAJOR". Change the content as below.
416           #define         MXSERMAJOR              40
417           #define         MXSERCUMAJOR            45
418        3.6.4 Run "make clean; make install" in /moxa/mxser/driver.
419 
420    3.7 Verify driver installation
421        You may refer to /var/log/messages to check the latest status
422        log reported by this driver whenever it's activated.
423 
424 -----------------------------------------------------------------------------
425 4. Utilities
426    There are 3 utilities contained in this driver. They are msdiag, msmon and
427    msterm. These 3 utilities are released in form of source code. They should
428    be compiled into executable file and copied into /usr/bin.
429 
430    Before using these utilities, please load driver (refer 3.4 & 3.5) and
431    make sure you had run the "msmknod" utility.
432 
433    msdiag - Diagnostic
434    --------------------
435    This utility provides the function to display what Moxa Smartio/Industio
436    board found by driver in the system.
437 
438    msmon - Port Monitoring
439    -----------------------
440    This utility gives the user a quick view about all the MOXA ports'
441    activities. One can easily learn each port's total received/transmitted
442    (Rx/Tx) character count since the time when the monitoring is started.
443    Rx/Tx throughputs per second are also reported in interval basis (e.g.
444    the last 5 seconds) and in average basis (since the time the monitoring
445    is started). You can reset all ports' count by <HOME> key. <+> <->
446    (plus/minus) keys to change the displaying time interval. Press <ENTER>
447    on the port, that cursor stay, to view the port's communication
448    parameters, signal status, and input/output queue.
449 
450    msterm - Terminal Emulation
451    ---------------------------
452    This utility provides data sending and receiving ability of all tty ports,
453    especially for MOXA ports. It is quite useful for testing simple
454    application, for example, sending AT command to a modem connected to the
455    port or used as a terminal for login purpose. Note that this is only a
456    dumb terminal emulation without handling full screen operation.
457 
458 -----------------------------------------------------------------------------
459 5. Setserial
460 
461    Supported Setserial parameters are listed as below.
