  983. Installation
  99
 100   3.1 Hardware installation
 101   3.2 Driver files
 102   3.3 Device naming convention
 103   3.4 Module driver configuration
 104   3.5 Static driver configuration for Linux kernel 2.4.x, 2.6.x.
 105   3.6 Custom configuration
 106   3.7 Verify driver installation
 107
 108
 109   3.1 Hardware installation
 110
 111       There are two types of buses, ISA and PCI, for Smartio/Industio
 112       family multiport board.
 113
 114       ISA board
 115       ---------
 116       You'll have to configure CAP address, I/O address, Interrupt Vector
 117       as well as IRQ before installing this driver. Please refer to hardware
 118       installation procedure in User's Manual before proceed any further.
 119       Please make sure the JP1 is open after the ISA board is set properly.
 120
 121       PCI/UPCI board
 122       --------------
 123       You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict
 124       with other ISA devices. Please refer to hardware installation
 125       procedure in User's Manual in advance.
 126
 127       PCI IRQ Sharing
 128       -----------
 129       Each port within the same multiport board shares the same IRQ. Up to
 130       4 Moxa Smartio/Industio PCI Family multiport boards can be installed
 131       together on one system and they can share the same IRQ.
 132
 133
 134   3.2 Driver files
 135
 136       The driver file may be obtained from ftp, CD-ROM or floppy disk. The
 137       first step, anyway, is to copy driver file "mxser.tgz" into specified
 138       directory. e.g. /moxa. The execute commands as below.
 139
 140       # cd /
 141       # mkdir moxa
 142       # cd /moxa
 143       # tar xvf /dev/fd0
 144
 145       or
 146
 147       # cd /
 148       # mkdir moxa
 149       # cd /moxa
 150       # cp /mnt/cdrom/<driver directory>/mxser.tgz .
 151       # tar xvfz mxser.tgz
 152
 153
 154   3.3 Device naming convention
 155
 156       You may find all the driver and utilities files in /moxa/mxser.
 157       Following installation procedure depends on the model you'd like to
 158       run the driver. If you prefer module driver, please refer to 3.4.
 159       If static driver is required, please refer to 3.5.
 160
 161       Dialin and callout port
 162       -----------------------
 163       This driver remains traditional serial device properties. There are
 164       two special file name for each serial port. One is dial-in port
 165       which is named "ttyMxx". For callout port, the naming convention
 166       is "cumxx".
 167
 168       Device naming when more than 2 boards installed
 169       -----------------------------------------------
 170       Naming convention for each Smartio/Industio multiport board is
 171       pre-defined as below.
 172
 173       Board Num.        Dial-in Port         Callout port
 174       1st board        ttyM0  - ttyM7        cum0  - cum7
 175       2nd board        ttyM8  - ttyM15       cum8  - cum15
 176       3rd board        ttyM16 - ttyM23       cum16 - cum23
 177       4th board        ttyM24 - ttym31       cum24 - cum31
 178
 179
 180       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 181       Under Kernel 2.6 the cum Device is Obsolete. So use ttyM*
 182       device instead.
 183       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 184
 185       Board sequence
 186       --------------
 187       This driver will activate ISA boards according to the parameter set
 188       in the driver. After all specified ISA board activated, PCI board
 189       will be installed in the system automatically driven.
 190       Therefore the board number is sorted by the CAP address of ISA boards.
 191       For PCI boards, their sequence will be after ISA boards and C168H/PCI
 192       has higher priority than C104H/PCI boards.
 193
 194   3.4 Module driver configuration
 195       Module driver is easiest way to install. If you prefer static driver
 196       installation, please skip this paragraph.
 197
 198
 199       ------------- Prepare to use the MOXA driver--------------------
 200       3.4.1 Create tty device with correct major number
 201          Before using MOXA driver, your system must have the tty devices
 202          which are created with driver's major number. We offer one shell
 203          script "msmknod" to simplify the procedure.
 204          This step is only needed to be executed once. But you still
 205          need to do this procedure when:
 206          a. You change the driver's major number. Please refer the "3.7"
 207             section.
 208          b. Your total installed MOXA boards number is changed. Maybe you
 209             add/delete one MOXA board.
 210          c. You want to change the tty name. This needs to modify the
 211             shell script "msmknod"
 212
 213          The procedure is:
 214          # cd /moxa/mxser/driver
 215          # ./msmknod
 216
 217          This shell script will require the major number for dial-in
 218          device and callout device to create tty device. You also need
 219          to specify the total installed MOXA board number. Default major
 220          numbers for dial-in device and callout device are 30, 35. If
 221          you need to change to other number, please refer section "3.7"
 222          for more detailed procedure.
 223          Msmknod will delete any special files occupying the same device
 224          naming.
