Virtual Serial Communication

The Universal Asynchronous Receiver/Transmitter (UART) controller is the key component of the serial communications subsystem of a computer. The UART takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Serial transmission is commonly used with modems and for non-networked communication between computers, terminals and other devices. There are two primary forms of serial transmission: Synchronous and Asynchronous. Depending on the modes that are supported by the hardware, the name of the communication sub-system will usually include a A if it supports Asynchronous communications, and a S if it supports Synchronous communications. Some common acronyms are:

  • UART: Universal Asynchronous Receiver/Transmitter
  • USART: Universal Synchronous-Asynchronous Receiver/Transmitter

In This Post we will talk about Virtual Serial Communication and how to emulate serial port to use in you application or simulation.

VMWare NAT Server Lag Solution (Windows)

In the last few months, my internet server connection was too bad and i was getting disconnect from it and after while the connection is getting back and internet too but the NAT Server don’t sense that and the Virtual Machines don’t get any internet connection, i tried to ping Google from the Virtual Machines and the same problem, no results and the only solution is to restart my pc to fix this problem.

But at last i found the solution to this problem without restarting your PC, just restart the NAT Service from Services Manager in Windows.

Steps

  • Goto Control Panel -> Administrative Tools -> Services.
  • At Services Manager Search for “VMware NAT Service” and Restart It.

That’s it and all connection will be restored in your Virtual Machines without Restarting your PC.
