Remote console for monitor and control of system firmware
View Patent ↗A system and method are provided for permitting a console to be connected to an external port of a first node for monitoring and controlling the first node in a default mode. The first node may also operate in a terminal mode in which an internal port of the first node is connected to an internal port of a second node to permit the console and the second node to communicate via the first node.
1. A method for providing remote control and monitoring of multiple data processing devices, the method comprising:
providing a primary data processing device having a first set of ports for connecting to an associated set of secondary data processing devices and a second port for connecting to a console;
specifying one of the first set of ports;
sending data received from the console at the second port over the specified port to the secondary device associated with the specified port;
sending data received at the specified port from the secondary device associated with the specified port to the console over the second port;
receiving an abort command at the second port;
ceasing to send data received from the console at the second port over the specified port to the secondary device associated with the specified port in response to receiving the abort command.
2. The method of claim 1 , wherein the first set of ports comprises serial ports.
3. The method of claim 1 , wherein the second port comprises a serial port.
4. The method of claim 1 , further comprising sending a password or key sequence over only the specified port in response to receiving the specify command.
5. A method for providing remote control and monitoring of multiple data processing devices, the method comprising:
providing a primary data processing device having a first set of ports for connecting to an associated set of secondary data processing devices and a second port for connecting to a console;
sending monitoring data originating at the primary data processing device over the second port;
receiving a specify command over the second port, the specify command identifying at least one of the first set of ports;
ceasing to send monitoring data originating at the primary data processing device over the second port in response to receiving the specify command;
sending data received from the console at the second port over the specified port to the secondary device associated with the specified port;
sending data received at the specified port from the secondary device associated with the specified port to the console over the second port.
6. The method of claim 5 , further comprising sending a password or key sequence over only the specified port in response to receiving the specify command.
7. The method of claim 5 , wherein the first set of ports and the second port comprise serial ports.
8. The method of claim 5 , further comprising:
receiving an abort command at the second port;
ceasing to send data received from the console at the second port over the specified port to the secondary device associated with the specified port in response to receiving the abort command.
9. A system, comprising:
a primary data processing device having a set of internal ports for connecting to an associated set of secondary data processing devices and an external port for connecting to a console;
the secondary data processing devices each comprising a set of internal ports for connecting to the internal ports of the primary data processing device;
the primary data processing device configured to operate in a default mode by sending monitoring data originating at the primary data processing device to the console over the external port of the primary data processing device;
the primary data processing device configured to operate in a terminal mode in response to receiving a specify signal that identifies one of the internal ports of the primary data processing device, the primary data processing device receiving monitoring data from one of the secondary data processing devices over the identified internal port and sending the monitoring data over the external port of the primary data processing device.
10. The system of claim 9 , wherein the primary data processing device operating in terminal mode receives command signals at the external port of the primary data processing device and sends the received command signals over the identified internal port of the primary data processing device.