 225
 226       3.4.2 Build the MOXA driver and utilities
 227          Before using the MOXA driver and utilities, you need compile the
 228          all the source code. This step is only need to be executed once.
 229          But you still re-compile the source code if you modify the source
 230          code. For example, if you change the driver's major number (see
 231          "3.7" section), then you need to do this step again.
 232
 233          Find "Makefile" in /moxa/mxser, then run
 234
 235          # make clean; make install
 236
 237          !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
 238          For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
 239          # make clean; make installsp1
 240
 241          For Red Hat Enterprise Linux AS4/ES4/WS4:
 242          # make clean; make installsp2
 243          !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
 244
 245          The driver files "mxser.o" and utilities will be properly compiled
 246          and copied to system directories respectively.
 247
 248       ------------- Load MOXA driver--------------------
 249       3.4.3 Load the MOXA driver
 250
 251          # modprobe mxser <argument>
 252
 253          will activate the module driver. You may run "lsmod" to check
 254          if "mxser" is activated. If the MOXA board is ISA board, the
 255          <argument> is needed. Please refer to section "3.4.5" for more
 256          information.
 257
 258
 259       ------------- Load MOXA driver on boot --------------------
 260       3.4.4 For the above description, you may manually execute
 261          "modprobe mxser" to activate this driver and run
 262          "rmmod mxser" to remove it.
 263          However, it's better to have a boot time configuration to
 264          eliminate manual operation. Boot time configuration can be
 265          achieved by rc file. We offer one "rc.mxser" file to simplify
 266          the procedure under "moxa/mxser/driver".
 267
 268          But if you use ISA board, please modify the "modprobe ..." command
 269          to add the argument (see "3.4.5" section). After modifying the
 270          rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
 271          manually to make sure the modification is ok. If any error
 272          encountered, please try to modify again. If the modification is
 273          completed, follow the below step.
 274
 275          Run following command for setting rc files.
 276
 277          # cd /moxa/mxser/driver
 278          # cp ./rc.mxser /etc/rc.d
 279          # cd /etc/rc.d
 280
 281          Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
 282          create it by vi, run "chmod 755 rc.serial" to change the permission.
 283          Add "/etc/rc.d/rc.mxser" in last line,
 284
 285          Reboot and check if moxa.o activated by "lsmod" command.
 286
 287       3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system,
 288          you'll have to add parameter to specify CAP address of given
 289          board while activating "mxser.o". The format for parameters are
 290          as follows.
 291
 292          modprobe mxser ioaddr=0x???,0x???,0x???,0x???
 293                                |      |     |    |
 294                                |      |     |    +- 4th ISA board
 295                                |      |     +------ 3rd ISA board
 296                                |      +------------ 2nd ISA board
 297                                +------------------- 1st ISA board
 298
 299   3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
 300
 301       Note: To use static driver, you must install the linux kernel
 302             source package.
 303
 304       3.5.1 Backup the built-in driver in the kernel.
 305          # cd /usr/src/linux/drivers/char
 306          # mv mxser.c mxser.c.old
 307
 308          For Red Hat 7.x user, you need to create link:
 309          # cd /usr/src
 310          # ln -s linux-2.4 linux
 311
 312       3.5.2 Create link
 313          # cd /usr/src/linux/drivers/char
 314          # ln -s /moxa/mxser/driver/mxser.c mxser.c
 315
 316       3.5.3 Add CAP address list for ISA boards. For PCI boards user,
 317          please skip this step.
 318
 319          In module mode, the CAP address for ISA board is given by
 320          parameter. In static driver configuration, you'll have to
 321          assign it within driver's source code. If you will not
 322          install any ISA boards, you may skip to next portion.
 323          The instructions to modify driver source code are as
 324          below.
 325          a. # cd /moxa/mxser/driver
 326             # vi mxser.c
 327          b. Find the array mxserBoardCAP[] as below.
 328
 329             static int mxserBoardCAP[]
 330             = {0x00, 0x00, 0x00, 0x00};
 331
 332          c. Change the address within this array using vi. For
 333             example, to driver 2 ISA boards with CAP address
 334             0x280 and 0x180 as 1st and 2nd board. Just to change
 335             the source code as follows.
 336
 337             static int mxserBoardCAP[]
 338             = {0x280, 0x180, 0x00, 0x00};
 339
 340       3.5.4 Setup kernel configuration
 341
 342          Configure the kernel:
 343
 344            # cd /usr/src/linux
 345            # make menuconfig
 346
 347          You will go into a menu-driven system. Please select [Character
 348          devices][Non-standard serial port support], enable the [Moxa
 349          SmartIO support] driver with "[*]" for built-in (not "[M]"), then
 350          select [Exit] to exit this program.
 351
 352       3.5.5 Rebuild kernel
 353          The following are for Linux kernel rebuilding, for your
 354          reference only.
