74CHAPTER 5: SYSTEM DEBUGGING

Step 1: Start PC, and run terminal emulation program (such as Terminal of Windows3.1, or Hyper Terminal of Windows 95/Windows 98/Windows 2000/Windows NT/Windows XP/Windows ME) on PC.

Step 2: Set parameters in the Hyper Terminal of Windows98.

You must set the baud rate to 9600, data bits to 8, no parity check, stop bit to 1, and flow control to none, and select VT100 for terminal emulation. Specifically,

1Click StartProgramsAccessoriesCommunicationsHyperTerminal to access the Hyper Terminal window. The Connection Description dialog box displays.

2Click the red phone icon in the window to set up a new connection.

3Enter the name of the new connection in the Name field and OK. The Properties dialog box displays.

4Select the target serial port to be used in Connect using field, and click OK. The Port Settings Properties dialog box display.

5Set the connecting serial interface parameters. Set the bits per second to 9600, data bits to 8, Parity to None, stop bits to 1, and flow control to None, then click OK. The HyperTerminal dialog box displays.
