This driver and installation procedure have been developed upon Linux Kernel
Monitor program to observe data count and line status signals.
- msterm A simple terminal program which is useful in testing serial
ports.
- - io-irq.exe
- Configuration program to setup ISA boards. Please note that
- this program can only be executed under DOS.
All the drivers and utilities are published in form of source code under
GNU General Public License in this version. Please refer to GNU General
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
--------------
Under Kernel 2.6 and upper, the cum Device is Obsolete.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
===============================
::
- # modprobe mxser <argument>
+ # modprobe mxser
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.
+ if "mxser" is activated.
------------- Load MOXA driver on boot --------------------
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
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
================================================================
# 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};
-

select [Exit] to exit this program.
-3.5.5 Rebuild kernel
+3.5.4 Rebuild kernel
--------------------

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.
