In this tutorial we will learn How to communicate with an external device like a microcontroller board or modem using the Serial port of a windows PC(Windows XP,7). The software is written using C language and communicates with the Serial Port using …

Mac's are excellent tools for accessing serial device TTY ports (to console into PBX's, switches, and routers). You just need a serial to USB adapter, the right driver, and some Terminal software. You can use screen, although ZTerm, goSerial, or Mini…

BACKGROUND Many computing systems include a network interface card (NIC) to provide for communications with other systems and devices over a network. In a computing system running multiple operating systems (OSs) on multiple virtual machines, each OS…

Network Configuration TL;DR When Docker starts, it creates a virtual interface named docker0 on the host machine. It randomly chooses an address and subnet from the private range defined by RFC 1918 that are not in use on the host machine, and assign…
