Communications and Modem Driver Development

Intelligraphics' team is well-versed in the development of communications drivers for modems, set-top boxes, videoconferencing hardware and other devices. Some of the comm driver technologies in which Intelligraphics has experience include:

• Synchronous, asynchronous, SDLC/HDLC, and monosync/bisync device drivers
• Serial, RF, IR and radar communications, design concepts, and performance issues
• Custom API development for proprietary protocols
• Enhanced communication drivers for all PC operating systems
• Unimodem and TAPI development
• Broadband video and audio

Intelligraphics can furnish driver development services for communications devices to manufacturers of either PC or embedded systems. Intelligraphics can provide modem development for a variety of hardware devices, from v.90 to xDSL. Intelligraphics has experience with controllerless and software modems. Our team has completed two separate projects for developing controller-less modems and can provide software modem implementations as well. Intelligraphics' broad experience in multimedia technologies makes us uniquely qualified for videoconferencing-related development. Our team has experience with H.323 and the development of drivers to support videoconferencing devices. Our engineers have expertise in IR, RF, radar, and serial communications devices. Intelligraphics' developers are familiar with IrDA and have created drivers for these devices. Our team also has experience in RF systems, both in PC and consumer environments (Bluetooth, etc.) and for industry and military applications. We have provided serial communications drivers for a number of customers. Intelligraphics' development team has provided quality driver and firmware development on a wide variety of hardware systems. Our engineers have experience with a wide array of microprocessors and microcontrollers including those by the following manufacturers:

Our team is also familiar with a number of bus architectures, such as:
 

Intelligraphics' expertise in communications devices is as diverse as the number of devices available in the marketplace. Our engineers have worked with multiple channel chips and cards from several of the top manufacturers, providing driver development for some of the following:
