Establishing and Testing a Connection
Connect to the Dell WYSE 3000 via Serial Port
1.
Connect the host computer to the Dell
device’s serial port using an
appropriate serial-serial or serial-USB
cable.
2.
Open a command prompt window on
the computer, and type “powershell”.
powershell
3.
Identify your computer’s serial port
names by typing the following (at
right):
[System.IO.Ports.SerialPort]::getportnames()
4.
In this guide, the screenshot at right
shows “COM3” as an available port.
5.
Type the following two commands to
open the port, replacing “COM3” with
your computer’s port name as
appropriate:
$port= new-Object System.IO.Ports.SerialPort
COM3, 9600, None, 8, one
$port.open()
6.
On the Dell device, repeat the
procedure for opening a port, but
ensure that the correct name is used by
utilizing the “getportnames() command
again. See right for the command
sequence:
powershell
[System.IO.Ports.SerialPort]::getportnames()
$port= new-Object System.IO.Ports.SerialPort
COM3, 9600, None, 8, one
$port.open()
7.
To verify that a connection has been
established, on either the computer or
the Dell device, type the following:
$port.WriteLine(“Hello World”)
