ttyadm - format and output port monitor-specific information
/usr/sbin/ttyadm [-b] [-c] [-h] [-I] [-r count] [-i msg]
[-m modules] [-p prompt] [-t timeout] [-S y | n]
[-T termtype] -d device -l ttylabel -s service
The ttyadm command is an administrative command that
formats ttymon(1M)-specific information and writes it to standard
output. The Service Access Facility (SAF) requires each port monitor to
provide such a command. Note that the port monitor administrative file is
updated by the Service Access Controller's administrative commands,
sacadm(1M) and pmadm(1M). ttyadm provides a means of
presenting formatted port monitor-specific (ttymon-specific) data to
The following options are supported:
Set the ``bi-directional port'' flag. When this flag is
set, the line can be used in both directions. ttymon
will allow users
to connect to the service associated with the port, but if the port is free,
, or ct(1C)
can use it for dialing
Set the connect-on-carrier flag for the port. If the
-c flag is set, ttymon will invoke the port's associated service
immediately when a connect indication is received (that is, no prompt is
printed and no baud-rate searching is done).
device is the full pathname of the device file for
the TTY port.
Set the hangup flag for the port. If the -h flag
is not set, ttymon will force a hangup on the line by setting the speed
to 0 before setting the speed to the default or specified value.
Specify the inactive (disabled) response message. This
message will be sent to the TTY port if the port is disabled or the
ttymon monitoring the port is disabled.
Initialize only. If the -I option is used,
ttymon will invoke the service only once. This can be used to configure
a particular device without actually monitoring it, as with software
Specify which ttylabel in the /etc/ttydefs
file to use as the starting point when searching for the proper baud
Specify a list of pushable STREAMS modules. The modules
will be pushed in the order in which they are specified before the service is
invoked. modules must be a comma-separated list of modules, with no
white space included. Any modules currently on the stream will be popped
before these modules are pushed.
Specify the prompt message, for example,
When the -r option is invoked, ttymon will
wait until it receives data from the port before it displays a prompt. If
count is 0, ttymon will wait until it receives any
character. If count is greater than 0, ttymon will wait
until count newlines have been received.
service is the full pathname of the service to be
invoked when a connection request is received. If arguments are required, the
command and its arguments must be enclosed in double quotes ("
Set the software carrier value. y will turn
software carrier on. n will turn software carrier off.
Specify that ttymon should close a port if the
open on the port succeeds, and no input data is received in timeout
Set the terminal type. The TERM environment
variable will be set to termtype.
Display the version number of the current
If successful, ttyadm will generate the requested
information, write it to standard output, and exit with a status of
0. If ttyadm is invoked with an invalid number of arguments or
invalid arguments, or if an incomplete option is specified, an error message
will be written to standard error and ttymon will exit with a
