Subject: Rewrite the sicontrol man page to something remotely useful. I
 couldn't use the original, as it had unusable copyrights.

 .Sh DESCRIPTION
-.Nm Sicontrol
-is used to manage the SI/XIO driver .
-.sp
-Ask Peter Wemm <peter@haywire.dialix.com> for details.
+.Nm sicontrol
+is used to configure and monitor the SI/XIO device driver.
+.Pp
+.Nm sicontrol
+operates on the specified
+.Ar device
+to indicate which port is to be used.
+.Pp
+The special
+.Ar device
+string `-' is used to indicate the global driver settings instead.
+.Pp
+A '/dev/' is included if necessary.
+.Pp
+The following commands are used for the global settings and should be
+specified with the '-' device name.
+.Bl -tag -width 4n
+.It Cm int_throttle Op Cm value
+Configure the `aggregate interrupt throttle value'.
+The maximum number of host adapter interrupts per second is determined by:
+.Pp
+.Ar "controller CPU clock / (8 * int_throttle)"
+.Pp
+The default value at boot time is 25000.  The host adapter cpu clock is
+25Mhz.  This gives a maximum interrupt rate of about 125 interrupts per
+second.
+.Pp
+Lowering this value will increase the rate in which the host adapter can
+interrupt the operating system for attention.
+.\"
+.It Cm rxint_throttle Op Cm value
+Configure the receiver interrupt throttle value.
+The default value of 4 at boot time allows an interrupt rate of
+approximately 25.
+.Pp
+Lowering this value will increase the rate in which the host adapter can
+interrupt the operating system to empty the receviver fifos.
+.\"
+.It Cm nport
+Returns the number of ports under the control of the device driver.
+.El
+.Pp
+The following commands are used for the individual ports and should be
+specified with a device name from /dev.
+.Bl -tag -width 4n
+.It Cm mstate
+Shows the current incoming modem control signals.
+.It Cm ccbstat
+Shows the current "ccb" structure for the specified port. This is not of
+much use outside of debugging the driver and determining why a port is
+wedged.
+.It Cm ttystat
+Shows the current "tty" structure that the kernel has for the specified port.
+This is not much use outside of debugging the driver.
