Black Box IOLAND Utility
Argument
Description
-o
Used with the -p option. This option prevents the slave pseudo-tty from
closing so as to prevent any flushing of data that may occur. With this option
set, the daemon will not close the TCP connection so its use is not advised
for modems, as line hang-ups may not be initiated. It is useful for slow
printers that may lose data on pseudo-tty close.
-f<file>
Specify a different configuration file. If the pathname is relative, the current
working directory will be used.
-F
This option causes ioland to use the same pseudotty each and every time (
fixed tty). The syntax for using this option is:
ioland -F <other options> <iolan> <master device>
<slave device>
e.g: ioland -F bronto ptyp3 ttyp3
-k<n>
This option checks if the TCP connection is still alive every n seconds. If the
test fails, the child daemon process dies and signals the parent daemon that
the connection is lost.
-K
This invokes 'silent keepalives'. Normal keepalives set by the -k flag send
ASCII text messages which can go through iolan and ioland and become
visible to users and applications. The -K flag prevents this.
-s<desired
This option causes ioland to 'meter' characters sent to the unit.
character
transfer
rate>
-x<n>
Set the daemon debug/diagnostic level to n. On startup, a log file called /etc/
ioland.lg is created (if not already there). All daemons on the host will write
their debug and diagnostic messages to this file with a timestamp, daemon
process id and arguments attached to the actual diagnostic. The debug and
diagnostics levels are:
0 Lets the world know we're alive — but nothing else.
1 Reports startup options.
2 Reports connection and disconnection events.
4 Reports numbers of characters being sent/received.
8 Displays data written to the client process.
16 Displays data written to the Terminal Server.
32 Reports telnet negotiations.
64 Displays data read from Terminal Server.
128 Displays data read from the client process.
Adding the desired level numbers together can combine these levels. Care
should be taken when a high debug level is set because the log file could
grow too large.
