.SH NAME

.RI [master] 
.RI [slave]

.SH DESCRIPTION
This manual page explains the way to use the 
.B irqtune
program. This program changes the IRQ priority of devices to allow devices that require high priority and fast service (e.g. serial ports, modems) to have it.

With irqtune, a 3X speedup of serial/modem throughput is possible.
