stlstats -- Stallion Technologies multiport serial statistics display
stlstats [-hVi] [-c control-device] [-b board-number] [-p port-number]
[-d port-device]
The stlstats utility is used to display statistical information about the
ports on Stallion Technologies multiport serial boards.
The stlstats utility normally runs as a full screen menu driven application.
A help line is displayed at the bottom of each screen with the
valid input keys for this screen.
Generally the digit keys ('0' through '9') specify the number of the
device to display statistics for. Where digits alone are not enough to
access all possible devices (for example on 16 port panels) then the
first letters of the alphabet are used to access the remaining devices.
The letters 'a' through 'f' are used to access devices 10 through 15.
The 'q' key is always used to move back to the previous level screen.
The escape key can also be used to move back to the previous screen.
The first screen is a display of all ports on panel 0 of board 0. Values
displayed on this screen are a summary of the information for each port.
The statistics displayed are: driver and TTY state flags, termios flags
(cflags, iflags, oflags, lflags), RS-232 signal values (as per TIOCM signal
defines), total transmit and receive character counts.
From this screen you can look at summary information about each panel and
board installed in the system. Each board is accessed by the digit keys
('0' through '7'), while panels of each board can be cycled through using
the 'n' key.
The per port screen displays some detailed information about a particular
port. This is accessed from the board screen using the 'p' key. The
first port displayed will be port 0. To display other ports use the
digit and alphabetic keys ('0' through '9' and 'a' through 'f'). This
screen displays: driver and TTY state flags, hardware ID, termios flags
(cflags, iflags, oflags, lflags), total transmitted and received character
counts, current transmit and receive characters buffered, receiver
error counts (overruns, parity, framing, lost), software flow control
characters transmitted and received, hardware flow control actions taken,
count of transmitted and received breaks, modem signal transitions and
current RS-232 signal states.
The options are:
-h Output usage information.
-V Output version information.
-i Output only the board type information. This output is useful
for scripts or other programs that need to know a little bit
about the board (for example an automated download script). The
stlstats utility will not enter full screen interactive mode.
-c control-device
Specify the board control device through which to gather port
statistics. The default is /dev/staliomem0.
-b board-number
Specify the board number to display first. The default is to
display board 0.
-p port-number
Specify the port number to display first. The stlstats utility
will go straight into the port display screen (bypassing board
display) when this option is used.
-d port-device
Specify the port special device file (the /dev/ttyXXX file) to
display first. The board screen is bypassed and the port statistics
screen is shown immediately on start up.
/dev/staliomem0 driver control device used for statistics collection
