On a PC Game that i play there r multiple ways to connect and play against other humans. One is "direct cable connection" and it says that i need a "null-modem cable that connects the computers by a free serial port on each computer." 2 questions, what is the serial port and what is a null-modem cable? Also where would i buy a "null-modem" cable?

had two onboard serial ports [that's what they are called in the BIOS]. Most newer computers have one or possibly none.

If two one was normally a DB25 [25 pin connector] the other DB9 [9 pin connector].

Due to the that they may not be used and you want to use it, you may have to go into the BIOS to enable the port. Many disable them because they qwaste an IRQ and address if they are not to be used.

The null modem aspect simply makes the output wires of one end of the cable the input wires at the other end and vice versa. The normal cable the output wires would be on the same pins at each end of the cable.

Are You Sure You Need A Null-Modem Cable?

Please tell us EXACTLY what computer/s you have set up and how they currently connect to the internet? Are the computers close to each other or in separate rooms? Or are you trying to play the game against other humans over the internet.. The easiest method for playing games among friends in the same household on the same network, if you've got a broadband connection, is to use a router to connect each of the computers to a network and then connect and share files between them.

But we'll need to know the specifics of your setup.

To answer your questions specifically, see the links below:

Serial port:

Null-modem/laplink cable:

Hope this helps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
