sicontrol -- Specialix SI/XIO driver configuration and debugging
sicontrol device command [param ...]
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 settings
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 specified
port. This is not much use outside of debugging the driver.
/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)
Generally self explanatory.....
stty(1), si(4), termios(4), tty(4), comcontrol(8)
The sicontrol utility is loosely based on a utility called siconfig which
was written by Andy Rutter <[email protected]>
Specialix International do not support this device driver in any way.
