Installing Your NPort Device Server
This section describes how to connect an NPort device server to your serial devices for the first time. We
cover Wiring Requirements, Connecting the Power, Grounding the NPort Device Server, Connecting to the
Network, Connecting to a Serial Device, and LED Indicators.
Wiring Requirements
er components, make sure that there is at least a 2-cm clearance on all sides of the NPort device server
You should observe the following:
• Use separate paths to route wiring for power and devices. If the power wiring and device wiring paths
must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
• You can use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wires that shares similar electrical characteristics can be bundled
together.
• Keep input wiring and output wiring separate.
• Where necessary, it is strongly advised that you label wires to all devices in the system.

Connecting the Power
Connect the power line with the NPort’s power input. If the power is properly supplied, the “Ready” LED will
show a solid red color until the system is ready, at which time the “Ready” LED will change to a green color.
Grounding the NPort Device Server
Note: This section only applies if your NPort’s power input is on a terminal block.
Grounding and wire routing help limit the effects of noise caused by electromagnetic interference (EMI). Run
the ground connection from the ground screw to the grounding surface before connecting the devices.

RS-485 Port’s Adjustable Pull High/Low Resistor
For some applications, you may need to use termination resistors to prevent the reflection of serial signals.
When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Refer to Appendix B for detailed instructions on how to set the pull
high/low resistor values for different models.

ATTENTION
Before installing and the configuring the NPort Administration suite, make sure your us
system administrator.
Configuration by Windows Utility
NPort Administration Suite is an integrated software suite that bundles NPort Administrator and the IP Serial
Library, providing everything you need to manage, monitor, and modify your NPort from a remote location.
With NPort Administrator, you can easily install and configure your NPort device server over the network.
Five different sets of functions are provided to ease the installation process: Configuration, Monitor, Porting
Monitor, COM Mapping, and IP Address Report.
In this section, we will cover only the “configuration of general settings” using NPort Administrator. For
more detailed information on how to use this suite of useful utilities, refer to Chapter 6.
You may also use the web console, serial console, or Telnet to configure the device server. Refer to the
section Configuration by Web Console, Configuration by Serial Console, and Configuration by
Telnet Console for additional information on using these consoles.
Installing NPort Administrator
Download and run the setup program from Moxa’s support website (https://www.moxa.com/support/). You
may find it in the Resource section under your product page. Run NPort Administrator when the installation
has been completed.
er privilege is set as
Searching for Device Servers over a LAN
The Broadcast Search function is used to locate all NPort 5400 device servers that are connected to the
same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP
address, all NPorts connected to the LAN will be located, regardless of whether or not they are part of the
same subnet as the host.
NPort 5000 Series Getting Started
2-8
In NPort Administrator, click Search to search your LAN for NPort device servers. When your unit appears in
the search results, you may click Stop to end the search. You may also wait a few more moments for the
search to complete.
The Configuration screen will list the NPort device servers that were found on the LAN. If your unit cannot
be found, you may have a network problem. Check all cables and verify that your PC and device server are
on the same LAN. If you still have problems, try connecting the device server directly to your PC.
Before configuring the NPort, you will need to unlock the NPort first. Right-click the unit in the Configuration
screen and select Unlock in the pop-up menu. Before configuring the NPort, you will need to unlock it first.
Right-click the unit in the Configuration screen and select Unlock in the pop-up menu.
The default login is:
Username: admin
Password: moxa
For the NPort 5100, 5200, and IA5000 Series, only the password is required to log in.
Adjusting General Settings
Right-click your unit in the Configuration screen and select Configure in the pop-up menu. If your device
server is password protected (the default username is account and the default password is moxa), first
select Unlock in the pop-up menu, and then click the Network tab in the configuration window. Select the
Modify checkbox for items you would like to modify. The device server must be assigned a unique IP
address that is valid for your network. Both fixed and dynamic IP addresses are supported. Consult with
your network administrator if you are not sure how to set these parameters.
Also, For the NPort 5100, 5200, and IA5000 Series, only the password is required to log in.
NPort 5000 Series Getting Started
2-9
When you are ready to restart the device server with the new settings, click OK.
Static IP Addresses
For most applications, you will assign a fixed IP address to the device server. To assign a static (fixed) IP
address, the IP Configuration parameter must be set to Static, which is the default setting. You may then
modify the IP Address and Netmask parameters.
Dynamic IP Addresses
For certain network environments, your device server’s IP address will be assigned by a DHCP or BOOTP
server. In this case, instead of assigning the device server’s IP address, you will need to configure the
device server to receive its IP address from the appropriate server. Set the IP Configuration parameter to
DHCP, BOOTP, or DHCP/BOOTP, depending on your network environment. The IP Address and
Netmask parameters will be unavailable for editing since these parameters will be assigned automatically.
If you are not sure whether you need to configure your device server for a dynamic or static IP address,
consult the administrator who set up the LAN.
Verifying Network Settings
If your device server has been configured correctly, you should be able to ping its IP address from your PC.
First, make sure that your PC and device server are on the same subnet, and then ping the device server’s
address. If no response is received, check your cables and network settings.
Configuring Device Port Operation Mode
This section covers configuration of a device port’s operation mode. The operation mode determines how
the device port will interact with the network. Which operation mode you select will depend on your specific
application. Refer to the chart at the end of this section for guidance on selecting the most appropriate
operation mode. For additional information on each operation mode, refer to Chapter 4 and Chapter 5.
Adjusting Operation Mode Settings
The operation mode parameters for each device port can be configured through NPort Administrator. Open
your device server’s configuration window using the same method you used to adjust the network

