13 A typical session
Here is a description of how to open and close a typical session during which you will use these commands to operate a Kaleido. You can open sessions with multiple Kaleidos simultaneously; each session will have its own window on your desktop.
Open the HyperTerminal software on another computer.
A dialog will appear, asking you to enter a name for the connection and to select an icon.
![]()
A second dialog, "Connect To", will appear.
Two new fields will appear.
To be able to see the typed characters:
- Select "Properties" from the "File" menu, the "Properties" dialog box appears.
- Go to the "Settings" tab, click on the "ASCII Setup..." button located at the bottom of the dialog.
- Select "Echo typed characters locally".
- Click on the "OK" button and click again on the "OK" button from the "Properties" dialog.
The typed characters will appear in the console.
Commands can be sent to the Gateway while a session is open. There is no maximum number of commands that can be sent in a session, and it is recommended to keep a session open as long as there are commands to send, since opening a session takes a few seconds. Here is a simplified example of a session:
Open a session
send command
send command
...
send commandClose the session.
Remember that all commands sent to a Kaleido-K2 must end with a line feed (\n) or carriage return (\r). These are not required by a Kaleido Alto/Quad and will be ignored if present.
To open a session enter the openID command using the IP address of the Kaleido with which the connection has to be established.
![]()
If the Gateway receives the command and recognizes it, it will respond with the following:
![]()
If the command cannot be recognized the following message will appear:
![]()
The Kaleido is now ready to receive commands.
When no more commands need to be sent to the Kaleido , close the link to the Kaleido using the closeID command.
![]()
To end the communication session, select the "Disconnect" icon from the toolbar.
