1. Introduction

   The Smartio family Linux driver, Ver. 1.1, supports following multiport
   boards.

    -C104P/H/HS, C104H/PCI, C104HS/PCI, CI-104J 4 port multiport board.
    -C168P/H/HS, C168H/PCI 8 port multiport board.

   This driver has been modified a little and cleaned up from the Moxa
   contributed driver code and merged into Linux 2.2.14pre. In particular
   official major/minor numbers have been assigned which are different to
   those the original Moxa supplied driver used.

   This driver and installation procedure have been developed upon Linux Kernel
   2.2.5 and backward compatible to 2.0.3x. This driver supports Intel x86 and
   Alpha hardware platform. In order to maintain compatibility, this version
   has also been properly tested with RedHat, OpenLinux, TurboLinux 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
    - msdiag     Diagnostic program for detecting installed Moxa Smartio 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 ftp sites, you may always find latest driver at
   ftp://ftp.moxa.com  or ftp://ftp.moxa.com.tw.

   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 or Alpha machine
   - Kernel version: 2.0.3x or 2.2.x
   - gcc version 2.72 or later
   - Maximum 4 boards can be installed in combination

-----------------------------------------------------------------------------
3. Installation

   3.1 Hardware installation

       There are two types of buses, ISA and PCI, for Smartio 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 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.

       IRQ Sharing
       -----------
       Each port within the same multiport board shares the same IRQ. Up to
       4 Moxa Smartio Family multiport boards can be installed together on
       one system and they can share the same IRQ.

   3.2 Driver files and device naming convention

       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 /moxa
       # tar xvf /dev/fd0 
       or
       # cd /moxa
       # cp /mnt/cdrom/<driver directory>/mxser.tgz .
       # tar xvfz mxser.tgz

       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 3.3.
       If static driver is required, please refer to 3.4.

       Dialin and callout port
       -----------------------
       This driver remains traditional serial device properties. There're
       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 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

       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.

   3.3 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

	  The driver files "mxser.o" and utilities will be properly compiled
	  and copied to system directories respectively.Then run

	  # insmod mxser

	  to activate the modular driver. You may run "lsmod" to check
	  if "mxser.o" is activated.

       2. Create special files by executing "msmknod".
	  # cd /moxa/mxser/driver
	  # ./msmknod

	  Default major numbers for dial-in device and callout device are
	  174, 175. Msmknod will delete any special files occupying the same
	  device naming.

       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.

	  # 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.

	  if [ -f /etc/rc.d/rc.serial ]; then
	     sh /etc/rc.d/rc.serial
	  fi

       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.

	  insmod mxser ioaddr=0x???,0x???,0x???,0x???
				|      |     |	  |
				|      |     |	  +- 4th ISA board
				|      |     +------ 3rd ISA board
				|      +------------ 2nd ISA board
				+------------------- 1st ISA board

   3.4 Static driver configuration

       1. 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
	  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.
