1. Introduction

   The PC104 Communication Module Linux driver supports following multiport 
   boards.

    -CA-132, CA-132I series
     2 ports multiport board.
    -CA-104 series, 
     4 ports multiport board.

   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 [e-mail].

   In addition to device driver, useful utilities are also provided in this
   version. They are
    - mpdiag     Diagnostic program for displaying installed Moxa
      		 Communication Module.
    - mpmon      Monitor program to observe data count and line status signals.
    - mpterm     A simple terminal program which is useful in testing serial
	         ports.

   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://web.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

   3.1 Hardware installation

       There is only one type of bus, PC104 Bus, for PC104 Communication
       Module.

       You'll have to configure  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.


   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 "mxpcdrv.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>/mxpcdrv.tgz .
       # tar xvfz mxpcdrv.tgz


   3.3 Device naming convention
   
       You may find all the driver and utilities files in /moxa/mxpcdrv.
       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 & 3.6.

       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 "ttyNxx". For callout port, the naming convention
       is "cunxx".

       Device naming when more than 2 boards installed
       -----------------------------------------------
       Naming convention for each PC104 Communication Module is pre-defined 
       as below.

       Board Num.	 Dial-in Port	      Callout port
       1st board	ttyN0  - ttyN7	      cun0  - cun7
       2nd board	ttyN8  - ttyN15       cun8  - cun15
       3rd board	ttyN16 - ttyN23       cun16 - cun23
       4th board	ttyN24 - ttyN31       cun24 - cun31
       
       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
       Under Kernel 2.6 the cun Device is Obsolete. So use ttyN*
       device instead.
       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

       Board sequence
       --------------
       This driver will activate PC104 Bus boards according to the parameter set
       in the driver. Therefore the board number is sorted by the I/O address 
       of PC104 Bus 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 "mpmknod" 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 "mpmknod"

          The procedure is:
          
          # cd /moxa/mxpcdrv/driver
          # ./mpmknod

          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 34, 41. If
          you need to change to other number, please refer section "3.7"
          for more detailed procedure.
          Mpmknod 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/mxpcdrv, 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 "mxpcdrv.o" and utilities will be properly compiled
	  and copied to system directories respectively. 
          
       ------------- Load MOXA driver--------------------  
       3.4.3 Load the MOXA driver  

          # modprobe mxpcdrv <argument>

	  will activate the module driver. You may run "lsmod" to check
	  if "mxpcdrv.o" is activated. Because the MOXA board is PC104 Bus 
	  module, 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 mxpcdrv <argument>" to activate this driver and 
          run "rmmod mxpcdrv" 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.mxpcdrv" file to simplify 
          the procedure under "moxa/mxpcdrv/driver". 
          
          Because you use PC104 Bus board, please modify the "modprobe ..." 
	  command to add the argument (see "3.4.5" section). After modifying 
	  the rc.mxpcdrv, please try to execute 

	  "/moxa/mxpcdrv/driver/rc.mxpcdrv" 

          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/mxpcdrv/driver
	  # cp ./rc.mxpcdrv /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.
	  You also need to create link under /etc:
		# ln -s /etc/rc.d/rc.serial /etc/rc.serial
	  Add "/etc/rc.d/rc.mxpcdrv" in last line of rc.serial.

          Reboot and check if mxpcdrv.o activated by "lsmod" command.

       3.4.5. If you'd like to drive PC104 Communication Module in the system, 
          you'll have to add parameter to specify I/O address, Inteuuprt
	  Vector Address and IRQ of given board while activating mxpcdrv. 
	  The format for parameters are as follows.

	      modprobe mxpcdrv ioaddr=0x???,0x???,0x???,0x???
			       iovect=0x???,0x???,0x???,0x??? irq=?,?,?,?
