A session is the logical connection between two programs for data exchange; in this case a connection between the MT9750 emulation and a BS2000 application. The MT9750 session runs in a window in the Windows application. This window is the display area for the host.
When setting up your sessions, the parameters are set to meet your requirements. If you regularly communicate with different BS2000 hosts, you can configure and save separate sessions for each of them. You can use different character formats in different host applications (for example, small format characters are better suited than large format for spreadsheets) or have a different assignment of the programmable keys. Each session is assigned parameters that specify the session properties, the assignment of the programmable keys, display properties, e.g. the size of the characters displayed in the work area, and the connection setup. The parameters are individually set for every session and are only valid for that session.
These session parameters are saved locally on the PC in a session file with the file extension.MTS. Each session is also assigned the assignment of the programmable keys, which is saved in a separate file with the file extension MTK.
An active session with saved parameters is the standard. There are also three special forms of sessions:
Temporary session
Passive session
Multiple session
Temporary session
A temporary session is a one-off session whose parameters are not saved.
A temporary session is opened without a session file. The information for opening a temporary session are the same as for opening a new (standard) session. They have the same properties as saved sessions (e.g. the host ID and the host application).
When exiting a temporary session, you will be asked whether you want to save the session parameters. If you answer yes, the temporary session becomes a saved session.
Under some circumstances, temporary sessions are also a suitable way of guaranteeing limited access protection as a user has to be informed of the required connection parameters.
Passive session
Passive sessions are used to allow the connection to be established from the host side, e.g. for a bypass printing function. For bypass printing, the connection is established from the host. The remote terminal - i.e. the PC - must recognize this connection request and respond accordingly. Other than for printing, passive sessions can also be set up for other applications that establish the connection from the host.
A passive session is initially set up in the same way as an active session. Only the Mode option under Session > New > Advanced Configuration has to be changed to passive.
Multiple session
With MT9750, communication connections to multiple applications can be established simultaneously. These connections can also be to different hosts. In this case, we refer to multiple sessions.
Up to 16 instances of the MT9750 application can be started. Each application window can contain up to 64 terminal sessions and operate using customized toolbars. Under some circumstances, there may be restrictions due to the storage capacity of the PC and the memory required by other programs resident in the memory that are active in MT9750 at the same time.
Each communication connection is assigned a window that behaves like a separate 9750 data display terminal. The windows are arranged based on Windows conventions. Keyboard entries can only be made in the session whose window is currently in the foreground, while automated data exchange is also possible in the background as a batch process.
