E. Automatically restoring failed connections
trconfig -tty dev -restore Y|N
trconfig -y dev -r Y|N
Y — If the network connection to the server fails, attempt to restore it and continue operation. For more information, see
the Technical Notes.

Any combination of chown, chgrp and chmod options can be used.
owner and group must exist. Default settings for both depend on the version of Linux being used.
mode is 3 digits following the UNIX chmod convention for setting read and write permissions for owner, group, world. The
default setting is 666, providing access for all users. Allowed values for each digit are:
0 — no access
6 — read and write access
If the tty option is omitted, settings for chown, chgrp, and chmod options modify the default used for any TTY device that has
not been given its own setting using the tty option.
G. Resetting and copying device settings
trconfig -tty dev -reset
All options for the TTY devices are set to default values.
This command does not affect the settings of general options.
NOTE: No other command options can be used.
trconfig -tty dev -copyfrom source-dev
trconfig -y dev -c source-dev
All option settings for the source-dev device are copied to all devices specified by dev.
No other options can be used with this command.
H. Delaying the close of the device
trconfig -tty dev -ptydelayclose c
trconfig -y dev -t c
c — The number of milliseconds to delay closing the connection to the server after the TTY device has been closed.
Default value is zero (no effect).
For a related global option that applies to all TTY devices, see -delayclose in General Options.
