3. Installation
3.1 Hardware installation
=========================
- There are two types of buses, ISA and PCI, for Smartio/Industio
- family multiport board.
-
-ISA board
----------
-
- You'll have to configure CAP address, I/O address, Interrupt Vector
- as well as IRQ before installing this driver. Please refer to hardware
- installation procedure in User's Manual before proceed any further.
- Please make sure the JP1 is open after the ISA board is set properly.
-
PCI/UPCI board
--------------
- You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict
- with other ISA devices. Please refer to hardware installation
- procedure in User's Manual in advance.
+ You may need to adjust IRQ usage in BIOS to avoid IRQ conflict with other
+ ISA devices. Please refer to hardware installation procedure in User's

PCI IRQ Sharing
---------------
together on one system and they can share the same IRQ.
-3.2 Driver files
-================
-
- The driver file may be obtained from ftp, CD-ROM or floppy disk. The
- first step, anyway, is to copy driver file "mxser.tgz" into specified
- directory. e.g. /moxa. The execute commands as below::
-
- # cd /
- # mkdir moxa
- # cd /moxa
- # tar xvf /dev/fd0
-
-or::
- # cd /
- # mkdir moxa
- # cd /moxa
- # cp /mnt/cdrom/<driver directory>/mxser.tgz .
- # tar xvfz mxser.tgz
-
-
-3.3 Device naming convention
+3.2 Device naming convention
============================
- You may find all the driver and utilities files in /moxa/mxser.
- Following installation procedure depends on the model you'd like to
- run the driver. If you prefer module driver, please refer to 3.4.
- If static driver is required, please refer to 3.5.
-
-Dialin and callout port
------------------------
-
- This driver remains traditional serial device properties. There are
- two special file name for each serial port. One is dial-in port
- which is named "ttyMxx". For callout port, the naming convention
- is "cumxx".
+ The device node is named "ttyMxx".
Device naming when more than 2 boards installed
-----------------------------------------------
Naming convention for each Smartio/Industio multiport board is
pre-defined as below.
- ============ =============== ==============
- Board Num. Dial-in Port Callout port
- 1st board ttyM0 - ttyM7 cum0 - cum7
- 2nd board ttyM8 - ttyM15 cum8 - cum15
- 3rd board ttyM16 - ttyM23 cum16 - cum23
- 4th board ttyM24 - ttym31 cum24 - cum31
- ============ =============== ==============
-
-.. note::
-
- Under Kernel 2.6 and upper, the cum Device is Obsolete. So use ttyM*
- device instead.
-
-Board sequence
---------------
-
- This driver will activate ISA boards according to the parameter set
- in the driver. After all specified ISA board activated, PCI board
- will be installed in the system automatically driven.
- Therefore the board number is sorted by the CAP address of ISA boards.
- For PCI boards, their sequence will be after ISA boards and C168H/PCI
- has higher priority than C104H/PCI boards.
-
-3.4 Module driver configuration
-===============================
-
- Module driver is easiest way to install. If you prefer static driver
- installation, please skip this paragraph.
-
-
- ------------- Prepare to use the MOXA driver --------------------
-
-3.4.1 Create tty device with correct major number
--------------------------------------------------
-
- Before using MOXA driver, your system must have the tty devices
- which are created with driver's major number. We offer one shell
- script "msmknod" to simplify the procedure.
- This step is only needed to be executed once. But you still
- need to do this procedure when:
-
- a. You change the driver's major number. Please refer the "3.7"
- section.
- b. Your total installed MOXA boards number is changed. Maybe you
- add/delete one MOXA board.
- c. You want to change the tty name. This needs to modify the
- shell script "msmknod"
-
- The procedure is::
-
- # cd /moxa/mxser/driver
- # ./msmknod
-
- This shell script will require the major number for dial-in
- device and callout device to create tty device. You also need
- to specify the total installed MOXA board number. Default major
- numbers for dial-in device and callout device are 30, 35. If
- you need to change to other number, please refer section "3.7"
- for more detailed procedure.
- Msmknod will delete any special files occupying the same device
- naming.
-
-3.4.2 Build the MOXA driver and utilities
------------------------------------------
-
- Before using the MOXA driver and utilities, you need compile the
- all the source code. This step is only need to be executed once.
