Hyper Terminal

Hyper Terminal is an application that runs on your PC and allows you to send and receive serial commands out of the RS-232 port on your PC. Typically, you will know what baud rate you will want to use. In this example, we use 9600 baud. If you want to communicate at 115,200 baud, then replace 9600 with 115200 everywhere below.

Open Hyper Terminal

Select "Start", "All Programs", "Accessories", "Communications", "Hyper Terminal"

You will get the pop up menu at the right.

Enter a name like "Debug 9600".

Click OK.

It will give you the "Connect To" menu.

For "Connect using" at the bottom, select "COM1" (or whatever the name is of the serial port on your PC that you will be using).

Click OK.

Set the "Bits per second:" to the appropriate speed (usually either 9600 or 115200).

Set the "Flow control:" to "None".

Click OK.

You will get something like the menu at the right. Note that the phone inside the red circle is off the hook (you will not have a red circle on yours).
