Installation Notes/Using TTYredirector
• If installed with the shell kit, run the shell script uninstaller:
# /usr/local/bin/ttyredirectord-uninstall
The ttyredirectord daemon is stopped and all TTYredirector tty devices immediately cease operation.
If TTYredirector is later reinstalled, all previous settings are restored.
5. Daemon Commands
The TTYredirector daemon script accepts conventional daemon script commands.
NOTE: This information is provided as an FYI for administrators. In typical situations, it is not necessary to use these commands.
/etc/rc.d/init.d/ttyredirectord start | stop | restart | status
start — Start the daemon.
stop — Stop the daemon.
restart — Stop then start the daemon.
status — Display (to stdout) PID and current status.
Using TTYredirector
1. The Command Line Utilities
The trconfig command configures TTYredirector and its devices in three ways:
• You can manage tty devices by adding them, removing them, configuring their options.
• You can specify how TTYredirector will initialize remote ports if you are using device servers that support the Telnet protocol
with RFC 2217 extensions.
• You can set general options that affect all TTYredirector TTY devices.
The trquery command enables you to display current settings by using many of the same command options as trconfig.
The trtrace command is a troubleshooting tool that provides a real-time display of TTY device activity to help diagnose
application problems.
2. Managing TTY Devices
The following trconfig commands add, delete, and manage the basic settings for individual tty devices controlled by TTYredirector.
In all commands below, dev specifies TTYredirector TTY devices and can be:
A single device name composed of A-Z, a-z, 0-9, +, -, and underscore,
or
multiple device names separate by commas, with no spaces between,
or
the value ALL, signifying all existing TTYredirector devices, can be used except with the -addtty, -deltty, and -ttylist options.
Short forms of option names appear on a line following the long form.
For the status values returned by trconfig, see the Technical Notes.
A. Adding and deleting TTYredirector TTY devices
