4.4.2 Console Requester
sends responses
Console-user,
Console Requester operation is very simple. Requests from the high
level user
map directly to corresponding Remote Console Protocol
messages. With the exception of the Read-identity, Read-counters and
Send-console-conunand functions, none of these messages have responses;
therefore, the Requester returns completion when a simple transmit is
done.
