CP/M Plus on ZX Spectrum +3 has ability to load device drivers from normal disk files (with .fid extension) on boot. A Spectranet device brings networking abilities to the Spectrum computers. This driver allows connection to a remote disk image registered as N: and a remote character device (e.g. serial console) registered as SPCNET: (namely, one can type `DEVICE aux:=spcnet` to redirect AUX: to SPCNET: and use it as a serialport over ethernet).
sercd is an RFC 2217-compliant serialport redirector. It lets you share a serialport through a network. It is based on sredird. The RFC2217 protocol is an extension to telnet and allows changing communication port parameters.
ESP8266 (ESP-01) + Serial Commands + Flespi Broker
ESP-01, the simplest USD 1.50.- ESP8266 gets a firmware that allows the user to control it by serial port. Therefore it can be used along with any terminal, computer or microcontroller, which is equipped with a serial port (or USB port)

Retool lets you generate dashboards, admin panels, and workflows directly on your data. Type something like “Build me a revenue dashboard on my Stripe data” and get a working app with security, permissions, and compliance built in from day one. Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.
Contains a framework for Coldfire MCUs like 52254.
The framework supports a Command Line Interface (CLI) that may work from Serial port, USB or ENET.
The framework uses Processor Expert and IDE requirement is MCU Eclipse 10.4 from Freescale.
Includes the FunkOS Realtime Operating System by Funkenstein Software Consulting, available at http://funkos.sourceforge.net
Mainly it is a support package for the development board Perseus, but I have ported also the RTOS to MCF52233DEMO...
The serial LCD module using ATmega8 along with easy arduino library.
serialLCD is Arduino based open-source project. It contains ATmega8 with given firmware file & the arduino library. The ATmega8 can be replaced by ATmega168/328. ATmega8 uses its 8MHz internal oscillator to reduce hardware (atmega8 no-xtal bootloader is used). The arduino library uses SoftwareSerial internally to communicate ATmega8 via digital pin 6 (only for uno/duemilanove or clone with atmega8/168/328, not for mega & due). Only one wire simplex serial communication at baudrate 9600 is...
