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 */
