Servicing the Network Call Processor Battery 371
It does not matter which computer operating system you use. As long as
the computer has a terminal emulation program that can emulate a
VT100 terminal (for example, Microsoft Hyperterminal), it can
communicate with any of the cards listed in Tabl e 81.
To connect the computer to the COM1 or CONSOLE port on a board:
1Using a standard computer serial cable (9-pin male to 9-pin female),
connect the male end of the cable to the female connector (COM1 or
CONSOLE) on the front panel of the board.
2Connect the female end of the cable to an available serial port on the
computer.
3Start the terminal emulation software and create a new connection.
4Configure the connection to use the serial port to which you connected
the cable and to use the settings in Tab le 82.
All messages associated with the board (for example, the initialization
process) appear in the terminal emulation window.
