Method And Apparatus For Redirecting Input/Output Device Data In A Computer System Through Use Of Debug Registers

US Patent:
6112260, Aug 29, 2000
Filed:
Jan 31, 1997
Appl. No.:
8/791590
Inventors:
Arnold R. Colterjohn - Spring TX
Peter J. Brown - Houston TX
Douglas E. Stewart - Houston TX
Assignee:
Compaq Computer Corporation - Houston TX
International Classification:
G06F 702
G06F 1314
US Classification:
710 31
Abstract:
A computer system implements a standard modem without the use of a microcontroller. Instead, a digital signal processor is provided on an expansion card, but with direct links to the computer system itself. The code usually implemented in the microcontroller is instead implemented as a virtual modem controller to be called by the operating system of the computer itself. Further, this virtual modem controller includes a virtualized UART, that appears to the operating system software as a hardware UART, and the operating system driver software need not even have its input and output instructions replaced. Instead, debug registers are provided as breakpoints whenever an input/output instruction is executed to the I/O port range at which the UART would normally appear.