Mapping COM Port to Device (only required when operation
mode is set to Real COM or RFC2217)
This section covers how to map the COM ports on a Windows PC to NPort device ports. The mapping will
allow Windows software to access serial devices over the network as if they were local COM devices,
providing instant device networking without software migration. COM mapping is supported in Real COM and
RFC2217 modes only.
The following instructions are for device ports operating in Real COM mode. For device ports operating in
RFC2217 mode, follow the instructions for your particular driver. Real COM mode also supports TTY port
mapping on Linux and UNIX systems.
Specifying the Target Device Server
In NPort Administrator, click COM Mapping in the Function panel to open the COM Mapping window.
Right-click on an empty line in the COM Mapping window. Select Add Target in the pop-up menu to assign
your device server as the mapping target.
A list of NPort device servers that have been found by NPort Administrator will appear. Select your device
server and click Finish.

Assigning COM Port Number to Device Port
The COM Mapping screen shows a list of available device ports on the network. Right-click the target
device port and select COM Settings in the pop-up menu.
On the Basic Settings screen, select the COM port number that will be mapped to the device port. You can
map multiple COM ports at the same time by selecting the Auto Enumerating check box to number the
COM ports automatically.
On the Serial Parameters screen, adjust the settings to match your device. These settings, which are only
used for serial printers, must also match the settings on the device port. Click OK when you are satisfied
with your changes.

Advanced Settings
(See Chapter 6 for detailed information about NPort Administrator’s Advanced Settings.)
Tx Mode: In Hi-Performance mode, the driver immediately issues a “Tx Empty” response to the program
after sending data to the NPort. In Classical mode, the driver sends the “Tx Empty” response after
confirmation is received from the NPort. Classical mode is recommended if you want to ensure that all data
is sent out before further processing.
FIFO: Tells the driver whether or not to use FIFO transmission.
Network Timeout: Specifies when an open, close, or serial parameter change operation will time out.
Fast Flush: When enabled, the driver flushes only the local buffer on the host for a Win32 PurgeComm()
function call. When disabled, both the local and remote buffers are flushed. If your application uses
PurgeComm() and it performance seems sluggish, try enabling Fast Flush.
Always Accept Open Requests: Even if the driver cannot establish a connection with the NPort, the user's
software will still be able to open the mapped COM port, the same as with an onboard COM port.
Ignore TX Purge: The application can use Win32 API PurgeComm to clear the output buffer and terminate
outstanding overlapped write operations. Select Ignore TX Purge if you do not want the output buffer to
be purged.
Apply Change
Right-click COM Mapping in the Function panel. Select Apply Change in the pop-up menu to save the
current COM mapping settings. Your application will now be able to access the target serial device using the
COM port.

