Mapping TTY ports automatically
To map TTY ports automatically, you may execute
mxaddsvr
with just the IP address and number of ports,
as in the following example:
# cd /usr/lib/npreal2/driver
# ./mxaddsvr 192.168.3.4 16
In this example, 16 TTY ports will be added, all with IP 192.168.3.4, with data ports from 950 to 965 and
command ports from 966 to 981.
Mapping TTY ports manually
To map TTY ports manually, you may execute
mxaddsvr
and manually specify the data and command
ports, as in the following example:
# cd /usr/lib/npreal2/driver
# ./mxaddsvr 192.168.3.4 16 4001 966
In this example, 16 TTY ports will be added, all with IP 192.168.3.4, with data ports from 4001 to 4016 and
command ports from 966 to 981.
Removing Mapped TTY Ports
After logging in as root, enter the directory
/usr/lib/npreal2/driver
and then execute
mxdelsvr
to
delete a server. The syntax of mxdelsvr is:
mxdelsvr
[
IP Address
]
Example:
# cd /usr/lib/npreal2/driver
# ./mxdelsvr 192.168.3.4
The following actions are performed when executing
mxdelsvr
:
1.
Change npreal2d.cf.
2.
Remove the relevant TTY ports in directory /dev.
3.
Restart the driver.
If the IP address is not provided in the command line, the program will list the installed servers and total
ports on the screen. You will need to choose a server from the list for deletion.
Removing Linux Driver Files
A utility is included that will remove all driver files, mapped TTY ports, and unload the driver. Enter the
directory
/usr/lib/npreal2/driver
and execute
mxuninst
to uninstall the driver. This program will
perform the following actions:
1.
Unload the driver.
2.
Delete all files and directories in /usr/lib/npreal2.
3.
Delete directory /usr/lib/npreal2.
4.
Modify the system initializing script file.
UNIX Fixed TTY Drivers
A fixed TTY driver is provided that will map UNIX host TTY ports to NPort serial ports. Once the mapping has
been set up, UNIX users and applications can connect to an NPort serial port as if it were a local TTY port.
This driver has been designed and tested for most UNIX systems. Please check
http://www.moxa.com
for
the latest UNIX systems support.
