Tracing NT Kernel-Mode Calls

By Dmitri Leman, April 01, 2000


April 2000/Tracing NT Kernel-Mode Calls/Figure 4

Figure 4: Sample tracer output

This is an excerpt from an output produced by a sample 
configuration file Hardware.cfg. It shows interupts and port access
in responce to letters "WDJ" typed on a keyboard. 0x61 is the
keyboard interrupt number. 0x11 and 0x91 are scan codes for the key
'W' down and up clicks, 0x20 and 0xA0 - 'D', 0x24 and 0xA4 - 'J'
