Wow very explanative video very nice! I have a question tho', If the other device has also DTR, DSR, RTS, CTS lines, I have to connect them crossed in order to talk to other PC right? and If I want to talk with another PC with the Null modem configuration I just have to make the same wiring as in the Tx, right?

Why does Rs-232 connectors have 9/25 pin rather than other integer ?

[pradyumnakartheek]

Are the connections same as shown in the video if the sender is DCE and the receiver is DTE?

[prathyushapecchi]

I think DSR and DTR are given in reverse places
