SICONTROL(8)		FreeBSD	System Manager's Manual		  SICONTROL(8)

NAME
     sicontrol -- Specialix SI/XIO driver configuration	and debugging

SYNOPSIS
     sicontrol device command [param ...]

DESCRIPTION
     The sicontrol utility is used to configure	and monitor the	SI/XIO device
     driver.

     The sicontrol utility operates on the specified device to indicate	which
     port is to	be used.

     The special device	string `-' is used to indicate the global driver set-
     tings instead.

     A /dev/ is	included if necessary.

     The following commands are	used for the global settings and should	be
     specified with the	'-' device name:

     int_throttle [value]
	   Configure the `aggregate interrupt throttle value'.	The maximum
	   number of host adapter interrupts per second	is determined by:

	   controller CPU clock	/ (8 * int_throttle)

	   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.

	   Lowering this value will increase the rate in which the host
	   adapter can interrupt the operating system for attention.

     rxint_throttle [value]
	   Configure the receiver interrupt throttle value.  The default value
	   of 4	at boot	time allows an interrupt rate of approximately 25.

	   Lowering this value will increase the rate in which the host
	   adapter can interrupt the operating system to empty the receiver
	   fifos.

     nport
	   Return the number of	ports under the	control	of the device driver.

     The following commands are	used for the individual	ports and should be
     specified with a device name from /dev:

     mstate
	   Show	the current incoming modem control signals.

     ccbstat
	   Show	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.

     ttystat
	   Show	the current "tty" structure that the kernel has	for the	speci-
	   fied	port.  This is not much	use outside of debugging the driver.

FILES
     /dev/si_control  global driver control file for use by sicontrol
     /dev/ttyA*	      terminal control ports
     /dev/ttyiA*      initial termios state devices, for use by	stty(1)
     /dev/ttylA*      locked termios state devices, for	use by stty(1)

DIAGNOSTICS
     Generally self explanatory.....

SEE ALSO
     stty(1), si(4), termios(4), tty(4), comcontrol(8)

HISTORY
     The sicontrol utility is loosely based on a utility called	siconfig which
     was written by Andy Rutter	<andy@acronym.co.uk>

     Specialix International do	not support this device	driver in any way.
