-       1. Find "Makefile" in /moxa/mxser, then run
 
-          # make install
+
+       ------------- 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 installsp2

+       ------------- Load MOXA driver--------------------
+       3.4.3 Load the MOXA driver
 
-          to activate the modular driver. You may run "lsmod" to check
-          if "mxser.o" is activated.
+          # modprobe mxser <argument>
 
-       2. Create special files by executing "msmknod".
-          # cd /moxa/mxser/driver
-          # ./msmknod
+          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".
 
-          Default major numbers for dial-in device and callout device are
-          174, 175. Msmknod will delete any special files occupying the same
-          device naming.
+          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.
 
-       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.

-          Find "rc.serial". If "rc.serial" doesn't exist, create it by vi.
