Connecting a
Computer to a
Serial Port
On the SuperStack 3 Call Processor, the NBX 100 Call Processor, and on
some of the NBX cards, you can connect a computer to a serial port and,
by running a terminal emulation program on the computer, you can
obtain information about the status of the card or the NBX system.
You can connect a computer directly to the serial port on these cards:
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 76.
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 77.
