Configuring the host device

You must configure the host for your ESCON or Bus & Tag device. The following host definitions match the default BARR/PRINT CHANNEL for IPDS connection configuration settings. If you change your configuration settings on the Connection Configuration dialog box, you must also change the host definition. The CNTLUNIT parameter on the host definition varies depending on your device.

Configuring the host is only necessary if you are adding a printer definition for the first time. If you are replacing an existing channel-attached printer, you do not need to change your host definition.