 355          For appropriate details, please refer to the Linux document.
 356
 357           a. cd /usr/src/linux
 358           b. make clean             /* take a few minutes */
 359           c. make dep               /* take a few minutes */
 360           d. make bzImage           /* take probably 10-20 minutes */
 361           e. make install           /* copy boot image to correct position */
 362           f. Please make sure the boot kernel (vmlinuz) is in the
 363              correct position.
 364           g. If you use 'lilo' utility, you should check /etc/lilo.conf
 365              'image' item specified the path which is the 'vmlinuz' path,
 366              or you will load wrong (or old) boot kernel image (vmlinuz).
 367              After checking /etc/lilo.conf, please run "lilo".
 368
 369          Note that if the result of "make bzImage" is ERROR, then you have to
 370          go back to Linux configuration Setup. Type "make menuconfig" in
 371          directory /usr/src/linux.
 372
 373
 374       3.5.6 Make tty device and special file
 375          # cd /moxa/mxser/driver
 376          # ./msmknod
 377
 378       3.5.7 Make utility
 379          # cd /moxa/mxser/utility
 380          # make clean; make install
 381
 382       3.5.8 Reboot
 383
 384
 385
 386   3.6 Custom configuration
 387       Although this driver already provides you default configuration, you
 388       still can change the device name and major number. The instruction to
 389       change these parameters are shown as below.
 390
 391       Change Device name
 392       ------------------
 393       If you'd like to use other device names instead of default naming
 394       convention, all you have to do is to modify the internal code
 395       within the shell script "msmknod". First, you have to open "msmknod"
 396       by vi. Locate each line contains "ttyM" and "cum" and change them
 397       to the device name you desired. "msmknod" creates the device names
 398       you need next time executed.
 399
 400       Change Major number
 401       -------------------
 402       If major number 30 and 35 had been occupied, you may have to select
 403       2 free major numbers for this driver. There are 3 steps to change
 404       major numbers.
 405
 406       3.6.1 Find free major numbers
 407          In /proc/devices, you may find all the major numbers occupied
 408          in the system. Please select 2 major numbers that are available.
 409          e.g. 40, 45.
 410       3.6.2 Create special files
 411          Run /moxa/mxser/driver/msmknod to create special files with
 412          specified major numbers.
 413       3.6.3 Modify driver with new major number
 414          Run vi to open /moxa/mxser/driver/mxser.c. Locate the line
 415          contains "MXSERMAJOR". Change the content as below.
 416          #define         MXSERMAJOR              40
 417          #define         MXSERCUMAJOR            45
 418       3.6.4 Run "make clean; make install" in /moxa/mxser/driver.
 419
 420   3.7 Verify driver installation
 421       You may refer to /var/log/messages to check the latest status
 422       log reported by this driver whenever it's activated.
 423
 424-----------------------------------------------------------------------------
 4254. Utilities
 426   There are 3 utilities contained in this driver. They are msdiag, msmon and
 427   msterm. These 3 utilities are released in form of source code. They should
 428   be compiled into executable file and copied into /usr/bin.
 429
 430   Before using these utilities, please load driver (refer 3.4 & 3.5) and
 431   make sure you had run the "msmknod" utility.
 432
 433   msdiag - Diagnostic
 434   --------------------
 435   This utility provides the function to display what Moxa Smartio/Industio
 436   board found by driver in the system.
 437
 438   msmon - Port Monitoring
 439   -----------------------
 440   This utility gives the user a quick view about all the MOXA ports'
 441   activities. One can easily learn each port's total received/transmitted
 442   (Rx/Tx) character count since the time when the monitoring is started.
 443   Rx/Tx throughputs per second are also reported in interval basis (e.g.
 444   the last 5 seconds) and in average basis (since the time the monitoring
 445   is started). You can reset all ports' count by <HOME> key. <+> <->
 446   (plus/minus) keys to change the displaying time interval. Press <ENTER>
 447   on the port, that cursor stay, to view the port's communication
 448   parameters, signal status, and input/output queue.
 449
 450   msterm - Terminal Emulation
 451   ---------------------------
 452   This utility provides data sending and receiving ability of all tty ports,
 453   especially for MOXA ports. It is quite useful for testing simple
 454   application, for example, sending AT command to a modem connected to the
 455   port or used as a terminal for login purpose. Note that this is only a
 456   dumb terminal emulation without handling full screen operation.
 457
 458-----------------------------------------------------------------------------
 4595. Setserial
 460
 461   Supported Setserial parameters are listed as below.
 462
 463   uart           set UART type(16450-->disable FIFO, 16550A-->enable FIFO)
 464   close_delay    set the amount of time(in 1/100 of a second) that DTR
 465                  should be kept low while being closed.
 466   closing_wait   set the amount of time(in 1/100 of a second) that the
 467                  serial port should wait for data to be drained while
 468                  being closed, before the receiver is disable.
