+
+ ------------- 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
