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: - Load Moxa callout driver fail, the callout device major number may - conflict with other devices. Please refer to previous section 3.7 to - change a free callout device major number for Moxa driver. - - ------------------------------------------------------------------------------ - |
