## Detailed Description

Keyboard and mouse definitions.

## Macro Definition Documentation

## ◆ AUX_BUF_SIZE

#define AUX_BUF_SIZE

Value:
512 /* This might be better divisible by
three to make overruns stay in sync
but then the read function would need
a lock etc - ick */

## ◆ KBD_CCMD_WRITE_AUX_OBUF

#define KBD_CCMD_WRITE_AUX_OBUF

Value:
0xD3 /* Write to output buffer as if
initiated by the auxiliary device */
