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.

     Bound to be many... :-)
