How to use Virtual Terminal in Proteus - Tech Shlok

Here I have explained you How to use Virtual Terminal of Proteus.We have created a null modem here.Null modem is a communication method to connect two DTEs (computer, terminal, printer etc.) directly using an RS-232 serial cable. The name stems from the historical use of the RS-232 cable to connect two teleprinter devices to modems in order to communicate with one another; null modem communication was possible by instead using RS-232 to connect the teleprinters directly to one another. In VT we have four pins 1.RXD - Received Data 2.TXD - Transmitted Data 3.CTS - Clear To Send 4.RTS - Request To Send For more info and other basic circuits :- http://ayushtishitu.webs.com/ http://embeddedautomation.blogspot.in/