- But you still re-compile the source code if you modify the source
- code. For example, if you change the driver's major number (see
- "3.7" section), then you need to do this step again.
-
- Find "Makefile" in /moxa/mxser, then run
-
- # make clean; make install
-
- ..note::
-
- For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
- # make clean; make installsp1
-
- For Red Hat Enterprise Linux AS4/ES4/WS4:
- # make clean; make installsp2
-
- The driver files "mxser.o" and utilities will be properly compiled
- and copied to system directories respectively.
-
-------------- Load MOXA driver--------------------
-
-3.4.3 Load the MOXA driver
---------------------------
-
- ::
-
- # modprobe mxser <argument>
-
- will activate the module driver. You may run "lsmod" to check
- if "mxser" is activated. If the MOXA board is ISA board, the
- <argument> is needed. Please refer to section "3.4.5" for more
- information.
-
-------------- Load MOXA driver on boot --------------------
-
-3.4.4 Load the mxser driver
----------------------------
-
-
- For the above description, you may manually execute
- "modprobe mxser" to activate this driver and run
- "rmmod mxser" to remove it.
-
- However, it's better to have a boot time configuration to
- eliminate manual operation. Boot time configuration can be
- achieved by rc file. We offer one "rc.mxser" file to simplify
- the procedure under "moxa/mxser/driver".
-
- But if you use ISA board, please modify the "modprobe ..." command
- to add the argument (see "3.4.5" section). After modifying the
- rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
- manually to make sure the modification is ok. If any error
- encountered, please try to modify again. If the modification is
- completed, follow the below step.
-
- Run following command for setting rc files::
-
- # cd /moxa/mxser/driver
- # cp ./rc.mxser /etc/rc.d
- # cd /etc/rc.d
-
- Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
- create it by vi, run "chmod 755 rc.serial" to change the permission.
-
- Add "/etc/rc.d/rc.mxser" in last line.
-
- Reboot and check if moxa.o activated by "lsmod" command.
-
-3.4.5. specify CAP address
---------------------------
-
- If you'd like to drive Smartio/Industio ISA boards in the system,
- you'll have to add parameter to specify CAP address of given
- board while activating "mxser.o". The format for parameters are
- as follows.::
-
- modprobe mxser ioaddr=0x???,0x???,0x???,0x???
- | | | |
- | | | +- 4th ISA board
- | | +------ 3rd ISA board
- | +------------ 2nd ISA board
- +-------------------1st ISA board
-
-3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
-================================================================
-
- Note:
- To use static driver, you must install the linux kernel
- source package.
-
-3.5.1 Backup the built-in driver in the kernel
-----------------------------------------------
-
- ::
-
- # cd /usr/src/linux/drivers/char
- # mv mxser.c mxser.c.old
-
- For Red Hat 7.x user, you need to create link:
- # cd /usr/src
- # ln -s linux-2.4 linux
-
-3.5.2 Create link
------------------
- ::
-
- # cd /usr/src/linux/drivers/char
- # ln -s /moxa/mxser/driver/mxser.c mxser.c
-
-3.5.3 Add CAP address list for ISA boards.
-------------------------------------------
-
- For PCI boards user, please skip this step.
-
- In module mode, the CAP address for ISA board is given by
- parameter. In static driver configuration, you'll have to
- assign it within driver's source code. If you will not
- install any ISA boards, you may skip to next portion.
- The instructions to modify driver source code are as
- below.
-
- a. run::
-
- # cd /moxa/mxser/driver
- # vi mxser.c
-
- b. Find the array mxserBoardCAP[] as below::
-
- static int mxserBoardCAP[] = {0x00, 0x00, 0x00, 0x00};
-
- c. Change the address within this array using vi. For
- example, to driver 2 ISA boards with CAP address
- 0x280 and 0x180 as 1st and 2nd board. Just to change
- the source code as follows::
-
- static int mxserBoardCAP[] = {0x280, 0x180, 0x00, 0x00};
-
-3.5.4 Setup kernel configuration
---------------------------------
-
- Configure the kernel::
-
- # cd /usr/src/linux
- # make menuconfig
-
- You will go into a menu-driven system. Please select [Character
- devices][Non-standard serial port support], enable the [Moxa
- SmartIO support] driver with "[*]" for built-in (not "[M]"), then
- select [Exit] to exit this program.
