Something does not make sense.   Can you post a picture of the connection you  are trying to make?

I am guessing you have a windows app like hyperterminal that connects through a port to your modem.

Connecting an external monitor to your system the monitor will go to sleep unless you tell windows you have a second monitor.

Also, there is the possibility that the port (hdmi, dvi, vga) you plugged the external monitor into is not functioning.  If you have a video card then frequently you need to use the video port on the card and not the one that is built onto the motherboard.

@Babygirl7 -- after a few minutes of NOT getting any "video-input" from any computer, your monitor will enter that "low-power-sleep" mode. 

Does your monitor have multiple video-inputs? (VGA? DVI? HDMI?)

In that case, you need to select which of those inputs is to be the "active" input.

If the monitor is "listening" to the "wrong" input, it will "sleep".
