Board sequence
--------------
This driver will activate ISA boards according to the parameter set
For PCI boards, their sequence will be after ISA boards and C168H/PCI
has higher priority than C104H/PCI boards.
- 3.3 Module driver configuration
+ 3.4 Module driver configuration
Module driver is easiest way to install. If you prefer static driver
installation, please skip this paragraph.
- 1. Find "Makefile" in /moxa/mxser, then run
- # make install
+
+ ------------- 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
+ !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
The driver files "mxser.o" and utilities will be properly compiled
- and copied to system directories respectively.Then run
+ and copied to system directories respectively.
- # insmod mxser
+ ------------- Load MOXA driver--------------------
+ 3.4.3 Load the MOXA driver
- to activate the modular driver. You may run "lsmod" to check
- if "mxser.o" is activated.
+ # modprobe mxser <argument>
- 2. Create special files by executing "msmknod".
- # cd /moxa/mxser/driver
- # ./msmknod
+ 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 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".
- Default major numbers for dial-in device and callout device are
- 174, 175. Msmknod will delete any special files occupying the same
- device naming.
+ 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.
- 3. Up to now, you may manually execute "insmod 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. Run following
- command for setting rc files.
+ Run following command for setting rc files.
# cd /moxa/mxser/driver
# cp ./rc.mxser /etc/rc.d
# cd /etc/rc.d
- You may have to modify part of the content in rc.mxser to specify
- parameters for ISA board. Please refer to rc.mxser for more detail.
- Find "rc.serial". If "rc.serial" doesn't exist, create it by vi.
- Add "rc.mxser" in last line. Next, open rc.local by vi
- and append following content.
+ 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,
- if [ -f /etc/rc.d/rc.serial ]; then
- sh /etc/rc.d/rc.serial
- fi
+ Reboot and check if moxa.o activated by "lsmod" command.
- 4. Reboot and check if mxser.o activated by "lsmod" command.
- 5. If you'd like to drive Smartio 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.
+ 3.4.5. 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

- 3.4 Static driver configuration
+ 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
- 1. Create link
+ 3.5.2 Create link
# cd /usr/src/linux/drivers/char
# ln -s /moxa/mxser/driver/mxser.c mxser.c
- 2. Add CAP address list for ISA boards
+ 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
static int mxserBoardCAP[]
= {0x280, 0x180, 0x00, 0x00};
- 3. Modify tty_io.c
- # cd /usr/src/linux/drivers/char/
- # vi tty_io.c
- Find pty_init(), insert "mxser_init()" as
+ 3.5.4 Setup kernel configuration
- pty_init();
- mxser_init();
+ Configure the kernel:
- 4. Modify tty.h
- # cd /usr/src/linux/include/linux
- # vi tty.h
- Find extern int tty_init(void), insert "mxser_init()" as
+ # cd /usr/src/linux
+ # make menuconfig
- extern int tty_init(void);
- extern int mxser_init(void);
-
- 5. Modify Makefile
- # cd /usr/src/linux/drivers/char
- # vi Makefile
- Find L_OBJS := tty_io.o ...... random.o, add
- "mxser.o" at last of this line as
- L_OBJS := tty_io.o ....... mxser.o
+ 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.
- 6. Rebuild kernel
- The following are for Linux kernel rebuilding,for your reference only.
+ 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.
- If 'lilo' utility is installed, please use 'make zlilo' to rebuild
- kernel. If 'lilo' is not installed, please follow the following steps.
-
a. cd /usr/src/linux
- b. make clean /* take a few minutes */
- c. make bzImage /* take probably 10-20 minutes */
- d. Backup original boot kernel. /* optional step */
- e. cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz
+ b. make clean /* take a few minutes */
+ c. make dep /* take a few minutes */
+ d. make bzImage /* take probably 10-20 minutes */
+ e. make install /* copy boot image to correct position */
f. Please make sure the boot kernel (vmlinuz) is in the
- correct position. 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).
- g. chmod 400 /vmlinuz
- h. lilo
- i. rdev -R /vmlinuz 1
- j. sync
-
- Note that if the result of "make zImage" is ERROR, then you have to
- go back to Linux configuration Setup. Type "make config" in directory
- /usr/src/linux or "setup".
-
- Since system include file, /usr/src/linux/include/linux/interrupt.h,
- is modified each time the MOXA driver is installed, kernel rebuilding
- is inevitable. And it takes about 10 to 20 minutes depends on the
- machine.
-
