Requesting a Status Dump
The client may request that the Videohub Server resend the complete state of any status block by
sending the header of the block, followed by a blank line. In the following example, the client requests
the Videohub Server resend the output labels:
OUTPUT LABELS:↵
↵
ACK↵
↵
OUTPUT LABELS:↵
0 output label 1↵
1 output label 2↵
2 output label 3↵
…
↵
Checking the Connection
While the connection to the Videohub Server is established, a client may send a special no-operation
command to check that the Videohub Server is still responding:
PING:↵
↵
If the Videohub Server is responding, it will respond with an ACK message as for any other recognized
command.