You must assign a valid IP address to the NPort before it will work in your network environment. Your
network system administrator should provide you with an IP address and related settings for your network.
The IP address must be unique within the network (otherwise, the NPort will not have a valid connection to
the network). You can choose from four possible IP configuration modes—Static, DHCP, DHCP/BOOTP,
and BOOTP—located under the web console screen’s IP configuration dropdown box.
Method Function Definition
Static The user must define the IP address, Netmask, and Gateway.
DHCP The DHCP Server assigns the IP address, Netmask, Gateway, DNS, and Time Server
DHCP/BOOTP The DHCP Server assigns the IP address, Netmask, Gateway, DNS, and Time Server, or
the BOOTP Server assigns the IP address (if the DHCP Server does not respond).

IP Address Report
When NPort products are used in a dynamic IP environment, users must spend more time with IP
management tasks. For example, if the NPort works as a server (TCP or UDP), then the host, which acts as
a client, must know the IP address of the server. If the DHCP server assigns a new IP address to the NPort,
the host must have some way of determining the NPort’s new IP address.
NPort products help out by reporting their IP address periodically to the IP location server, in case the
dynamic IP has changed. The parameters shown below are used to configure the Auto IP report function.
There are two ways to develop an “Auto IP report Server” to receive NPort’s Auto IP report.
1. Use Device Server Administrator’s IP Address Report function.
2. Auto IP report protocol, which can receive the Auto IP report automatically on a regular basis, is also
available to help you develop your own software. Refer to Appendix E for details about the Auto IP

Accessible IP Settings allow you to add or block remote host IP addresses to prevent unauthorized
access. Access to the NPort is controlled by an IP address. That is, if a host’s IP address is in the accessible
IP table, then the host will be allowed to access the NPort. Three setting types are described below:
• Activate the Accessible IP list
Operation modes are NOT allowed for IPs NOT on the list. IPs that are not on the list will not be granted
when communicating with NPort via Operation mode
• Apply additional restrictions
All device services are NOT allowed for IPs NOT on the list. Services will not be granted for IPs that are
not on the list. Please note that all IPs will still have access if the IP list is empty, even though the
function is enabled.
Tip: For exact IP identification, the netmask needs to be 255.255.255.255.

options are available. If Mail is selected, an e-mail will be sent. If Trap is selected, an SNMP trap will be
sent. The Relay Output option is available for NPort IA5000/IA5000A series.
Cold start
Refers to starting the system from power off (contrast this with warm start). When performing a cold start,
the NPort will automatically issue an auto warning message by e-mail, or send an SNMP trap after booting
up.
Warm start
A warm start refers to restarting the computer without turning the power off. When performing a warm
start, the NPort will automatically send an e-mail, or send an SNMP trap after rebooting.
Authentication failure
An authentication failure event is triggered when the user inputs an incorrect password from the Console or
Administrator. When an authentication failure occurs, the NPort will immediately send an e-mail or SNMP
trap.
IP address changed
An IP address changed event is triggered when the user has changed the NPort’s IP address. When the IP
address changes, the NPort will send an e-mail with the new IP address before the NPort reboots. If the
NPort is unable to send an e-mail message to the mail server within 15 seconds, the NPort will reboot
anyway, and abort the e-mail auto warning.

reboots. If the NPort is unable to send an e-mail message to the mail server within 15 seconds, the NPort
will reboot anyway, and abort the e-mail auto warning.
Power failure (this event type is only applicable to NPort IA5000/IA5000A series)
NPort IA5000/IA5000A series NPorts have two DC power inputs for redundancy. Different approaches are
used to warn engineers automatically, including by email and by relay output. Users can connect to Monitor
Relay Output from the web console to check which event caused the warning. The relay output will be
canceled after the power recovers, or by selecting “acknowledge event” using the web console or Telnet.
When the Relay Output is sending a warning, the Ready LED will flash red until the warning event ceases.

