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 Table 81
.
To connect the computer to the COM1 or CONSOLE port on a board:
1 Using 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.
2 Connect the female end of the cable to an available serial port on the
computer.
3 Start the terminal emulation software and create a new connection.
4 Configure the connection to use the serial port to which you connected
the cable and to use the settings in Table 82
.
All messages associated with the board (for example, the initialization
process) appear in the terminal emulation window.
