Setting Up a Serial Connection
If you are having difficulty establishing LAN connections and need to
perform the LAN performance verification tests, you will need a serial
connection.
To set up a serial connection, you will need to:
•
Set the serial configuration switches
•
Connect the HP E3491A Pentium Probe to the RS-232 interface
•
Connect a serial cable between the host computer and the
HP E3491A Pentium Probe
•
Verify communications
Serial connections on a workstation
If you are using a UNIX workstation as the host computer, you need to
use a serial device file. If a serial device file does not already exist on
your host, you need to create one. Once it exists, you need to ensure
that it has the appropriate permissions so that you can access it. See
the system documentation for your workstation for help with setting
up a serial device.
Serial connections on a PC
Serial connections are supported on PCs. You must use hardware
handshaking if you will use the serial connection for anything other
than setting LAN parameters.
If you are using a PC as the host computer, you do not need to set up
any special files.