3. Cybersecurity Considerations
With cyberattacks growing in number and sophistication, network device vendors are adding functions
geared towards protecting sensitive business and personal information. Moxa has dedicated itself in this
area by developing measure to make sure all the products can and will meet the security standard, so
customers will use Moxa’s product without too much to worry about. There are certain details that Moxa
cannot do alone; customers and Moxa need to work together to build up a much secured environment to
defend against all kinds of cyberthreats. This chapter introduces the essential steps to enhance the
cybersecurity of Moxa’s products. Customers may need to refer to other sections in the user manual for
exact settings or commands.The following topics are covered in this chapter:

Updating Firmware
When a customer buys a product from Moxa or reseller, Moxa may have already pushed out a newer version
of firmware and that is likely to have enhanced the security features included. It is suggested to always
update to latest firmware. Please check with Moxa’s support website for further details.
Turn Off Unused Service and Ports
Imagine living in a house that has many entrances. If all the doors and windows are left unlocked or even
open, it sends a message of welcoming to intruders out there. It is always recommended to turn off services
and ports that are not in use to reduce the chances of being attacked.
Turn Off Moxa Service After Installation
Moxa Service is extremely helpful for first-time installation as it helps the device to be discovered in a local
area network (LAN). Once the installation is completed, this service should be turned off for safety reasons;
however, once it is turned off, a utility such as Moxa’s DSU (Device Search Utility) is no longer seeking for
the device, and only by the IP and login with username and password will have the access to the product.
Turn On Services That Are Necessary
There are services that were designed some while ago, but then cybersecurity wasn’t much of an issue,
therefore the design’s considerations didn’t quite cover cybersecurity. Below is a list of services that are
recommended to turn on only when necessary:
• HTTP/HTTPS: If the web console is required to access the product, it is recommend to use HTTPS over
HTTP
• Telnet: Only enable Telnet if command line is required to manage the product
• SNMP: If using Simple Network Management Protocol for remote device monitoring and management,
this should be turned on. It is strongly advised to change the default community name once enabled and
also set SNMP to send a trap if authentication failures happen.

Limited IP Access
Limiting the number of IP addresses that can access the product is one of the most effective way of blocking
unwanted intruders. If there are only limited desktop/notebook/mobile devices that would access the
product, grant those IPs access.

Account and Password
• There is a default username and password for first-time installation; it is strongly suggested to
change the password after installation has been done.
• Use your own passwords for users of the devices. If possible, also change the default name of the
account, for example, don't name admin group "admin" before the device is deployed.
• Use strong passwords. The devices support a function to check if the passwords are strong enough.
You can enable the function to help you check whether the passwords are strong enough.
• Use account login failure lockout feature to prevent unwelcome access
System Log
System log can contain all kinds of activities that are happening on your NPort, such as Login Fail, IP
Changed, Password Changed, Config Changed, etc. Check the log periodically to examine any abnormal
behavior.
Testing the Security Environment
Besides these devices that support those protective functions, network managers can follow a number of
recommendations to protect their network and devices.
To prevent unauthorized access to a device, follow these recommendations:
• Testing tools for cybersecurity environment checks are available. Some may provide limited free use, for
example, Nessus. These tools help identify possible security leaks in the environment.
• The device should be operated inside a secure network, protected by a firewall or router that blocks
attacks via the Internet.
• Control access to the serial console as with any physical access to the device.
• Avoid using insecure services such as Telnet and TFTP; the best way is to disable them completely.
• Limit the number of simultaneous Web Server, Telnet, and SSH sessions allowed.
• Periodically, change the passwords.
• Backup the configuration files periodically and compare the configurations to make sure the devices work
properly.
• Audit the devices periodically to make sure they comply with these recommendations and/or any internal
security policies.
• If there is a need to return the unit to Moxa, make sure encryption is disabled and that you had already
backup the current configuration before returning it.

operation mode that uses a driver installed on the host computer, and operation modes that rely on TCP/IP
socket programming concepts. After choosing the proper operation mode in this chapter, refer to Chapter 5
for detailed configuration parameter definitions.

Overview
NPort serial device servers network-enable traditional RS-232/422/485 devices. A serial device server is a
small computer equipped with a CPU, real-time OS, and TCP/IP protocols that can bi-directionally translate
data between the serial and Ethernet formats. NPort device servers that are connected to a network that
with access to the Internet can be accessed from a computer located anywhere in the world.
Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from
various kinds of instruments. Since NPort serial device servers network-enable instruments equipped with
an RS-232/422/485 communication port, your SCADA and data collection system will be able to access all
instruments connected to a standard TCP/IP network, regardless of whether the devices are used locally or
at a remote site.
An NPort serial device server is an external IP-based network device that allows you to expand the number
of serial ports for a host computer on demand. As long as your host computer supports the TCP/IP protocol,
you won’t be limited by the host computer’s bus limitation (such as ISA or PCI), or lack of drivers for
various operating systems.
In addition to providing socket access, the NPort also comes with a Real COM / TTY driver that transmits all
serial signals intact. This means that you can continue using your existing COM/TTY-based software, without
needing to invest in additional software.
Three different socket modes are available: TCP Server, TCP Client, and UDP Server/Client. The main
difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the
recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making
it possible to offer speedier delivery. UDP also allows data to be unicast to only one IP address, or multicast
to groups of IP addresses.

One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to continue
using RS-232/422/485 serial communications software that was written for pure serial communications
applications. The driver intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then
redirects it through the host’s Ethernet card. At the other end of the connection, the NPort accepts the
Ethernet frame, unpacks the TCP/IP packet, and then sends it transparently to the appropriate serial device
attached to one of the NPort’s serial ports.

5600, and NPort 5600-8-DT/DTL Series.
RFC 2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the NPort to a local COM port on
the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third
party drivers supporting RFC2217 are widely available on the Internet and can be used to implement Virtual

serial device is connected to the RS-232/422/485 port of the other NPort. The two NPort units are then
connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more
advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair
Connection Mode transparently transfers both data and modem control signals (although it cannot transmit
the DCD signal) between the two NPorts.
Ethernet Modem Mode
Ethernet Modem Mode is only supported by the NPort IA5000/IA5000A, NPort 5000A, NPort
5000AI-M12, and NPort 5100 series.
Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not
support TCP/IP Ethernet. By connecting one of NPort’s serial ports to the MS-DOS computer’s serial port, it
is possible to use legacy software originally designed to transmit data via modem, but now transmit the
data over the Ethernet.
NPort 5000 Series Choosing the Proper Operation Mode
4-5
Reverse Telnet Mode
Console management is commonly used by connecting to Console/AUX or COM ports of routers, switches,
and UPS units. Rtelnet works the same as TCP Server mode in that only one TCP port is listened to after
booting up. The system then waits for a host on the network to initiate a connection. The difference is that
the TCP Server mode does not provide the conversion function provided by Telnet. If the connected devices
need to use the CR/LF conversion function when controlling, then users must choose Reverse Telnet mode.
PPP Mode
PPP Mode is only supported by the NPort 5600 Series.
The NPort 5000 provides dial-in access for ISPs and enterprises that need a remote access solution. When a
user at a remote site uses a PPP dial-up connection to access the NPort 5600, the NPort 5600 plays the role
of a dial-up server, but also ensures that the user has legal access to the network by verifying the user’s
identity with the NPort 5600 User Table.
Disabled Mode
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

5. Advanced Operation Mode Settings
Your NPort’s serial ports can be configured to use one of several operation modes, such as Real COM mode
or Reverse Telnet mode. In this chapter, we explain the settings for every parameter of every operation
mode.
The following topics are covered in this chapter:

Overview
A device port’s operation mode determines how the port interacts with the network. Depending on your
application and device, you may have the option of choosing between two or more operating modes. For
each mode, the default settings should work for most applications. Modify these settings only if absolutely
necessary for your application. The operation mode and related parameters can be configured through NPort
Administrator. The same parameters may also be configured using the web console, Telnet console, or serial
console.

