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.
