Configuring connections

Use the following links to configure BARR/CHANNEL Offload connections. BARR/CHANNEL Offload allows you to physically connect your Windows-based computer to your mainframe channel. It emulates multiple mainframe-attached tape devices and allows you to print from the mainframe to your local network printers.

If you are adding a new device definition to the mainframe, you must configure the host before you use BARR/CHANNEL Offload. If you are replacing an existing channel-attached tape drive, you do not need to configure the host.
