+
+ This driver and installation procedure have been developed upon Linux Kernel
+ 2.4.x and 2.6.x. This driver supports Intel x86 hardware platform. In order
+ to maintain compatibility, this version has also been properly tested with
+ RedHat, Mandrake, Fedora and S.u.S.E Linux. However, if compatibility problem
+ occurs, please contact Moxa at support@moxa.com.tw.
+
+ In addition to device driver, useful utilities are also provided in this
+ version. They are
+ - msdiag Diagnostic program for displaying installed Moxa
+ Smartio/Industio boards.
+ - msmon 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
+ Public License announcement in each source code file for more detail.
+
+ In Moxa's Web sites, you may always find latest driver at http://www.moxa.com/.
+
+ This version of driver can be installed as Loadable Module (Module driver)
+ or built-in into kernel (Static driver). You may refer to following
+ installation procedure for suitable one. Before you install the driver,
+ please refer to hardware installation procedure in the User's Manual.
+
+ We assume the user should be familiar with following documents.
+ - Serial-HOWTO
+ - Kernel-HOWTO
+
+-----------------------------------------------------------------------------
+2. System Requirement
+ - Hardware platform: Intel x86 machine
+ - Kernel version: 2.4.x or 2.6.x
+ - gcc version 2.72 or later
+ - Maximum 4 boards can be installed in combination
+
+-----------------------------------------------------------------------------
+3. Installation
+
+ 3.1 Hardware installation
+ 3.2 Driver files
+ 3.3 Device naming convention
+ 3.4 Module driver configuration
+ 3.5 Static driver configuration for Linux kernel 2.4.x, 2.6.x.
+ 3.6 Custom configuration
+ 3.7 Verify driver 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.
+
+ PCI IRQ Sharing
+ -----------
+ Each port within the same multiport board shares the same IRQ. Up to
+ 4 Moxa Smartio/Industio PCI Family multiport boards can be installed
+ 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
+
+ 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".
+
+ 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 the cum Device is Obsolete. So use ttyM*
+ device instead.
+ !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+ 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
+ !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
+
+ 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 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. 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. # 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. cd /usr/src/linux
+ 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.
+ 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.
+
+ 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.
+
+ 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.
+
+-----------------------------------------------------------------------------
+4. Utilities
+ There are 3 utilities contained in this driver. They are msdiag, msmon and
+ msterm. These 3 utilities are released in form of source code. They should
+ be compiled into executable file and copied into /usr/bin.
+
+ Before using these utilities, please load driver (refer 3.4 & 3.5) and
+ make sure you had run the "msmknod" utility.
+
+ msdiag - Diagnostic
+ --------------------
+ This utility provides the function to display what Moxa Smartio/Industio
+ board found by driver in the system.
+
+ msmon - Port Monitoring
+ -----------------------
+ This utility gives the user a quick view about all the MOXA ports'
+ activities. One can easily learn each port's total received/transmitted
+ (Rx/Tx) character count since the time when the monitoring is started.
+ Rx/Tx throughputs per second are also reported in interval basis (e.g.
+ the last 5 seconds) and in average basis (since the time the monitoring
+ is started). You can reset all ports' count by <HOME> key. <+> <->
+ (plus/minus) keys to change the displaying time interval. Press <ENTER>
+ on the port, that cursor stay, to view the port's communication
+ parameters, signal status, and input/output queue.
+
+ msterm - Terminal Emulation
+ ---------------------------
+ This utility provides data sending and receiving ability of all tty ports,
+ especially for MOXA ports. It is quite useful for testing simple
+ application, for example, sending AT command to a modem connected to the
+ port or used as a terminal for login purpose. Note that this is only a
+ dumb terminal emulation without handling full screen operation.
+
+-----------------------------------------------------------------------------
+5. Setserial
+
+ Supported Setserial parameters are listed as below.
+
+ uart set UART type(16450-->disable FIFO, 16550A-->enable FIFO)
+ close_delay set the amount of time(in 1/100 of a second) that DTR
+ should be kept low while being closed.
+ closing_wait set the amount of time(in 1/100 of a second) that the
+ serial port should wait for data to be drained while
+ being closed, before the receiver is disable.
+ spd_hi Use 57.6kb when the application requests 38.4kb.
+ spd_vhi Use 115.2kb when the application requests 38.4kb.
+ spd_shi Use 230.4kb when the application requests 38.4kb.
+ spd_warp Use 460.8kb when the application requests 38.4kb.
+ spd_normal Use 38.4kb when the application requests 38.4kb.
+ spd_cust Use the custom divisor to set the speed when the
+ application requests 38.4kb.
+ divisor This option set the custom division.
+ baud_base This option set the base baud rate.
+
+-----------------------------------------------------------------------------
+6. Troubleshooting
+
+ The boot time error messages and solutions are stated as clearly as
+ possible. If all the possible solutions fail, please contact our technical
+ support team to get more help.
+
+
+ Error msg: More than 4 Moxa Smartio/Industio family boards found. Fifth board
+ and after are ignored.
+ 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:
