NotesPort numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.

Well Known Ports: 0 through 1023.

Registered Ports: 1024 through 49151.

Dynamic/Private : 49152 through 65535.



TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.



UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.



When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.


TCP Port 4800 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.


Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.


Tip! Use our free Digital Footprint and Firewall Test to help verify you are not infected.Side note: TCP port 4800 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 4800 in the same order in which they were sent. Guaranteed communication over port 4800 is the key difference between TCP and UDP. UDP port 4800 would not have guaranteed communication in the same way as TCP.


We do our best to provide you with accurate information on PORT 4800 and work hard to keep our database up to date. This is a free service and accuracy is not guaranteed. We do our best to correct any errors and welcome feedback!


We have an external application making RFC calls into our SAP system without a problem. However, we have now decided to use SSO with Active Directory for user authentication. The user logs in to an ADFS service and the SAML response containing the user's X509 certicate is then sent through our application to SAP. For some reason port 4800 is not running on our SAP server. The error we are getting is below:


I have confirmed that the process sapgw00s is not running. I've also confirmed that our users are using SAP's Secure Login Client for SNC connections into SAP, but that the SNC traffic for the GUI is flowing over port 3200. I was under the impression that SNC GUI traffic flowed over port 4700. How do you control the ports over which SNC traffic flows?


We tried a telnet, saw the traffic flowing over the network nicely, and then getting blocked by SAP. My guess is the service sapgw00s is not running. I have the Basis team changing the snc/r3int_rfc_secure from 0 to 1 and they will reboot the SAP server tonight. Do you know if that parameter drives the start of the sapgw00s service?


1. Check the profile parameter snc/enable on your application servers. On the CI probably it is turned off, as result there is no service sapgw00s on the application server and when the other application server is trying to reach this the connection fails. For more see the following document: _nwpi71/helpdata/en/ed/fb958dd978458e99168d43f408665e/frameset.htm


2. Verify if the AS Java is able to reach the hostname using OS commands (i.e. ping, traceroute, nslookup) from the affected system. If not, please ask for internal IT team assistance to verify the resolution for the hostname issue at OS level.


Connecting to a system from SAP Logon with an SNC enabled connection attempts to reach port Gateway Secured 48XX where XX is the SAP instance number, you need to allow access to port 4800 in your case to your system.


Within a minute the MCD-4800 becomes a powerful WiFi hotspot accessible by any wireless device within a 100 meter range for up to 5 hours on internal battery power. This auto-pointing solution uses the high performance Hughes 9450TW in-motion BGAN terminal integrated with our proprietary mobile electronics for a ruggedized self-contained, in-field or on sea, user-friendly global communications link.


While the MCD-4800 is primarily used as a wireless hotspot, the front panel includes a weather sealed Ethernet port and a phone port to connect a laptop or a standard analog phone. The charge port has a watertight seal for several external power sources such as a portable solar panel, external battery, or vehicle power adapter.


The display shows current system status and remaining battery power and a light sensor allows the display to be backlit at night (the backlight may be enabled/disabled). The MCD-4800 only has one button, the power button located inside of the case which makes is easily operated by anyone.


The MCD-4800 is enclosed in a watertight hardened plastic Pelican case, and the case lid is normally closed for full operation. It operates in heavy rain and will transmit with 20mm of ice buildup before transmission issues.


It is rated at IP67, which means it can withstand immersion in water up to 1 meter. In extremely hot environments, we recommend the case lid be slightly opened for venting for long duration use to avoid heat buildup inside the case.


The MCD-4800 uses the Inmarsat BGAN satellite network for broadband Internet connectivity. It then creates a 100 meter (328 feet) Wi-Fi access point in seconds for any wireless device to connect. Wi-Fi is helpful if users wish to be inside or move around a structure untethered from the case.


The MCD-4800 case does not need to stay opened in order to operate. Simply press the power button (inside the case) and 60 seconds later it will become a wireless hotspot anywhere on the globe for up to 5 hours on the internal battery.


The power button for the MCD-4800 is inside of the case. Simply press the button to turn the system on. No other action is required for establishing a WiFi hotspot. The BGAN SIM card tray is also easily accessed from just inside the case lid.


The 802.11 WiFi antenna is mounted next to the dome. Antennas use an RP-SMA connector and can be fitted with an optional 15dBi high-gain antenna (or any other off-the-shelf antenna) for increased WiFi range.


Connecting a wireless device such as laptops, smartphones or tables to the MCD-4800 is as easy as selecting it from available access points. Wireless security is configurable from a web interface and includes MAC address filtering.


The MCD-4800 main interface is accessed via any connected browser. Status screens show battery life, internal temperature, and links the Hughes 9450TW web interface for usage totals, parameter configurations including streaming services, static IP configuration, and SMS messaging.


A watertight cap protects the RJ-45 Ethernet port from the elements. A laptop or router may be connected directly to the MCD-4800. Public IP addresses are available. Ethernet lengths can be up to 328 feet (100 meters). Specially designed waterproof Ethernet connectors are available for this RJ-45 port to use with your Ethernet cable.


While the MCD-4800 is designed for Internet connectivity, it does include a standard analog phone. The phone port is issued an international satellite phone number. Any connected phone may make and receive calls from anyone on the planet for $0.99 cents usd per minute.


Calls are easily made between other terminals, satellite phones, cell phones or standard landline phones anywhere in the world, and incoming calls are free, although the calling party is burdened with the cost of calling. Local numbers from any country can be assigned to the BGAN terminal.


Since the MCD-4800 fully operates in closed hardened case, it is ideal for harsh marine environments. Here the MCD-4800 is being used for primary crew connectivity for the Oceana Canada during their Gulf of St. Lawrence Expedition.


The MCD-4800 can operate with the lid open or closed (for rain or ocean spray) with no signal strength reduction. The case is fully watertight when closed. In this picture, a ship offloads supplies to another rig.


The MCD-4800 is an excellent solution to ocean faring vessels and oil-rigs. Here an IT specialist uses a wireless connection to establish connectivity. Wi-Fi may be shut off, and an Ethernet cable connection can be used for a more secure connection.

Strong and bitter words indicate a weak cause. - Fortune cookie wisdom RE: Reading Com Port at 4800 baud?? dabineri (Programmer)(OP)13 Nov 05 16:38Thanks, George. The documentation I have does not show 4800 baud as a valid setting but it does appear to work fine.



Thanks again, David Abineri
