NPort 5600-8-DT/DTL Series TTY Drivers for Linux and UNIX
Linux Real TTY Drivers
Real TTY driver are provided that will map Linux host TTY ports to NPort device ports. Once the mapping has
been set up, Linux users and applications can connect to a device port as if it were a local TTY port. These
drivers have been designed and tested for the majority of Linux distributions, including Linux kernel version
2.4.x and 2.6.x. Please check Moxa’s website (
http://www.moxa.com) for the latest Linux kernel support. For
more detail, please refer to README.TXT.
Basic Steps
Follow these instructions to map a TTY port to a device port:
Install the NPort device server and set the target device port to Real COM mode.
Install the Real TTY driver files on the Linux host.
Map the host’s TTY port to the target device port on the NPort.
Installing Linux Real TTY Driver Files
Before proceeding with the software installation, make sure you have completed the NPort device server has
been installed and configured correctly. Note that the default IP address for the NPort is 192.168.127.254.
ATTENTION
The target device port must be operating in Real COM mode i
n order to map TTY ports.
1. Obtain the driver file from the Document and Software CD, or from the Moxa website at
http://www.moxa.com.
2. Log in to the console as a super user (root).
Execute cd / to go to the root directory.
Copy the driver file npreal2xx.tgz to the / directory.
Execute tar xvfz npreal2xx.tgz to extract all files into the system.
Execute /tmp/moxa/mxinst.
For RedHat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/moxa/mxinst SP1
The shell script will install the driver files automatically.
After installing the driver, you will be able to see several files in the /usr/lib/npreal2/driver folder:
> mxaddsvr (Add Server, mapping tty port)
> mxdelsvr (Delete Server, un-mapping tty port)
> mxloadsvr (Reload Server)
> mxmknod (Create device node/tty port)
> mxrmnod (Remove device node/tty port)
> mxuninst (Remove tty port and driver files)
At this point, you may map the TTY port to the NPort serial port.
Mapping TTY Ports
Make sure that you set the operation mode of the desired NPort serial port to Real COM mode. After logging in
as a super user, enter the directory /usr/lib/npreal2/driver and then execute mxaddsvr to map the target
NPort serial port to the host TTY ports. The syntax of mxaddsvr is as follows:
mxaddsvr [NPort IP Address] [Total Ports] ([Data port] [Cmd port])
