Compaq AlphaServer GS60 Operation Manual page 222

The set host command syntax is:
se[t] h[ost] <device_adapter>
The set host <device_adapter> command is used to connect to a remote XMI adapter
for running XMI module-resident ROM-based diagnostics, as shown in Example 7-23.
Use Ctrl/C to terminate the command and return to the primary processor.
Set host can only be issued from the boot processor, and only one set host command is
in effect at a time. Characters typed from the console terminal are passed through to
the target node. All output from the target node is displayed on the console terminal.