When to Make Adjustments
The default settings for each operation mode are designed to work for most applications and usually do not
need to be modified. However, adjustments may be required for the following situations:
• You need to control network data packing using specific delimiter characters.
Adjust Delimiters 1 and 2 and Delimiter process.
• Multiple hosts will simultaneously access the attached device.
Adjust Max Connection, Ignore Jammed IP, and Allow driver control.
• Data will be broadcast from the serial device to multiple network destinations.
Adjust Destination IP 1 through 4.
• You are using Pair Connection modes to connect two serial devices over Ethernet.

Using Pair Connection Modes
For some applications, you may want to configure two serial devices to communicate directly with each
other over the network. This can be done with a pair of NPort device servers configured for Pair Connection
Master/Slave modes. Configure one device port on one of the NPorts to Pair Connection Master mode, and
one device port on the other NPort to Pair Connection Slave mode. It doesn’t matter which NPort is the
master and which NPort is the slave.
For the device port configured for Pair Connection Slave mode, designate a Local TCP port to be used for
communication. For the device port configured for Pair Connection Master mode, enter the slave’s IP
address and Local TCP port as the Destination IP.
Once both device ports have been configured, the attached serial devices will communicate over Ethernet as
if they were connected by a serial cable. The two NPorts can be connected by an Ethernet cable, or they can
be connected to the same network.

UDP Multicast
A multicast is a packet sent by one host to multiple hosts. In multicast mode, each host that belongs to a
specific multicast group will receive multicast packets for that group. For a host to be configured as a
multicast receiver over the Internet, the must inform the routers on its LAN. The Internet Group
Management Protocol (IGMP) is used to communicate group membership information between hosts and
routers on a LAN. The NPort 5000 Series supports IGMP version 2. The NPort 5100, NPort 5200, IA5000
Series do not support IGMP function.

Type the IP address (e.g., 239.1.1.1) assigned to the multicast group in the Begin column. The NPort will
automatically add the Group, and receive all packets from this group as required by the multicast function.
Pair Connection Mode
Pair Connection Mode employs two NPort device servers in tandem, and can be used to remove the 15-
meter distance limitation imposed by the RS-232 interface. One NPort is connected from its RS-232 port to
the COM port of a PC or other type of computer, such as a hand-held PDA, and the serial device is
connected to the RS-232 port of the other NPort. The two NPort device servers are then connected to each
other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup,
they communicate with each other over a WAN (i.e., through one or more routers). Pair Connection Mode
transparently transfers both data and modem control signals (although it cannot transmit the DCD signal)
between the two NPort device servers.
Pair Connection Master Mode
When using Pair Connection Mode, you must select Pair Connection Master Mode for the Operation mode
of one of the NPort device servers. In effect, this NPort will be acting as a TCP client.

Dial-in
The NPort listens for a TCP/IP connection request from the remote Ethernet modem or host. The NPort’s
response depends on the ATS0 value, as outlined below.
ATS0=0 (default):
The NPort will temporarily accept the TCP connection and then send the RING signal out through the serial
port. The serial controller must reply with “ATA” within 2.5 seconds to accept the connection request, after
which the NPort enters data mode. If no “ATA” command is received, the NPort will disconnect after sending
three “RING” signals.
ATS0≥0:
The NPort will accept the TCP connection immediately and then send the CONNECT <baud> command to
the serial port, in which <baud> represents the baudrate of the NPort’s serial port. After that, the NPort
immediately enters data mode.
Dial-out
The NPort accepts the AT command ATD <IP>:<TCP port> from the serial port and then requests a TCP
connection from the remote Ethernet Modem or PC. This is where <IP> is the IP address of the remote
Ethernet modem or PC, and <TCP port> is the TCP port number of the remote Ethernet modem or PC. Once
the remote unit accepts this TCP connection, the NPort will send out the CONNECT <baud> signal via the
serial port and then enter data mode.
Disconnection Request from the Local Site
When the NPort is in data mode, the user can drive the DTR signal to OFF, or send +++ from the local
serial port to the NPort. The NPort will enter command mode and return NO CARRIER via the serial port,
and then input ATH to shut down the TCP connection after 1 second.