-
-3.5.5 Rebuild kernel
---------------------
-
- The following are for Linux kernel rebuilding, for your
- reference only.
-
- For appropriate details, please refer to the Linux document:
-
- a. Run the following commands::
-
- cd /usr/src/linux
- make clean # take a few minutes
- make dep # take a few minutes
- make bzImage # take probably 10-20 minutes
- make install # copy boot image to correct position
-
- f. Please make sure the boot kernel (vmlinuz) is in the
- correct position.
- g. If you use 'lilo' utility, you should check /etc/lilo.conf
- 'image' item specified the path which is the 'vmlinuz' path,
- or you will load wrong (or old) boot kernel image (vmlinuz).
- After checking /etc/lilo.conf, please run "lilo".
-
- Note that if the result of "make bzImage" is ERROR, then you have to
- go back to Linux configuration Setup. Type "make menuconfig" in
- directory /usr/src/linux.
-
-
-3.5.6 Make tty device and special file
---------------------------------------
-
- ::
- # cd /moxa/mxser/driver
- # ./msmknod
-
-3.5.7 Make utility
-------------------
-
- ::
-
- # cd /moxa/mxser/utility
- # make clean; make install
-
-3.5.8 Reboot
-------------
-
-
-
-3.6 Custom configuration
-========================
-
- Although this driver already provides you default configuration, you
- still can change the device name and major number. The instruction to
- change these parameters are shown as below.
-
-a. Change Device name
-
- If you'd like to use other device names instead of default naming
- convention, all you have to do is to modify the internal code
- within the shell script "msmknod". First, you have to open "msmknod"
- by vi. Locate each line contains "ttyM" and "cum" and change them
- to the device name you desired. "msmknod" creates the device names
- you need next time executed.
-
-b. Change Major number
-
- If major number 30 and 35 had been occupied, you may have to select
- 2 free major numbers for this driver. There are 3 steps to change
- major numbers.
-
-3.6.1 Find free major numbers
------------------------------
-
- In /proc/devices, you may find all the major numbers occupied
- in the system. Please select 2 major numbers that are available.
- e.g. 40, 45.
-
-3.6.2 Create special files
---------------------------
-
- Run /moxa/mxser/driver/msmknod to create special files with
- specified major numbers.
-
-3.6.3 Modify driver with new major number
------------------------------------------
-
- Run vi to open /moxa/mxser/driver/mxser.c. Locate the line
- contains "MXSERMAJOR". Change the content as below::
-
- #define MXSERMAJOR 40
- #define MXSERCUMAJOR 45
-
- 3.6.4 Run "make clean; make install" in /moxa/mxser/driver.
-
-3.7 Verify driver installation
-==============================
-
- You may refer to /var/log/messages to check the latest status
- log reported by this driver whenever it's activated.

6. Troubleshooting
^^^^^^^^^^^^^^^^^^
Solution:
To avoid this problem, please unplug fifth and after board, because Moxa
driver supports up to 4 boards.
-
- Error msg:
- Request_irq fail, IRQ(?) may be conflict with another device.
-
- Solution:
- Other PCI or ISA devices occupy the assigned IRQ. If you are not sure
- which device causes the situation, please check /proc/interrupts to find
- free IRQ and simply change another free IRQ for Moxa board.
-
- Error msg:
- Board #: C1xx Series(CAP=xxx) interrupt number invalid.
-
- Solution:
- Each port within the same multiport board shares the same IRQ. Please set
- one IRQ (IRQ doesn't equal to zero) for one Moxa board.
-
- Error msg:
- No interrupt vector be set for Moxa ISA board(CAP=xxx).
-
- Solution:
- Moxa ISA board needs an interrupt vector.Please refer to user's manual
- "Hardware Installation" chapter to set interrupt vector.
-
- Error msg:
- Couldn't install MOXA Smartio/Industio family driver!
-
- Solution:
- Load Moxa driver fail, the major number may conflict with other devices.
- Please refer to previous section 3.7 to change a free major number for
- Moxa driver.
-
- Error msg:
- Couldn't install MOXA Smartio/Industio family callout driver!
-
- Solution:
