Abstract

A communications device comprising an embedded application-specific device driver for an application-specific display and an embedded remote access application that execute on a processor. The embedded application-specific device driver is configured to communicate data with a communication (COM) port via a serial port and to provide a video signal to the application-specific display. The embedded remote access application is configured to remotely access the application-specific display and to communicate display data via a network.

Claims

1. A communications device comprising:

a processor;

an embedded application-specific device driver for an application-specific display, wherein the embedded application-specific device driver executes on the processor and is configured to communicate data with a communication (COM) port via a serial port and to provide a video signal to the application-specific display;

a COM port server that, together with a COM port client located on a separate device, establishes COM port redirection over a network and communicates with a serial port;

a virtual serial port application connected between and co-located with the embedded application-specific device driver and the COM port server, wherein the virtual serial port application translates data communicated between the COM port server and the embedded application-specific device driver; and

an embedded remote access application that executes on the processor and is configured to provide remote access to the application-specific display to a client on a separate device by communicating display data via the network.

2. The communications device of claim 1, wherein the virtual serial port application includes:

a serial port driver in communication with the embedded application-specific device driver; and

a memory buffer in communication with the serial port driver to function as a virtual serial port by storing data received from the serial port driver and the COM port server.

3. The communications device of claim 1, further including a plurality of peripheral device ports, including at least one serial port and at least one universal serial bus (USB) port, and wherein the embedded remote access application is adapted to remotely access devices coupled to the serial port and USB port.

4. The communications device of claim 1, wherein the embedded application-specific device driver includes an embedded ASCII display terminal driver.

5. The communications device of claim 1, wherein the application-specific display includes a kitchen display terminal.

6. The communications device of claim 1, wherein the application-specific display includes a point of sale (POS) display terminal.

7. The communications device of claim 1, wherein the application-specific display includes a public information display terminal.

8. The communications device of claim 1, wherein the application-specific display includes a digital advertising display terminal.

9. A communications system comprising:

a communications device including;

a processor;

an embedded application-specific device driver for an application-specific display, wherein the embedded application-specific device driver executes on the processor and is configured to communicate data with a communication (COM) port via a serial port and to provide a video signal to the application-specific display;

an embedded remote access application that executes on the processor and is configured to provide remote access to the application-specific display and to communicate display data via a network; and

a COM port server that, together with a COM port client, establishes COM port redirection over the network and communicates with a serial port;

a virtual serial port application connected between and co-located with the embedded application-specific device driver and the COM port server, wherein the virtual serial port application translates data communicated between the COM port server and the embedded application-specific device driver; and

a host computer, configured to communicate with the embedded remote access application over the network and to remotely access the application-specific display via the embedded remote access application, wherein the host computer includes a COM port client to establish COM port redirection over the network with the COM port server.

10. The system of claim 9, wherein the network uses an internet protocol standard and wherein the communications device is adapted to provide access to the embedded remote access application according to an internet protocol (IP) address to allow monitoring of the application-specific display.

11. The system of claim 9, wherein the embedded remote access application includes an embedded virtual network computing (VNC) server application to communicate over the network to a VNC client on the host computer.

12. The system of claim 9, wherein the embedded remote access application includes an embedded remote desktop protocol (RDP) server application to communicate over the network to an RDP client on the host computer.

13. A system comprising:

a communications device including;

a processor;

an embedded application-specific device driver for an application-specific display, wherein the embedded application-specific device driver executes on the processor and is configured to communicate data with a communication (COM) port via a serial port and to provide a video signal to the application-specific display;

a COM port server that, together with a COM port client, establishes COM port redirection over a network and communicates with a serial port;

a virtual serial port application connected between and co-located with the embedded application-specific device driver and the COM port server, wherein the virtual serial port application translates data communicated between the COM port server and the embedded application-specific device driver; and
