The IBM® eServer™ i5 systems with virtual serial adapters provide a point-to-point connection between a partition and either the Hardware Management Console or another partition.
For i5/OS®, the virtual serial adapter provides for a 5250 console connection to the HMC and allows for an internal debugging connection through the HMC and to the partition. For Linux®, the virtual serial adapter provides a character console to either the HMC or an i5/OS partition.
