Windows Terminal Server Serial Port ~UPD~
A Terminal Server, also known as Serial Server, connects devices with a USB, RS232, RS422, or RS485 serial interface to a local area network for transmission of serial data over Ethernet to network server applications. The most common application for Terminal Servers is out-of-band management of routers, switches, and firewalls as an efficient way to recover equipment when the network is down. It serves as a single hardware solution for a secure alternate route to monitor IT, networking, security, and power devices from multiple vendors. Terminal Servers have physical wired or wireless (LTE or WiFi) network connection on one side, and one or more serial ports on the other side. While some Serial Terminal Servers can be very simple devices, it is best practice to use a Terminal Server with advanced security functionality, data encryption, and user authentication to ensure network data transmissions, and access to network equipment, is protected.

Read this whole post, there's a lot initially but there's really just two or three small pieces. It'll be worth it because you'll be able to have a nice one click menu and drop directly into a serial port terminal on Windows in the Windows Terminal
Often when you're doing embedded systems development you'll want to monitor or talk to the COM/Serial Port just like you SSH into remote system. Folks ask questions like "How to connect to a serial port as simple as using SSH?"
Let's assume this device talks to the COM port as if it were a terminal and it's outputting stuff I want to see. I'll use this great little CLI example app for Arduino from Mads Aasvik to simulate such a device.
A terminal server connects devices with a serial port to a local area network (LAN). Products marketed as terminal servers can be very simple devices that do not offer any security functionality, such as data encryption and user authentication. The primary application scenario is to enable serial devices to access network server applications, or vice versa, where security of the data on the LAN is not generally an issue. There are also many terminal servers on the market that have highly advanced security functionality to ensure that only qualified personnel can access various servers and that any data that is transmitted across the LAN, or over the Internet, is encrypted. Usually, companies that need a terminal server with these advanced functions want to remotely control, monitor, diagnose and troubleshoot equipment over a telecommunications network.
A console server (also referred to as console access server, console management server, serial concentrator, or serial console server) is a device or service that provides access to the system console of a computing device via networking technologies.
Although primarily used as an Interface Message Processor starting in 1971, the Honeywell 316 could also be configured as a Terminal Interface Processor (TIP) AND PROVIDE terminal server support for up to 63 ASCII serial terminals through a multi-line controller in place of one of the hosts.
Historically, a terminal server was a device that attached to serial RS-232 devices, such as "green screen" text terminals or serial printers, and transported traffic via TCP/IP, Telnet, SSH or other vendor-specific network protocols (e.g., LAT) via an Ethernet connection.
Digital Equipment Corporation's DECserver 100 (1985), 200 (1986) and 300 (1991) are early examples of this technology. (An earlier version of this product, known as the DECSA Terminal Server was actually a test-bed or proof-of-concept for using the proprietary LAT protocol in commercial production networks.) With the introduction of inexpensive flash memory components, Digital's later DECserver 700 (1991) and 900 (1995) no longer shared with their earlier units the need to download their software from a "load host" (usually a Digital VAX or Alpha) using Digital's proprietary Maintenance Operations Protocol (MOP). In fact, these later terminal server products also included much larger flash memory and full support for the Telnet part of the TCP/IP protocol suite. Many other companies entered the terminal-server market with devices pre-loaded with software fully compatible with LAT and Telnet.
A console server (console access server, console management server, serial concentrator, or serial console server) is a device or service that provides access to the system console of a computing device via networking technologies.
Most commonly, a console server provides a number of serial ports, which are then connected to the serial ports of other equipment, such as servers, routers or switches. The consoles of the connected devices can then be accessed by connecting to the console server over a serial link such as a modem, or over a network with terminal emulator software such as telnet or ssh, maintaining survivable connectivity that allows remote users to log in the various consoles without being physically nearby.
Some users have created their own console servers using off-the-shelf commodity computer hardware, usually with multiport serial cards typically running a slimmed-down Unix-like operating system such as Linux. Such "home-grown" console servers can be less expensive, especially if built from components that have been retired in upgrades and allow greater flexibility by putting full control of the software driving the device in the hands of the administrator. This includes full access to and configurability of a wide array of security protocols and encryption standards, making it possible to create a console server that is more secure. However, this solution may have a higher TCO, less reliability and higher rack-space requirements, since most industrial console servers have the physical dimension of one rack unit (1U), whereas a desktop computer with full-size PCI cards requires at least 3U, making the home-grown solution more costly in the case of a co-located infrastructure.
With the EC2 serial console, you have access to your Amazon EC2 instance's serial port, which you can use to troubleshoot boot, network configuration, and other issues. The serial console does not require your instance to have any networking capabilities. With the serial console, you can enter commands to an instance as if your keyboard and monitor are directly attached to the instance's serial port. The serial console session lasts during instance reboot and stop. During reboot, you can view all of the boot messages from the start.
A terminal server, also sometimes called a communication server, is a hardware device or server that provides terminals, such as PCs, printers, and other devices, with a common connection point to a local or wide area network (WAN). The terminals connect to the terminal server from their RS-232C or RS-423 serial port. The other side of the terminal server connects through network interface cards (NIC) to a local area network (LAN), usually an Ethernet or token ring LAN, through modems to the dial-in/out WAN, or to an X.25 network or a 3270 gateway. (Different makes of terminal server offer different kinds of interconnection. Some can be ordered in different configurations based on customer need.) The use of a terminal server means that each terminal doesn't need its own network interface card or modem. The connection resources inside the terminal server are usually shared dynamically by all attached terminals.
Some terminal servers can be shared by hundreds of terminals. The terminals can be PCs, terminals that emulate 3270s, printers, or other devices with the RS-232/423 interface. Terminals can use TCP/IP for a Telnet connection to a host, LAT to a Digital Equipment Corporation host, or TN3270 for a Telnet connection to an IBM host with 3270 applications. With some terminal servers, a given terminal user can have multiple host connections to different kinds of host operating systems, such as UNIX, IBM and DEC.
The way that a terminal server works tends to vary from one vendor to the next. In the case of a Windows terminal server, the Windows operating system is configured to support multiple user sessions. This is different from other multi-session environments such as a Windows file server because the operating system renders a user interface (UI) for each of the sessions.
When a user needs to interact with a session through keyboard, mouse, or touch inputs, those inputs are made within the RDP client. The RDP client then transmits the inputs to the terminal server for processing. The terminal server is also responsible for performing all graphical rendering, although it is the RDP client that actually makes the session visible to the user.
A terminal Server and a remote desktop both serve a similar purpose. They allow a user to interact with a remote session through an RDP client. The main difference is that terminal servers run on a Windows Server, and the user is therefore provided with a Windows Server desktop. Conversely, remote desktop environments typically have desktop operating systems such as Windows 10 running within virtual machines (VM). As such, the user is provided with a true desktop operating system, rather than a session running on a server. 350c69d7ab
