Sets typematic rate.
#include <sys/inputdd.h>int ioctl (FileDescriptor, KSTRATE, Arg)
int FileDescriptor;
uint * Arg;
The KSTRATE ioctl subroutine call changes the rate at which a pressed key repeats itself, specified in number of repeats per second. The minimum rate is 2 repeats per second, and the maximum rate is 30 repeats per second.
When keyboard diagnostics are enabled, the KSTRATE ioctl subroutine call fails and sets the errno global variable to a value of EBUSY.
| Item | Description |

| FileDescriptor | Specifies the open file descriptor for the keyboard. |
